I wonder if any of you guys can assist with the following issue with my '01 Passat TDi130 Sport Tiptronic on 175K miles.
3 weeks ago I pulled up smartly (didn't activate ABS) and on releasing pedal it didn't come up and brakes were locked on. Had to get car AAd to garage, supposedly a reliable non-franchise rather than the local VW plateglass emporium. After some messing and calls to VW diagnosed a faulty master cylinder and changed it for a genuine VW unit for £350!
I picked car up and immediately noticed pedal was higher but as brakes worked didn't worry too much. However, earlier this week after 15 miles of dual carriageway speeds the car started to shudder and needed more power to maintain speed. Pulled up suspecting a flat and greeted by very hot brake smell, clearly brakes binding.
This has persisted intermittently since. I have had wheels off and found by releasing a bit of fluid at the bleeds the brakes ease so system seems to be holding pressure after pedal is released. I have found this only on NSF wheel and OSR.
I read another post with similar problem where servo was replaced. I'm now worried that wrong work was done and maybe I need a servo as well, that given diagonal nature of problem, could it be the ABS pump (vast £s) and how do I get a reliable fix, ideally without darkening the doors of VW. garage who did master cyl is already making negative noises and he's not even had the car back yet!
Any advice would be very welcome.
