Compensators, Are There 2 For 1.9

[Rafe Dent 0]

Just got back from the MOT (CT over here) and the brake (im)balance on the rears came out at 31%.

I've changed the discs and pads all round very recently (garage job, so should be OK). So would that be the compensator? Are there 2, and do I just change one of them (the one on the low side presumably)?

Done a search, saw a great photo but couldn't quite see into the nitty-gritty - fuel tank was hiding it.

Thanks in advance, Rafe

There are two yes (left and right). Mine failed on the rears a little while ago and I changed the compensators but to no avail. Turned out to be a duff caliper.

As one side is 95 and the other is 65, I would change the first one as it is probably just not compensating anything.

 

Had this with a friend´s car two weeks ago. The readings were 126 to 62.

 

An easy way to determine which one to change is to watch if one of the rear wheels locks up under braking.

 

Given an otherwise working brake system, the side that locks up will be the side to have the compensator changed.

Thanks. And for the correction to change the high one - obvious really.

Will also try and take some photos to update this one, which unless I'm being a bit of a plonker, only shows one (?)

yeah there's only one (1.9 compensator) in that pic and appears to be the rear right one .

 

the other one is on the other side .

but the compensators do not effect braking ability ? Are't they there to stop the brakes locking up, and not actually assist braking. I'd assume you either have air i nthe system or your calipers are not working too well.

One of mine failed years ago. Peugeot failed my car at the MOT and suggested that they replaced the caliper.

I told them to FO and had a look at it myself. Couldn't get any fluid out of the bleed nipple - removed caliper stood on pedal nothing came out.

Hence this was how I discovered the compensator had failed.

Yes they do. They just limit the amount of fluid going to the rears vs the front. It's basically a spring and ball system inside. The spring pushes the ball so the brakepressure is limited. Now what happens when these things get older is that the ball rusts and gets stuck...result: full pressure of the MBC on the rear caliper. Quite dangerous when you need to make an emergency stop.
