Do you feel vibrations when braking?

Experiencing vibrations in your vehicle and steering wheel can be unsettling, especially during braking. If you notice vibrations while using the brakes, it is advisable to visit your nearest Tires Plus for brake service. Let's explore the possible reasons for your car shaking when braking.

First, unevenly worn brake pads or warped brake rotors can cause vibrations during braking. This can occur if the brake pads or rotors have worn down unevenly over time or have developed irregularities. Another possible cause is a misalignment in the brake calipers, which can result in uneven brake pad contact with the rotors.

In addition, a worn suspension system or damaged wheel bearings can contribute to vibrations when braking. If the suspension components or wheel bearings have worn out, they may not be able to properly absorb the forces generated during braking, leading to vibrations.

What causes a shaking sensation when braking?

When the wheel bearing is loose, it can cause excessive lateral runout since it serves as a mounting spot for the disc brake. This can result in a shaking sensation while braking. Additionally, worn suspension components can also be a potential cause for this issue, causing shaking to be felt in the steering wheel and/or brake pedal.

Why does my steering wheel vibrate when braking?

Steering wheel vibrations can commonly occur when there is a problem with the front rotors of a vehicle. On the other hand, if the rear rotors are experiencing any issues, the vibrations will be felt through the brake pedal. The reason behind these vibrations is the warping of brake rotors over time due to the heat generated from braking friction. Furthermore, uneven wearing of the rotor's exterior can also contribute to this problem.

Is there any uneven wear on your brake rotors?

Uneven wear of brake rotors can be caused by several factors, including warped rotors. When the rotors become warped, the wheels can turn out of the travel path, resulting in a dragging effect that may cause uneven wear of the tires.

Another cause of uneven wear is variation in disc thickness. This occurs when the rotors chew away at the brake pads as they make contact with the uneven spots on the rotor, causing the brake pads to wear unevenly.

Installing the wrong-sized brake pads or rotors on your vehicle can also contribute to uneven wear. Additionally, excessive wear on the guide pins or caliper can cause this problem.

To resolve this issue, you may need to replace your brake pads or rotors. In some cases, depending on the extent of the thickness variation, the rotors can be machined to correct the condition.
