Delayed rear braking
My Citroen 2.1 TD XM VSX (N reg)has failed the MOT because the rear brakes have a delay. After working the brakes for a while they will start working. Has anybody experienced this?

Take the pads out, push the pistons back, make sure they aren't siezing then when you go for the retest put something heavy in the boot, a couple of sacks of sand should do it.
The rear brakes take their pressure from the rear suspension, most of the weight is over the front end so the rear brakes don't get a lot of use, this causes the pistons to stick a bit. Putting a bit of extra weight in the boot increases the ammount of brake pressure available.

Xantias..
all, my 1999 1.8i dives excessively on braking, my ABS 1.9 td 1994 doesnt.. it stays fairly flat..
why is this?
Both have fairly soft front ends, with new spheres in the 1.9 (although the ride in this car is still harsh compared to 1.8)

I think it'll remain a Citroen until the air in his rear brakes has been bled out. At which point it can be called a Citroen again!
Ahem.
Best way to bleed the rear brakes is to put the car in "High", and connect a long length* of clear hose to the bleed nipples. Put the other end back into the LHM tank. Now jam the footbrake on, and open the rear bleed nippes one at a time, and bleed lots (like several litres) of fluid through. You'll find after a fair while of normal fluid, there will be some air.
*a good source of a long length of clear hose is from a scrapped car that has a washer pipe going from a front mounted screenwash tank to the back window. Try an early 306.

Thanks for all your help, I will try this over the weekend and will let you know of the outcome.

Yep. No reason why not. The longer you leave it "bleeding" the better, as you circulate fresh fluid through the whole system.deian wrote:wow does that work? you can actually bleed from the brake niples back to the lhm resevoir?
I'll make one little addition to the process. Check what colour the first little bit of LHM is when it comes out, as if it's dirty, then you'll want to discard it. Once the LHM looks nice and clean, then put the line to the tank, and bleed away for as long as you can.
One of many, many places!Is that where haynes got it wrong?
