: Electronic Handbrake - DIY Repair possible?

Hi,

First post so hello :d

We purchased a 2004 Megane Scenic 1.6 VVT a month or 2 ago and it's been serving it's purpose of ferrying the family about quite well.

Yesterday, my partner pulled off the drive as normal (hand brake auto disengaged as normal) but before she had got to the end of the road, there was a warning on the dash saying that the parking brake was at fault. When she got to where she was going, the hand brake will now not engage. The handle appears to do nothing (bar flash at you). No sound from the motor etc.

So, I've trawled through a number of threads on here but in all honesty, nothing has really helped much, hence why I'm posting this here.

First off. If there is no sound from the motor, can I assume it's dead or that the parking break unit is dead or is there any possiblity that a fuse could have blown? The Scenic manual is possibly the most unhelpful lump of paper I have ever come across so I can't even single out where a fuse for the unit would be. I have checked the fuses under the bonnet and in the glovebox but none appear blown but then none appear to be related to the parking brake anyway...

If the motor is dead (how can I check?), is it possible to do a DIY replacement? Can I just buy a new / used unit on ebay (the prices are eye-wateringly high :() and fit it myself or does it need programing to the car or ned the use of a dealer only tool?

Is there a guide anywhere of how to fit a new unit? WHere abouts under the car is it located?

Any other help appreciated. I hate modern cars with a passion. All this electic crap really puts me off working on them. You would never guess I'm actually quite a competant spanner monkey. :devil:

The handbrake module is under the car. Look at the rear calipers and follow the brake cables back to the module. The are programmed to the car, unfortunately. I want to get hold of a dead one to see if a repair is possible. Normally it's either a sticking pad/caliper or damage to the brake cable that causes them to fail. If I had a dead one I could investigate further. I beleive there is a relay and a motor/actuator inside the module. Relays are relatively easy to fix, I've repaired hundreds of the old Jaguar light modules. If it's the cables sticking or the caliper, these need sorting out too. There was another thread here somewhere about a polish guy that fixes them for around 70. I'd have a search for that first.

Thanks for that.

Pretty much rules out me doing it myself then :mad:

Guess I could take it off, strip it down and try to determin what caused the problem but then I still have the issue of a dead unit that needs replacing anyway.

Probably one to give to a garage and pay up then.. :mad: Wouldn't be so bad if it wasn't such a total and utter waste of money. Could stick in a new engine for cheaper than getting the handbrake fixed... :crazy:

HI http://www.renaultforums.co.uk/showthread.php?t=134347 is a post all about removal and strip down of electronic handbrake unit module located behind spare wheel under the car it's a detailed step by step with photos. Theres also another one by a member called Gonescenile which is also very useful. Hope these help you out, going through the same thing at the moment handbrake unit sounds lile a hammer drill when switching off engine but cant seem to work out why, still thats my issue hope the other members posts help.

i had the parking brake light come up on mine last week and it didnt work at all so no parking on hills for me for 2 days,was told 1.sit in car and open drivers door 2. lock doors with key card while door is still open 3 put card in slot and press start whilst pulling hand brake and pressing the button in centre of handbrake for about 5 seconds this cleard warning light and fixed the parking brake. if this dosent work after a few gose i would say is f*cked.

Thanks for the replies there.

As for resetting the handbrake using the method above, I've already tried but the method you give is slightly different the the method I found elsewhere on this forum.

The other method made out to press and hold the start button for 5 seconds, then pull out and press the handbrake lever. This didn't work.

You make out to press and hold the start button for 5 seconds whilst pulling out and pressing the handbrake lever. I have just tried it and it doesnt seem to work but then maybe I'm doing it wrong somewhere.

Which method is right?

I've had a look under the car and found the unit. Absolutely covered in crap and salt off the road. No surprise these fail in the location they are. Putting sensitive electronics behind the rear wheel of the car is never a good idea... surely Renault should have thought about that :steam:

Cables look in perfect condition and the levers on the calipers aren't seized either. Just looks like the unit has given up, unless I can get this reset thing to work.

