I FOUND PROBLEM, i could not belive it when i saw it, i got chance to get it up on ramp with someone lock to locking it, it is the calaper(bolt on the pipe) hitting my anti roll bar drop link bolt, there for pushing the piston back.this is because i fitted ajustable drop links as my car it quite low and the drivers drive shaft used to hit the antiroll bar, im going to try a get some steering rack restrictors or shorter track rod arms, anyone know if these are made for the mk4, i know they used to be fitted to a ford ka if a the genuine ford bodykit was fitted to stop the wheels from scuffing.
