Rear Brakes

[Guest C5buff]

With regard to the corrosion between stainless and aluminium. It does take place but because the materials are a closer match it is much reduced and as I said in a previous post I intend to remove them as part of my serviceing every 12000 miles to check them.

I've just done the rear brakes on my 01 2.2nd. No way could I re use the old callipers. The fuzz up was so bad that the callipers had tipped back away from the disk so far that the disk didn't touch the front of the pads. This left a ridge of pad that came together and stopped them working. This in turn starts to force the pads out of the callipers and had broken the hoop of calliper the pad retaining bolt goes through. I couldn't see it being long befor an epic fail took place.

I got new rear callipers for £80 a pair and a full set of disks and pads for £112 of flee bay. My breaks are will good now. Thank you all for contributing info to this thread. I wouldn't have even looked at the back breaks if I hadn't read this thread first as I thought they were ok. So you may have saved me an mot fail or worse.

There is also a pinned note on doing the rear brakes that is worth a look. A bit of copper grease should be used in the pad retaining bolt holes on the caliper to help prevent it corroding away. If the rear pads are now a bit loose (Citroen changed the design) and clunk when the brakes are first applied, Citroen now supply a new shim to go on the pads held by the spring - this can be seen on the Citroen parts diagrams for the rear brakes.

I fitted new discs and pads to my C5, a 2005 model last weekend. I was surprised at how little corrosion there was between the calipers and the arms. All they needed was a quick scrape and another coating of copper grease. Having had Xantias and a BX, and trouble with removing the bolts, in the C5's first year, I removed the caliper bolts and coated them with copper grease, consequently now I never have any trouble with them when doing the brakes.

The manual talks about injecting thread sealant through an opening in the side of the mounting hole .No wonder it seizes

Yes! I can't see any reason for that. As I previously said, I removed my bolts in the car's first year, cleaned up the shanks and coated them with copper grease. Now they are easily removed and from one service to the next, never show any signs of loosening.

The rear calipers were replaced on our 2002 HDI due to peculiar brake pad wear. The local Citroen Indy fitted two new calipers from Citroen and all in an afternoon, despite warnings about the possibility of shearing the bolts.
