Hi, Florin.
Thank for the answer. I work technical director of car-care center of BMW in
Nizhni Novgorod. Our firm the official dealer of BMW.
I have the supreme automobile education. In service 11 years.
I have Audi v8. The machine very much is pleasant to me. With brakes this problem began recently.
I thought, that it is a bomb. I have replaced it. For some time the problem has disappeared. Then has appeared again.
I have replaced a forward part of the pump with pistons. All began to work normally. Now again the same problem.
By sharp pressing a pedal of a brake the pedal stops above and brakes are not present. ÀÂS works normally.
The pedal does not vibrate as at work ÀÂS, and under a foot the pulsation of a liquid is felt, and the same pulsation is transferred in
Steering wheel.
Now a problem in the information. I can not find the circuit and a principle of work of the hydraulic booster of brakes.
