Master cylinder.

Agree :smiley:

but why after being on lock, and whats the noise, (a knock like the other one who has the same fault)

Have you had your camblet done lately? What engine code do you have? I would bet 90% it Wont be master cylinder.
-
you might find that you have a damaged flexi hose when you put it on a lock hose kinks and forces fluid back up to master cylinder 1 st push on the pedal re primes the caliper and second push is fine

i have put the engine in(was a 2.0 8valve) and yeah i have done the cam belt why?

Ok not to worry then should be ok.
On a lot of mk4 platform cars there is a brake hose that runs alongside the plastic cover that you have to remove to do the cambelt. I have read lots of threads where people get there cambelt done and the garage bends the hose out of the way and forgets to bend it back where is should be resulting in intermittent brake failure untill the hose is bent back to where it should be. I dont know too much about this but as said i have read it a few times now. Apparently the master cylinders are bullet proof

Because when we changed Barry's brakes over he took his car to a normal backstreet garage to get his brakes bled. They couldnt do it blaming it on a knackered master cylinder. He rang round lots and lots of vag specialist garages and they all said that they are absolutely bullet proof and have never come across a knackered one and would put money on it not being the case, needless to say it wasnt it was just the fact the garage didnt no how to bleed the brakes properly.
Also im sure if this guys master cylinder was gone he wouldnt just have the problem a couple of times when on full lock like described

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.
