Brake Piston Wont reset

Its in the rear of a 2002 t1.8 I have tried the whol c-clamp method and everything....What do I do!

Technically you are supposed to by a new caliper, pushing it back in can cause tears in the seals and definetly shorten the life of the caliper. but if you still wanna push it in you should take the brake line off the back so the fluid has somewhere to go but then you'd have to blead the brakes, otherwise just c-clamp the shit out of it, sometimes they are really tight in there.

i have done rear brakes on a vw yet but usually rear pistons have to be turned or screwed back in and remove the cover from the resovoir.

You need a calliper reset tool.  These callipers screw out as your brakes wear down, the reset tool pushes them back in but when you turn the reset tool it applies pressure just as a C-clamp does but it also will turn the piston as well scewing it back in.  Look at the piston on the calliper and you'll see that there are two notches and that is where the reset tool fits into the piston and turns the calliper.  Good luck!!

yea .. just put pressure on the caliper with a c-clamp and use channelocks to turn the piston as you keep applying pressure...  thats the cheap way to do it.. dont damage the piston boot.. or just go get a 3/8 drive , extension, and the square tool to compress that caliper
