We have got a customers A4 here with some unusual problem. I will start from the start.
Car was recovered to us with 4 binding calipers and the clutch gone (we replaced this 6 months ago).
The clutch was burtnt out, looked pretty messy. we have now replaced this and are moving onto the brakes. We originally thought 4 calipers have siezed as the car sits and we have free'd off most the calipers before. Before we started we have tried bleeding the calipers, as soon as we opened the bleed nipples the calipers released.
Now we are starting to think maybe the master cylinder is sticking and causing hydrulic pressure build up in the lines but due to the nature of this car we are not 100% in this conclussion.
Has anyone else had a similar problem occour? Any help much appreciated.
