    Default changing discs and pads, pushing pistons back.....

    couple of questions regarding changing discs and pads all round.

    i have done it on a few cars now with no issues, and plan on renewing them on our new 'c', having read some guys on the internet they mention winding the pistons back, is this just the rears and is related to the handbrake, or do the fronts need to be wound in too?

    also, some guides say, unscrew the reservoir cap, and push the pistons in, but then others have said not to do this as you can brake something in the master cylinder, instead, you need to bleed out the fluid from the caliper itself.

    whats the correct way?

    The rears only for winding back bud some use long nose pliers others have the tool for the job, I have always jst unscrewed the cap when pushing the piston back but there are mechanics on here who should have more of a clue.

    The fronts can be pushed back in as normal, only the rears need to be wound back in.

    The best method is to slacken the bleed nipple and then push the piston in, this also helps keep any contamination out of the system.

    I got a cheap windback tool from halfrauds for about 15 quid, and it's handy for pushing the fronts in too, easier than using a long bar and a lot of welly.

    Default

    I always open the nipple and push the piston back by hand on the front. It will move backwards really easily.

    If you don't open the nipple and just force the calliper back, you run the risk of the master cylinder seals flipping round and getting damaged.
