B2 Brake Problems

My brakes are acting up. When I apply the brakes it sounds like a blast of air coming from the pedal and the motor revs slightly. No visible leaks anywhere.


What do you think? Brake booster, master cylinder, vacuum line?

Do you have cruise control? It sounds as though the cruise control servo is dumping air pressure, but the system isn't getting the signal to stop adding more air. Check your brake lights to make sure they're working properly. The leads on the brake pedal switch tend to break internally (invisibly) due to flexing. This switch controls the cruise control and brake lights.

Sounds like a vacuum leak in the power brakes. Disconnect and plug the hose and see if it goes away.

No cruise control. I don't hear any noise from around the booster/master cylinder when the brakes are applied. Only inside the vehicle.

Disconnect the hose from the booster to the motor? If it stops the hose and plug need replaced?

If you disconnect it and plug it and the noise stops I would suspect it.

Turned out to be a bad booster. A $70 part and it's good as new.
