Megane Rear Brake Discs - how too

TIME: around 1.5hrs.
PARTS: 1 set of brake pads, I pair of Renault rear discs, with ABS ring and bearing, 1 sachet of anti squeel paste. some locktight.
TOOLS: Thin flat chisel, hammer, 27mm (I think size almost worn off now) socket, 13mm socket, large knuckle bar, 3/4 ratchet, 16mm open end spanner, wire brush, torq wrench oh and piston turning tool, in my case a VW one. Anti Squeel paste.
Simple job really would have taken photos but wife had taken digi to work to photograph shop move around!
1 -Chock wheels and remove hand brake
2 - Jack and axel stand car, remove road wheel.
3 - Use flat chisel to tap off hub cover for wheel bearing hub nut, use large bar and 27mm socket, loosen nut on stub axel.
4 - On the back of caliper disconrct hand brake cable and move out of way, quite simple just pull on cable to get it out then
push it down through the slot, cable off!
5 - Use 13mm socket and you will also need 16mm open end spanner to remove the caliper slider bolts, quite tight as locktight will have bee nused once on the move fine, the 16mm is used to hold the slider pins whilst you undo the 13mm bolts on the back of the caliper.
6 - Remove claiper and rest on rear suspension arm.
7 - Remove pads.
8 - Now remove caliper hanger, you may notice they are on star bolts, MMmmm I used a HEX socket (13mm) I don't think a star (multi hex) socket will work, they are really tight to start with, again been put in with locktight, use the large knuckle bar for more leverage, once you have broken the locktight seal they come out ok, remove this hanger.
9 - Now back to the large nut, undo this all the way the Disc will then just pull off, they are loose once the nut is slackened.
10 - Now push in the caliper piston, this can only be done using a caliper retraction tool, as you have to wind them in, remember to remove the cap off the brake fluid resovior 1st, postion the tool and wind in the piston. Fully in.
One side was quite tight on mine so I had to put he hanger back on the bolt the caliper to the hanger again to get the piston moving. they where not the easiest of things to wind in.
~~~~ you are now ready to reassemble ~~~
1 - pull out the pins from the hanger and coat with copper grease, push them in and make sure the rubber bellows are back in place.
2 - clean and apply a little grease to the sub axel, DO NOT allow any dirt to be stuck on here, then push on disc, again make sure there is no dirt on the nut, then wind nut on and torq up.
3 - apply some locktight to the tips of the hanger Star bolts, postion hanger and wind in bolts, torq up.
4 - put your new pads in and check caliper fits over them.
5 - coat caliper piston and outside fingers with anti squeel paste, postion caliper over pads, you will have some spring presure here from the pad springs, so you will need to drip some locktight on the caliper bolts 1st and keepthem to hand, push in top of claiper and start one of the 13mm caliper bolts, once on a few turns, move to the lower one, push caliper in and start lower bolt, you can now using the 16mm open spaner and 13mm socket tighten up the caliper slide bolts.
6 - Almost there - you now need to pull the hand brake cable through the slot and re-attach it to the rear of the claiper, this can be done by hand easily, once this is attached, job done!!!
Now just open car door and operate the hand brake leaver to take up the slack, once you get a decent hand brake, pump the foot pedal a few times as well just to get that pedal back.
Leave hand brake off, try moving the disc should be ok, replace road wheel, drop car, do the other side. remember to do the hand brake and pedal thing for that side as well.
I used Genuine Renault rear discs as I have heard a few stories about aftermarket ones putting on ABS lights even when they have the ABS ring attached, also beware the discs with no bearing, bearings cost around 50 per side, and need to be pressed in is the saving on the disc price worth this, the ABS ring looks like it is coated in rubber so I don't think you can actually remove it and if you do I am almost sure you can not get it to stay in place on the new disc.
You don't have to use Renault pads.
Yes the Renault rear discs are a bit pricey, but at least it makes this a simple one time job which requires a speacial disc, non Reanault ones will cost you around 90, a lot of places will not return them once you have tried to fit them especailly from a DIYer, you need to ask the question directly, "if this disc puts my ABS light on after fitment can I get a refund" and see what they say, I have seen two differant sellers on ebay none of them replied to this question, the local motor factor told me once fitted no refund, as the parts can not be re sold, yet you need to fit them to see if they do work.
I am not saying they all don't work, for some reason some do, I know of a couple of people who have bought these cheap disc kits and they worked fine, but also know of at least 3 people who have had to resell on ebay , along with all the hassel that goes with it when the person mails them back to complain their ABS light is on.
All said now.
The actuall job of changing them is simple.
Hope this helps you save some cash.

Re: Megane Rear Brake Discss - how too

I have just done this on a 2003 hatchback.
The hub nut was 30mm and the external torx bolts that hold the hub carrier are E16.

The hub nut torque is 280Nm, which is pretty tight.
The caliper bolts are 36Nm
The caliper holder bolts are 105Nm

I used non Renault parts. The discs were complete with bearing and ABS ring and each came with a new hub nut and dust cover. You should always use a new hub nut. The pads came with new bolts to hold the caliper on.

Thumbs up Re: Megane Rear Brake Discss - how too

A very good write up on procedure

I would recommend fitting new nuts , as I believe they are one use Nyloc.
I replaced rear discs in september and the nuts were about 3 a piece total cost for discs and parts were about 152 parts from Renault dealer

Re: Megane Rear Brake Discss - how too

I used non Renault parts
Hi Neil, just spotted this, I take it the non Renault parts did not put on your ABS light, strange isn't it how some cars it does others it does not, over the past 12 months we must have done in the workshop around 8 rear disc changes now the first 6 we used motor factors but at least 4 went back with ABS light on, one set, one of lads took home for his own hatch decided to ignor the ABS light, fitted them and it didn't put it on how strange is that, so we are now wondering if it is the cars pickup ring which is twitchy, not the disc ring, yet the genuine discs we never get a problem with.
Heck of a lot cheaper if you can get away with it, all I will say is make sure the discs you are looking at do have the ring, it is possible to remove the ring and put it on the new disc without braking the ring but rarely sucessful in operation, apparantly you can warm them up with a heat gun to expand them move them over quickly and let them contract, they very rare grip after, although the discs are many pounds cheaper without the ring personally I don't think it is worth the hassel. the chances of it working are VERY low.
