I have an mk2 GTI and everytime I press on they work well but when I keep them pressed in when I loose brake pressure then the car start creaping. For example when I come to a stop light, after I stop I feel th brake pedal loose pressure and the car starts moving forward slightly....

Thanks

If the pedal slowly moves to the floor... it sounds like you have a bad master cylinder.

Cool thanks... I guess the 22mm MC will take care of that. http://****************.com/smile/emthup.gif http://****************.com/smile/emthup.gif

There is a check valve in the master cylinder that allows the fluid to return to the MC when you let off the brakes but seals off the passage to allow pressure to build up when you hit the pedal. If this valve doesn't close completely (a little dirt or gummed up) then it will bleed off the pressure as you describe. Other cars have MC rebuild kits, I've not seen them for VW, so you have to replace whole cylinder to correct the prob.
