What Can Cause Brake Pad Wear On One Side and Not The Other?

A vehicle's braking system is a complex collection of parts, including brake pads. Brake pads are essential to stopping your car as they are the part connected to the wheels. After some inspection, you may notice uneven wear and tear on your brake pads. It is natural for front and back brake pads to have uneven damage since the front ones are responsible for braking. The following are possible causes of uneven brake pad wear:

Caliper Failure

Caliper failure is the most common cause of uneven brake pad wear and tear. The calipers have a piston that puts pressure on the brake pads to stop the car. When you release the brake pad, a seal in the caliper retracts the piston away from the brake pad.
The seal is made of rubber and loses its ability to pull the piston back with time. The calipers can also get stuck, causing one brake rotor to exact more pressure on a brake pad than the others.

Brake Rotor Damage

Brake rotors can deteriorate unevenly, leading to Disc Thickness Variation (DTV). Sticking calipers, hard braking, rust, and dirt in the rotors all contribute to DTV.
When a rotor has DTV, it will cause uneven wear on the brake pads.

Brake Hose Issues

Brake hose failure happens when the metal brake line is damaged due to massive braking forces. The rubber brake hose can also collapse because it is old.
Brake hose failure will create enough pressure in the hydraulic system to force the piston caliper outward. It will then drag the brake pad along the rotor, causing it to experience more erosion than the others.
