Why does my Subaru Legacy shake when I brake?

Why does my Subaru Legacy shake when I brake?

Rotors. The number one reason that your Legacy’s steering wheel will shake is warped brake rotors. Rotors can warp if they’ve been worn too low, or worn unevenly. Warped rotors are even more common today than they used to be.

Why do my brakes vibrate when stopping?

The most likely reason that you feel vibrations through the brake pedal is because a brake rotor — the rotating disc that the brake pads are pressed against by the calipers to slow the wheel — is unevenly worn, or what some call “warped.” (It’s unlikely that a rotor could truly be warped from normal use as opposed to a …

Why does my steering wheel shake when I brake at high speeds?

Many motorists have experienced this problem: The steering wheel starts shaking when brakes are applied at high speed.

This change in the brake force causes the steering wheel to shake when brakes are applied.

Why does my Subaru shake at high speeds?

Shaking at Highway Speeds: Tire and Wheel Problems At lower speeds, you may not notice that your wheels and tires are slightly out of round. However, as your speed increases, your steering wheel may begin to shake. Replacing your tires may be necessary.

Why does my car stutter when I brake?

Brake shudder is the vibration that you feel through the steering wheel when you hit the brakes. If your brake discs are unevenly worn the brake pads come in contact with the flat spots present in the rotor’s surface which causes the vibration that we call brake shudder.

Stopping happens when you step on the brake pedal, which causes calipers (a little like the ones on your bicycle) to clamp down on the rotor to slow and then stop it. Inspect your brakes regularly. It’s easy and worthwhile. Replace disc brake pads yourself and save money.

Can a bad ball joint cause shaking when braking?
