If you hear a high squealing sound coming from your car when you brake it is probably time to replace your brake pads or you might need to reline/replace your brake shoes.
All brakes work by introducing friction to the forward motion of your car’s wheels. The friction makes it harder and harder for the wheels to go forward, which means they stop. In physics terms, this means your brake pads are turning the car’s kinetic energy into heat energy. Disc brakes do this by means of a friction pad (the brake shoe or brake line) that presses into contact with a rotor (the disc).
After a while, all that friction causes erosion. Brake relining just means replacing the friction pads.
If there’s less than 1/4 inch of friction material, it’s about time to replace the brake shoes. If there’s less than 1/8 inch, you have no time to waste, the lack of friction material could be dangerous. It could be causing damage to the brake rotors (discs), which can be costlier to replace.
If there is some damage to the brake rotors you will have to get it skimmed to smooth out any deep gouges in the discs. That process basically involves sanding away the scars to create a new, smooth surface. If you’ve already done this, the discs might be too thin to keep using. That probably means it’s time to replace them.
Brake calipers squeeze the brake pads against the surface of the brake rotor creating friction to slow or stop the vehicle. They’re a hydraulic system, so they can develop leaks and corrosion under normal use.

Check brake pad thickness and replace if necessary in case of:
- Loud noise when applying brake pressure
- Serious damage to brake disc surface, caused by the steel back plate contacting the cast iron brake disc
- Vehicle pulling to one side due to unbalanced brake effect on both sides of an axle
