Brake caliper problem....Possibly a silly question

[ad.]

Hi all

I tried changing the rear pads and discs on my car just now but I cant get the caliper piston to compress so there is enough room to fit new ones. Ordinarily (never done it to a VAG car but on others) a G clamp is enough to press the piston back giving enough room for the new pads and discs (Obviously thicker than the knackered ones) but I cant for the life of me get the piston to press in. Obviously the brakes and hand brake are off. Is there something I need to do to re set the caliper? Perhaps something to do with the handbrake?

You need a caliper windback tool which actually turns the piston as it goes back into the caliper.

Ah ha!

I did wonder that as the piston has two notches in its outer ring. I guess these are available from Seat?

From Seat or any good car accessory/tool shop near you.
