Let’s take a closer look at the how, what, and why of replacing brake pads and/or shoes on your vehicle.

WHAT ARE BRAKE PADS? WHAT ARE BRAKE SHOES?

Auto manufacturers install two types of brakes on passenger vehicles: disc brakes and drum brakes.

Both use friction to slow your vehicle, but there are differences too.

Disc brakes use “pads” of specially engineered pieces of friction material made of organic, metallic or ceramic substances pressed against a rotor or “disc” when the driver steps on the brakes.

The resulting friction slows the vehicle. Disc brakes are found on the front axles of all modern passenger vehicles and on the rear axle of many, too.

Drum brakes also use friction material, much like disc brake pads