Regardless, It's booked in to a garage on Thursday. I'm fully prepared for a wallet raping. :(

i pressed start and pulled handbrake and pressed button in centre all at the same time,i was told if this didnt reset the hand brake then ther was a high chance or ther being a mechanical fault with it

Just tried all that lot with mine and it confused the heck out of the car. At one point I couldn't even lock the doors to go inside out the cold. Anyhoo error message still there. Motor is working fine on mine. Parking brake appears to work and the brakes pull up in a good distance and in a straight line.

I'm at a loss as to what to do next, too skint to afford a new unit fitting. Will have to leave it and see if it fails MOT later this year.

I guess if the parking brake works correctly on both rear wheels and the car brakes work ok then it shouldn't fail MOT even with the error message displayed.

if all brakes are working fine then taking it to a garage to get the fault cleard off the car might be all it needs most only charge abt 20 for this.

Car is in the garage today.

They have had a look at the car and come back to us with a 850 quote.

They have managed to get the motor going and it works now but every time they remove the error code, it just comes back straight away. They spoke to a tech at renault on the phone that said when they fail, they basically need replacing. Cant clear the code and it will fail again anyway. They say the disks and pads at the back are litterally worn through and they think this is why it failed in the first place.

850 quote is to replace the unit itself (500 from renault).. and to repalce the rear disks and pads (another amazing design feature from renault incorporating the bearings into the disks.. full of bright ideas they are...) plus labour. Seems fair as even to me, disks and pads from euro car parts are 160. The part from renault is 500... so add on some labour and you get 850.

All for a handbrake. :mad: Do Renault always try to write off their cars prematurely by pricing their parts so high to make it uneconomical to repair something as simple as a handbrake on an 8 year old car?? What a joke.

Only seen this today been under the car etc last three days anyway my garage said new unit but on mine I found it was a seized nearside brake cable which I freed off by following the excellent post by gonescenile (many thanks for that) so the parking brakes fine. Also on the discs and pads theres an ebayer called directsupplies1 with 11500 transactions that do a set of two discs, four pads and hub nut for 80 plus carriage and the product is spot on, good delivery too (2 days parcelforce) Anyway I just hope you see this in time.

ours works fine but we get the beeping on startup and all the warnings ??? Iwe were advised a few months back the discs and pads were starting to show signs of needing to be replaced,and I noticed at the weekend a "clicking"coming from beside the rear driver side wheel when the engine is off??????

Just thought I would add my experience of the parking brake issue as it may help others...

My 2007 Scenic II seems to have developed an issue where on the last two occasions I have given it to a garage, it comes back with a parking brake fault.

The first was after an MOT. I managed to clear this by cycling the parking brake on and off. This was in December and there have been no reoccurances since...

...Until yesterday, when I took it in to get the tracking checked after replacing inner track rods. I don't know what these people do - maybe they don't understand the Scenic parking brake, but on the way home I realised the console display said 'Check Parking Brake.' Also, every time the parking brake was applied it would display 'Parking Brake Fault' and start beeping at me!

I was unable to rectify this by cycling the parking brake manually, as before. The brake mechanism motors fine since I can hear it clearly. After trawling the internet, mainly this forum, I tried the solution of disconnecting the battery and it worked!

Obviously there was some kind of 'logic' issue with the parking brake and it is physically sound. I refuse to take it to Renault immediately to pay 60 for a diagnostic check to clear the fault or 600 for a new computer when it was working fine until handed over to someone else to drive.

So, if your parking brake appears to be physically working but you get warning messages on the console, try disconnecting the battery and reconnecting to see if it works!

Now the manual Hand Brake sounds like a great idea. However there may be a little draw back. Have you informed your insurance company about this? the insurance company will see this as a mod and may load your premium or at the very least refuse to pay out on a claim because you hadn't informed them.

They also would not pay out if the silly electronic handbrake did not work

vehicle must be roadworthy blah blah blah

A working handbrake is better than a non working one

Now this could be an option for me too. Have you any idea of the bits needed? Did you have to fit another centre tray too?

