Hi:
I have a 2005 Passat TDI which I recently purchased and drove from Quebec to Ontario. I also drove it for another 2 weeks prior to performing some major work on the vehicle. So far I changed the Timing Belt, Camshaft and Drive Axels ... I even painted the drivers side front fender.
Anyway, my latest concern is that after starting the car for the first time, the brake pedal comes up quite firm, but slowly sinks ... right to the bottom!
Funny thing is that I did nothing at all to the brakes.
Even when changing the CV shafts, the calipers were simply hung on the side. Installing back over the rotor was the expected snug fit as they were not moved at all during CV shaft replacement.
Well, I've searched the net and some say this is normal operation for my car (HUH ?) and others say the master cylinder needs replacing (sigh - I'm getting sick of working on this car!).
I don't understand ... I did not notice this condition prior to my repair activities, none of which had anything to do with brakes.
One final point, the pedal does not sink when the engine is off ... no matter how hard I push. However, when the engine is running - SSSSSSSsssssink..... %&#!&*$ !
