i am assuming it is the same procedure as an xl7. front rotors are replaced by pulling the wheels and removing the calipers. the rotor is easily removed. calipers are held in place by two bolts
Front rotors on Citroen relay are always replaced in pairs.
Remove the wheel, the calipers and the rotors, reverse procedure with new rotors.
My guess would be that you might have a bad brake hose to one of the front calipers.
pull off the front wheels. remove the calipers. remove the two screws that hold on the rotors. replace the rotors and reverse the procedure.
With the wheel off, remove the calipers, then the rotors just come off.
Are you asking about brake discs?A re't they slip off rotors? remove the front tires then the calipers then slip off the rotors.
It's rare....because usually the master cylinder will allow pressure to bleed off. Not the other way around. But if you have replaced the calipers, this is the next thing I would check. I suppose it could be sticking.
have you tried the proportioning valve. sometimes dirt will get in there and clog the returns.
If calipers were also replaced there has to be something else preventing the pads from backing off. If it was only one side I'd suspect the hose, if it's both I'd have a look at the master cylinder.
take brakes off and calipers off, next rotors should come off easily.
Pull the tires off and take the brake calipers off and the rotors will pull off.
