I posted just recently about my brake pedal becoming hard and the brakes binding after a short time. I have also been reading about the'bomb' Now Because I don't have a book I don't know where or what this is. I do have a canister maybe 10"long to the left of my master cylinder but I assume that's the power steering reservoir.
Now I trust the experience of the people who replied to my last post but I need to add some more detail just to convince myself that it's the master cylinder at fault.
Ok here goes.
1991 5cy 10 v ABSWhen starting out the brakes are good very progressive and the ABS light NOW comes on at 15mph. After maybe 4 5 miles the power of the car drops off as it struggles to fight the brake bind.
As previously suggested I tried cooling the master cylinder with cold water but this did not work. The brakes remain solid for some time at least until something has either cooled down or the pressure has dropped naturally.
In addition to this if I push the brake hard whilst not moving and cold the pedal goes to the floor with what seems a series of pulses...
I cleaned the calipers and new rotors and pads were fitted (all round)just before I got the car. Is there anything else which could cause these symptoms?
I guess I am looking for confirmation of the MC problem. This is my first Audi in the US having lived in England and I have no experience of brakes without Vacuum servo
