Brake discs warped AGAIN !!!!!!!

Yep; of all the possible ways of providing a handbrake, that was probably the daftest :-)

Chris Whelan (Chris Whelan ) gurgled happily, sounding much like they were saying:

Not at all. There's a VERY sound reason why the handbrake can't go on the rears on a FWD hydraulically suspended Citroen.

As the suspension sinks and rises, the wheelbase lengthens and shortens, due to the action of the rear suspension.

What do you think will happen in that instance, if the front wheels are locked because the car's been left in gear AND the rear wheels are locked because the handbrake's firmly applied?

Err sod all in reality. The same as if you parked with rear wheels touching the kerb.

Presumably the same caliper and brake pads are used for the handbrake as for the foot brake.

Do we know for a fact that such cars don't suffer from disc warping?

The Xantia (and, probably, the CX) had the same arrangement. The handbrake on these cars is very much an emergency brake - the handbook emphasises this - so having it acting on the front wheels is A Good Thing. The Citroen footbrake is quite unlike any conventional servo-assisted system in that any failure tends to be a total failure. I found this out one day when I tried rolling a Xantia a short distance on a hill without starting the engine. It was all fine until I tried to stop using the footbrake ...

Some do, some don't.

Lemme think - 70k miles in my last CX (separate handbrake pads), 80k miles in the XM (main pads used)...

David A Stocks ("David A Stocks" ) gurgled happily, sounding much like they were saying:

All hydraulically suspended Citroens have had front handbrake. I have a feeling the C6 and new C5 _may_ have moved it to the back, though, same as they've moved the brakes to DOT fluid...
