Brake pad
Presses friction material against the disc to slow the car.
Inside the brake caliper on both sides of the disc.
A backing plate supports a friction compound chosen for its temperature, noise and wear behavior.
The gripping blocks in a powerful bicycle brake.
Wear warnings, grinding or reduced braking require inspection of the complete brake assembly.
Pads and discs are measured wear items. Driving, environment and regenerative braking change wear; use the actual inspection limits.
Ordinary friction service differs greatly from carbon-ceramic replacement or hydraulic-controller work; obtain a vehicle-specific quote.
BMW M and standard pads may have different compounds and fitment despite a similar outline.
BMW models with hydraulic friction brakes; performance equipment and parking-brake design vary.