Thanks

11th March 2013, 09:11 PM
yes had to fit centre tray. and replaced electric park brake pull out handle with one from a manual hand brake, the garage got all the parts, they must have remove the electric brake from cars memory to prevent errors on dashboard. I have since mot car and had no problems. I think any good garage could do this just go to a breakers yard ask for all the parts for manual brake I hope this helps I am very satisfied. from ballybeen

do u no of any other garages doing this..charkes hurst put my car on the machine yesterday an came up with the handbreak computer had gone!! 607 for the part alone. i dont understand y it just cant b reprogrammed?? i very much like the idea of a manual handbreak then all i have to worry bout wud b replacing cables..

13th March 2013, 08:25 PM
Viki, I think this kind of conversion will only be undertaken by a smaller local garage and may be even need to be a Reno specialist. I think a Reno dealer would refuse point blank to undertake such work. I don't know where you are but here in Yorkshire I struggle to get any local garages to actually work on my Scenic. What I can say is that the diagnostic machines may not alway's give the correct answer. I've read a few threads on this forum about the Parking Brake, there basically seems to be any number of things wrong with the braking system that can flag up this error. I've heard of people changing the car battery because it was getting end of life and also heard of people giving the rear brakes a good service. The rear calipers tend to stick which throws the error up. I personally think that it has something to do with the cold temperatures as well.
I'm personally waiting for the weather to warm up a bit and then investigate further. I'm starting to think that the cost of the parking brake unit fitting is getting to the point that the car isn't worth repairing.

So don't go jumping in straight away and have the main unit replaced as there may be something else that needs repairing first.

Best of luck, I think we all need it with these cars.

I do not know of any other garages. that does this. I booked it in to get handbrake checked, they told me the motor was done, and offered to install a manual brake, it was the first I knew this could be done.

I have to get this sorted asap my MOT is up next week an with the light on it's a fail straight away. I no a fella who works for Renault said the warning lights wud go out but come staight bk on again. Ballybeen could u send me the number if the garage u got ur call done I'm very interested but can't find any garages tht ur talking bout. I can get a sec hand one for 250 but whose to say it won't go again. This has been a nightmare to get sorted. I live in Belfast an
If a manual handbreak is another way I'd def b driving to Newcastle

14th March 2013, 08:29 PM
Best of luck Viki, I really feel for you with such a lack of time. Just out of interest I've not had a clear answer from two local garages about the warning message being a fail. Vibes I'm getting is that if the parking brake works and the normal brakes are working too the message shouldn't be part of the test.
Mines booked in over Easter week so I'll see what that brings.

So all being well I'm being changed to a manual handbreak. Renault should certainly look into this fault in the handbreak as the longer it's left gods knows what kind if accidents this will cause.

Just had this issue with my Scenic this evening in the freezing cold where I parked up to pick the mrs up from work.

Started engine and parking warning to check brake and it wouldn't let me pull away so was jammed on! Luckily I knew from past problems with this french piece of crap where to find the emergency release!

Got it home and did a search on here and found the above which worked first time.

So a big thanks to the poster as it's saved me some grief.

I both love and hate this forum. Love it for the useful advice as it's saved me literally thousands in the 3 or so years Ive had this car, but hate it given the fact how much information is on an independent forum about the problems this marque has!

I don't think there's another forum that has this much information on the internet!

Does anyone have any idea why this actually happens or did I miss it in the thread?

This is twice in a week and both times I'd parked up, switched off the engine and was in the car waiting on the wife at work first time, second time I was at the tip getting rid of garden waste. Went to start engine and the warning comes up and the handbrake wouldnt release!

3rd April 2013, 01:39 PM
YAAAAAAYYYYYY WOOOHOOOO mines fixed!!!!!:d

The garage put it on the fault reader and it had 5 faults logged for low voltage!!!!!

