The Brake System Power Assist May Fail
Brakes, February 7, 2013
RepairPal Expert Overview
Our Quick Take:
X5 Vehicles with an 8 cylinder engine are being recalled because power assistance for the braking system could be lost unexpectedly.
What Should You Do?
BMW will notify owners of affected vehicles beginning in February, 2013. Braking performance could be compromised or there may be no symptoms related to this recall. If don't receive notification and you feel you should have, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
All modern vehicles use some type of power assist for the braking system. The 8 cylinder models being recalled use a vacuum pump, connected to the power booster by a vacuum hose, to provide the necessary assist. The vacuum pump may leak a small amount of lubricating oil into the vacuum hose and this contamination could result in a loss of power assist, leading to increased stopping distances. Dealers will correct this concern by replacing the brake vacuum line with an improved version.
