## What is wrong

On certain vehicles, the relief valve o\-ring seal within the brake hydro\-boost module could fail.  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 slight increase in the applied brake pedal effort may be required to achieve the same vehicle deceleration rate as prior to the seal failure.  Correction:  Dealers will inspect the hydro\-boost module, and replace it, if necessary.