It's crazy it starts on the button no problem at all and nothing else that would point towards the battery being goosed. Anyway new battery and fault logs cleared, I suppose nearly 8 years isn't that bad for a battery to last.

Just waiting for a new drive shaft to arrive now:mad: that flipping car is a money pit.

I would suggest get your fault codes read and see if yours is the battery too. Think about it the cold weather kills batteries doesn't it.

Hiya all this is my first post..

Ive been reading the threads to on this issue.

I kinda have the same prob on my Espace 2004.
But my parking break is still workin (at the momment!!!).

But I also have a ticking sound from under the car after a few mins after ignition is off, not sure at all what this is?
My warning light on the dash is also telling me there is a brake fault!!!:crazy:

so we r in the same creek, but diffrent boat!!!

Sounds like a garage job..:eek::eek:.

Unless anybody can shine any light on this for me!!!

Hmmm it's not nice when you are stuck like this is it. First of all is your error message "Brake Fault" or "Parking Brake"? they are two different things. Mine was the "Check Parking Brake" message, the parking brake still worked fine. I was fortunate that it was a low battery that caused it. My advice is get the errors read. If it's a "Brake Error" then this may be a safety issue so needs sorting urgently.

well checked the car using the code reader I got off ebay and theres not codes stored, did that 2 days ago and guess what, yesterday it bloody did it again :-(

Just to be clear, I get the warning about the parking brake and it actually jams on, im not getting a warning but still able to use it as i have to then climb out of the car and release the handbrake using the emergency release in the boot! :crazy::crazy::crazy:

As far as I'm aware it's only the really expensive readers that will read brake errors. May be your just needs brakes stripping down and cleaning. The caliper could be sticking. I've heard of the cables themselves sticking too.
Careful using the emergency release in the boot, I'm sure I've read on here somewhere that the brakes need resetting when this has been used.

Yeah, Im at a point were Im going to have to have a look at the rear brakes and cables to see if thats the issue :(
Wouldnt mind but the mot didnt mention anything about the wear on the rear brakes so Im not sure it'll be wear but you never know.

DonnieP
20th April 2013, 02:48 PM
right I've just had both wheels off to look at the discs and pads and all are well within the specified limits which I thought they would be given I did them about a year ago.

So then Im thinking what else could it be and remember someone saying about the cables, so I had the rear of the car jacked up with handbrake off and both hubs could be spun, checked with handbrake on and both are locked. so that works.

So, I released the emergency cable in the boot which would release the rear brake, which it did and that's when I noticed a difference in the two sides.

One caliper, in the handbrake off position, the cable end stop wasn't even touching the actuating arm and you could pull it in and out and could tell it was moving in the outer cable, but ....

http://i33.tinypic.com/o05mir.jpg

is the picture of the driver side, with the brake off and able to spin the wheel, but you couldn't pull the inner away any farther.

So, now Im wondering if it's something sticking in the driver side cable?

Grand Scenic 1.6 2004
PARKING BRAKE FAULT ERROR MESSAGE. There are various reasons for this message and I think mine was one of the easy ones to resolve. I had PARKING BRAKE FAULT ERROR MESSAGE when I started the car followed a few moments later with CHECK PARKING BRAKE. I replaced the pads front and rear and this did not solve the problem.
I had a Diagnostic check carried out by Renault dealer which showed the hand brake switch faulty. I went to my local breakers and bought a switch for 20 and fitted it, this solved the problem and cleared the error message without going back to the dealer.
From my experience I would suggest buying a switch from a breakers for 20 and fitting it yourself before doing anything else to see if that is what is causing the problem.
It is a shot in the dark I know but 20 is better than spending a lot more money if that is the problem.
To change the switch is very easy, you remove the switch cluster under the switch with a screwdriver or paint scraper then remove the two screws holding the switch in place and pull forward then remove cable attached to the switch and then replace switch.
I hope this a help in solving the PARKING BRAKE FAULT ERROR MESSAGE.
I have include photos showing step by step removal.
I have not seen mention of the switch fault in any of the previous posts
