In the next week or two I'm going to be changing the rear disks and pads on my 1999 2.0DI. After reading a few posts it became clear that either the bleed nipple needs to be opened prior to 'resetting' the piston OR the cap of the reservoir needs to come off?
Which one is it? Or would either do the trick?
Also have heard people talking about the piston resetting tool, I don't want to start a g/f clamp VS piston resetting tool VS pliers VS god argument. Just want to know if the piston resetting tool actually 'twists' the piston back into place as hard to tell from photos I've found on the net. and whether this can be acheived using any other means....this does sound like stage for arguments!
