FAQ for Brake Booster Repair

Q: What will happen when an out-of-specification bore could result in a fracture of the relief valve 0-ring seal within the module?
A:
If this happens, during braking applications the driver may be able to hear an engine compartment noise similar to the sound that occurs when the steering wheel is turned to a full stop position. The driver could also experience a slight increase in steering efforts while braking and parking. Under certain driving conditions, a fractured seal may require a slight increase in the applied brake pedal effort to achieve the same vehicle deceleration rate as before the seal fracture. If this were to occur, it could result in a vehicle crash without prior warning.
