Shamelesly stealing the format from Gonescenile's Scenic pad replacement thread (http://www.renaultforums.co.uk/showt...ht=Scenic+Pads) here's one for the Espace IV as although the job is virtually identical, there are a few differences.

Ensure that the handbrake is off as per Gonescenile's method of pushing the button & pulling the handle as you remove the keycard. Chock the front wheels and jack up the rear end remembering to use axle stands where possible.

Pop the bonnet and remove the brake fluid resevoir cap:


I've always wrapped a rag around the thread of the filler neck as there is a possibility some may spill out when the brake pistons are pushed back in:


Remove the rear wheels, then remove the dust covers from the caliper bolts.


Unlike with the Scenic which has normal nuts & bolts on the caliper, Renault (in their infinite wisdom) decided to use long allen key bolts instead. To make matters worse they are 7mm (most allen key kits go from 1-6mm or even numbers between 2 & 10mm). I bought this key from alocal motor factors for about £3.


Here's a tip: this type of tool has quite a long shaft and the limited space behind the disc means you only get about quarter of a turn before having to re-position it. Take a hacksaw (or something like a Dremmel if you have one) and chop about an inch & a half off the shaft. Clean up the edges and you have an easier to use tool, but also more importantly, you can now pop the cut-off into a 7mm socket and use your socket wrench instead - much quicker.

Once you've undone the bolts the caliper should swing free - CAREFULL there are quite long metal brake lines on the Espace and if you're clumsy you could kink one. If the disc's are worn the caliper may need a little 'persuasion' to come free. Once free the pad on the outside of the disc will just fall free, but the one on the piston needs to be pulled out as it clips onto the piston. Once the pads are off it should look like this:


Like on the Scenic, these pistons wind back into the caliper. Friends in the trade told me that if you're carefull you can get it to turn using molegrips or something similar. B!*%@£ks to that, try and get the proper tool and it'll save a load of grief (trust me on this...). I borrowed this off a friend, but you can get from places like Machine Mart or Screwfix.


Wind the piston back as far as it will go, then clip on the new pad (you may need to bend the clips up on the new pad slightly to get them to grip the piston). The outer pad simply hooks onto the bracket and is secured when you re-fit the caliper. Position the caliper over the pad and tighten the 2 allen bolts again. If my guide makes any sense, it should look like this:


Pump the brakes to bring the pedal back up, refit the wheel and repeat on the other side. Check the fluid resevoir and top up as needed before replacing the cap.

These are the tools I used:


1) Clamp: 2) 7mm Allen key: 3) Pliers: 4) Adjustable Spanner: 5) Brake Piston Winder: 6) Socket driver, 7mm Sockett & offcut from Allen Key: 7) 10mm long socket & extender bar (used to give the Brake Piston Winder a bit more force): 8) 'Persuader'

Incidentally, don't let your pads wear down this much as it makes getting the piston back in an absolute ballache:

Excellent thread Scouse I will move it to the Espace knowledge base, I'm sure many Members will find this very useful.

Excellent post Scouse - just one other thing I would add.
When doing these type of pads I always remove the long allen keyed bolts (pillar bolts) make sure they are clean and free from dirt and gunge and give them a light smear of rubber grease. I agree the proper tool does a much better job but it can be pricey for the DIYer.:) I agree most allen key sets don't seem to contain a 7mm key but I was able to source a set for around a fiver from my local motor factors which contained both long and short keys.
As a general rule I always check the bleeder is free as it prevents it from seizing up - just in case you have to need it in the future.:)

As a matter of interest what was the G-clamp used for:confused:

It's what I normally use for pushing the piston back in. I ended up using it to clamp the plate on the of the piston winder to the outside of the caliper as the nearside pad was so worn their wasn't room to get the tool within the caliper body.
Lesson for the future - drive the wifes car more often so the brakes don't get into that state again....

Gee whizz - they must have been well worn mate - lucky the disks weren't damaged. I had a similar problem once but was able to coax the piston back just using a bit if force on the wind-back tool without the plate until I had enough clearance.:)

The rear calipers on the Espace are the same as the Lotus Elise (and a few other cars)! Have a look here ... http://wiki.seloc.org/a/Brembo_Caliper

Once you are used to them they are pretty good.

For a cheap (£10) wind back tool see EliseParts at ... http://www.eliseparts.com/shop/index.php?main_page=index&cPath=112_116

Or you can make one fairly easily. Just a piece of bar with two tapped holes with short set screws. Can remember the spacing but it is on one of the Elise boards somewhere.

Regards

Hate to say it but the Draper tool doesn't have the right pins / spacing. I bought one! Anyone want one cheap?

I also made my own using a bit of steel strip and two nuts and bolts. It was OK but you really need a piece of strip 5 or 6 mm thick so you can drill and tap it. The nuts meant they could flex in the strip and it wouldn't allow suficient purchase to get the first turns on the piston.

Hence I ended up buyimg one from Eliseparts

I ain't certain Bruce but I think there may be two options in the Draper range - if my memory serves me correctly (not what is used to be:d) I think my local motor factors stocked two models of the Draper tool.:)
But your idea of making one up is excellent and cheap into the bargain. I have actually witnessed guys using a pair of pointy nosed pliers and it working successfully.

renault grand espace rear pad rattle

hi, just a footnote to replacing rear pads on year 1999/2000 shape models with bembro calipers, some of these models had a terrible rattle or suspension like noise from the rear of the car, took me ages to pin it down to rear pad rattle!!
renault could not solve the problem locally[surprise surprise],fault is caused by no anti-rattle springs on pads!! new oem pads should now have 4 springs and split pins to go into top of pad,[check with ebc picture on pads number d885] this has completely cured the rattle!!
i informed local renault franchise garage who were unaware of problem or cure, their original pads had no clips listed on the parts list!! i guess oem suppliers had some feedback and found their own solution!!

Another option is to use the Elise trick.
Buy some PTFE stick on spacers and pack the TRAILING edge of the pad with these.
Again Eliseparts will supply them, the cost a few quid (about 3?)

Excellent post Scouse, thanks for the time you spent in putting that together. Any idea what the distance between the pins on the rewind tool is? I don't really want to buy a complete tool set, just the right one for the job. Many thanks.

I went to Elise and £10 quickly ramps up to £15 (£3 delivery and then VAT on the whole lot), so maybe following Bruce's advice to make one up is the best route.

Can anyone tell me if it rewinds clockwise or counter-clockwise (2007 Espace)?

I need the same answer if anyone can help, this time on a 2005 vehicle.

:guinness:Thanks for the info, anyone else attempting to undertake this on a grand espace please do not, under any circumstances be told that an alternative multi purpose brake piston wind back tool made by draper ( a cube with an 3/8" square ratchet drive is any good for it. I had to cut two of the lugs off from one side (the one with four lugs for it to fit the piston)) and i had to pay £ 9 for it.Basically go with the tool shown as per Scouse and save yourself bulging neck veins a plenty. thanks Scouse. Good man

Hallo,

Maybe it's my pc, but I don't see any pics. I have to replace the pads on my Espace and those pictures would be very helpful.
