Why My Car Rocks Back and Forth When Braking

February 15, 2024

When a car rocks back and forth when braking it is often due to uneven wear of the brake pads and rotors. A brake repair shop can fix this issue so you can drive safely and smoothly again.

The Brake Pads are the'shoes' that your tires grind against to stop your vehicle. When you brake the car's weight shifts forward and causes the front suspension to compress. As it does so, the brake calipers can no longer squeeze the brake disc to stop the wheel. The brake disc is then forced to rotate, which makes it rock back and forth as the brake pads continue to press against it.

Uneven brake disc or rotor wear can lead to this phenomenon as well. If the rotor is warped from being overheated during heavy braking or it is out of round, then it will not be as smooth and effective a surface to press against your brake shoes.

A misaligned or unbalanced tire can also contribute to the braking instability. This will cause your vehicle to feel unstable when braking and should be addressed by a professional to ensure the safety of the driver and passengers. Loose or worn-out suspension components can also affect the stability of the vehicle when braking and should be inspected by a mechanic for damage or replacement if needed. This will improve your driving experience and help you get the most out of your car.
