I have a 1999.5 New Jetta TDI with ABS which I recently took in to a dealer for the 80K mile service. They had to replace the rear brake pads and rotors. No surprise there. But now I have an intermittent problem with what feels like the brakes grabbing. I thought it felt like a sticky caliper and took it back to the dealer. They checked it out and didn't find any problems. They said they took it for a drive, but owing to the intermittent nature of the problem, they didn't see any problem.
Most of the time, the peddle goes half way down to stop the car. However, when the problem with the grabbing starts, I barely have to tap the peddle for it to stop dramatically. If I stomp on the peddle a few times, the problem seems to subside.
Given that they put new fluid in, could this be a problem of air in the system? Could the master cylinder be going? Has anyone else encountered these symptoms?
Thanks
David
