e30ftw 396 Report post Posted January 10, 2014 I have an odd issue since changing brake boosters, After driving for about 15-20 minutes the brake pedal will go hard and it feels as if the car is being held back. It has stranded me twice on the motorway this week, Cruising at 100kmh then all of a sudden the car slows down and cannot accelerate. At first i thought it was the gearbox, but today it happened again and I noticed the pedal had gone hard before I reached the motorway - Then about 2km down, the steering wheel started shaking and the car came to a hault again. Sat there for an hour letting them cool and eventually i felt them unstick and avoided using pedal brakes until I got home. Only thing in the brakes I touched was the brake booster to a MK2 golf one which is a straight swap, Could the booster be bad since it seems to stop working after a while? Any ideas as to why it would cause the brakes to stick, or can the booster get stuck? The engine doesn't seem to idle weird or anything and it has the one way valve for vacuum from the intake manifold, and yes its the right way around Quote Share this post Link to post Share on other sites
