Audi 100 Brake Bomb ?
My Audi 100 sometimes has the red warning lamp flash, and the audible warning as well, indicating a possible low operating pressure on the brake servo. The handbook says there are other things that can cause this warning as well, but I reckon it probably is low operating pressure, because, if after the light goes off, you pump the brake pedal a few times whilst driving, it comes on again.
Anyone know where I should start looking first. Pump, pipes, brake bomb ?
If it's the accumulator, anyone know how much they are and how easy it is to replace ?
