Clean up the caliper of loose dirt Alfa156
Push/pull/lever pads to retract piston. If you are changing the discs, then a little brute force with a wide screw driver will probably not come amiss, but if you are keeping the discs, you may want to be a little more careful. Pushing the piston back will displace the brake fluid, so it has to go somewhere. You can loosen the bleed nipple to do this (make sure brake fluid is caught through pipe or clean rags). KEEP BRAKE FLUID AWAY FROM PAINTWORK. Tighten bleed nipple after to avoid air getting in. Alternative is to push fluid back into system but check level in master cylinder and take action if gets too high. If this proves difficult, wait until caliper is off. You can then use a G-clamp or similar, or like me, just use the narrow wooden handle of a hammer.
