Runout refers to a distortion of the rotor that causes it to wobble side-to-side as it rotates. Thickness variation, on the other hand, indicates the rotor is thicker in some spots than others. Both concerns can prevent the pads from pressing squarely against the rotor during brake application.

Why does my car wobble when I brake?

If you feel the shaking or vibration in your steering wheel and your brake pedal, it could be your rotors. The rotors get pressed by the brake pad to help slow your vehicle down, and if the rotors are out of balance, this could be causing the vibrating tremors that you feel in the pedal and steering wheel.

Why is my car shaking when I brake at high speeds?

Brake shudder is a vibration that is felt through the steering wheel, brake pedal, and suspension when the brakes are applied at high speeds. Brake shudder can be caused by a number of things including damaged rotors, malfunctioning calipers, or new brake pads that have not been properly broken in after replacement.

What causes front wheels to shake when braking?

This could be a sign of warped brake rotors. Your brake rotors are the smooth, flat surface that your brake pads press to slow or stop your movement. When your rotors become bent, the brake pads will press against an uneven surface when braking, which creates steering wheel shaking.

How do you tell if your rotors need resurfacing?

If your brake rotors have sufficient metal remaining with no hard spots, cracks, severe grooving or rusting, then the rotors could be resurfaced. Some have the opinion that unless the brake rotors have surface issues needing to be fixed, the rotors should not be resurfaced every time the pads are replaced.

What do warped brake rotors feel like?

Warped or excessively worn rotors may vibrate irregularly and cause vibrations that can be felt in the pedal, and sometimes through the vehicle's steering wheel or chassis. Additionally, the brake pedal may feel like it's pulsating when pressed due to warped brake rotors.

Why does my car shake when I go 70 mph?

The shaking is typical of a tire that is out of balance. Tires are balanced with metal weights. Over time, weights can come off. The other possible problem is that one of the tires is damaged and has a cord separation, which could cause the vibration and lead to a tire blowout.

How much does it cost for new brakes?

New brake costs can vary depending on the vehicle you drive. On average, a brake replacement can cost about $150 per axle. These costs can increase to around $300 per axle, depending on your vehicle's brake pad material.
