1. Warped Brake Discs: Worn or warped brake discs can cause the steering wheel to vibrate when the brakes are applied. If the vibration is accompanied by a pulsating feeling, it's likely that the brake discs are the culprit.
2. Brake Caliper Problems: A faulty or improperly functioning brake caliper can also cause vibrations in the steering wheel. Ensure that the brake calipers are properly lubricated and functioning smoothly.
3. Wheel Alignment: Improper wheel alignment can lead to vibrations in the steering wheel, especially at low speeds or when coming to a stop.
4. Driveline Issues: Problems with the driveshaft, universal joints, or CV joints can also transmit vibrations to the steering wheel. If the vibration persists even when the brakes are not applied, it's worth considering driveline components as a possible cause.
5. Engine Mount Problems: Worn or damaged engine mounts can allow excessive engine vibrations to be transmitted to the steering wheel. Inspect the engine mounts for any signs of wear or damage.
6. Power Steering Issues: Problems with the power steering pump or steering rack can also cause vibrations in the steering wheel. Check the power steering fluid level and condition, and ensure that the power steering system is functioning properly.
7. Tire Problems: Unbalanced or damaged tires can cause vibrations at certain speeds or when braking. Make sure that the tires are properly balanced and inflated to the recommended pressure.
Since you mentioned that the brakes were low and felt like pulsing, it's likely that the issue is related to the brakes or brake components. However, it's always a good idea to have a qualified mechanic inspect the vehicle to accurately diagnose the root cause of the vibration and recommend the necessary repairs.
