Why Does My Steering Wheel Shake When I Brake?

Why Does My Steering Wheel Shake When I Brake? Main Cause of Shaking Steering Wheel The main cause of shaking or shimmying of the steering wheel when braking is warped front brake rotors (also called brake discs). The vibration is caused by the brake pad making inconsistent contact with the rotor, sort of like a warped record spinning on a turntable.  Common Causes of Warped Brake Rotors Brake rotors can warp when they are heated up and then one portion becomes cooled at an uneven rate. A classic example of how this can occur is coming down a long hill or mountain, where repeated long braking is required, causing heat buildup in the rotors. Following this with braking to a stop, like at a stoplight, is where the problem occurs. The portion of the rotor that is clamped under the brake pads retains heat, while the exposed portion can freely dissipate it to the air. There are other circumstances under which rotors can warp, but the aforementioned describes the basic process. Con ... read more

BMW and MINI Cooling System Problems

Cooling System Problems, They’re Not Just for Summer. Lack of heat is often a sign that your BMW’s cooling system isn’t functioning properly. This can be the first sign that something is wrong. It isn’t always the gauge going into the red that signals this problem, lack of heat can, too. The heat generated by the engine warms the water and antifreeze mixture that cools the engine. This warm coolant flows into the heater core in the interior and is the source of warmth used for cabin heat. If there isn’t any heat, or the heat is weak, that indicates an issue with the vehicle’s cooling system. Since many MINI Coopers have neither a low coolant warning light nor a coolant gauge, this is often the only way to know that there is a problem with these cars. Be comfortable, and keep your MINI or BMW in safe operating order, call the Friendly Professionals ... read more
