Brake pads are components of disc braking systems. The pad is made of a friction material mounted inside the caliper, where it can press against the rotor surface, slowing the rotation.
Brake pads are a wear item on a car, as they subtly degrade with use. This degradation is a normal function of braking. You must inspect your pads regularly to ensure safety. If a pad is allowed to wear too far, the caliper will contact the disc directly, potentially scoring the disc and damaging the caliper.
Pads come in multiple materials for varied use cases. Unless you’re taking your vehicle to the track or towing heavy loads, follow the vehicle manufacturer’s guidance on which pads to employ.
Brake pads can last for years and tens of thousands of miles, or they can fail in months and under 5,000 miles, depending on how and where you drive and the pad’s design. Hard braking wears pads quickly. Dirt and contamination from off-roading or driving in sandy conditions can accelerate decay.
Brake pads cost $30 to hundreds, depending on make, model, and composition. A home mechanic with moderate skill and the right tools can change a set of brake pads in an afternoon, saving substantial shop fees.
