The problem
Certain motorhomes fail to comply with the requirements of federal motor vehicle safety standard no. 105, 'Hydraulic and electric brake systems,' and no. 135, "Passenger car brake systems." Some of these motorhomes were produced with an out-of-specification brake hydro-boost housing relief valve bore.
The risk
Consequently, the valve o-ring seal may fracture. Steering efforts may be slightly increased while braking or 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 prior to the seat fracture.
The fix
Gm is conducting the owner notification and remedy for this campaign. Dealers are to replace the hydro-boost relief valve. Owners should contact gmc at 1-866-996-9463; or four winds at 937-295-2983.
