Steering wheels are the last thing you want to feel shaking under your hands, no matter what the circumstances. If you feel yours quivering while you are on the road, chances are this would be followed by something going seriously wrong with the car, which could end up inconveniencing or endangering everybody in it. The following article contains some common reasons why steering wheel motion could be occurring. Regardless of what turns up as your specific problem, stick with a guaranteed professional service and you should be fine.
Worn Brake Pads
Whenever you push on the brake pedal, it sets off a sequence of rapid events: a caliper puts pressure on the pad, and this in turn presses down on the rotors. As long as each component works adequately well, your car comes to a halt, or simply slows if that is the desired action. However, if the brake pad has a problem where it cannot grip the rotors as well as it should, it can cause the steering wheel to shudder every now and then. The best approach is to get the pads and rotors checked, and if they are not up to snuff, replace them with some quality options.
Dry Guide Pins
The guide pins belong in the brake calipers and are responsible for guiding the brake pads’ motion towards the rotor. To be effective, these require periodic lubrication and cleaning. A dry or corroded guide pin can cause the caliper to become stuck, which is obviously bad. Another thing that could happen is the brake pads pressing down on the rotor from the wrong angle. In both cases, you would normally experience the wheel shuddering. Here, your best way forward involves getting the brake caliper checked by an expert, and deciding your next step based on the information they provide to you.
If the brake pedal pulses or the steering wheel wobbles while slowing the car, there may be trouble brewing with your brake rotors. The latter are prone to friction wear from the brake pads pressing down on them. This wear would cause warping and unevenness as time goes on, which means your brake pads could be pressing down on a rough surface. The steering could wobble as a result. You could get a technician to feel or measure the rotors for irregularities. If it is already at minimum thickness specification, then resurfacing is no longer an option; you would need a replacement after checking the vehicle manufacturer standards.
