Pulsing brakes are a direct result of the rapid shifting of the brake assembly against the braking surface. The rotor or drum brake surface must be flat to enable smooth braking. Braking surfaces that have significant variation due to warping, damage, uneven wear or misalignment cause the brakes to unevenly be applied. As the brake pads contact the high spots, the brakes grab slightly. When the brake pads leave the high spots, the braking strength is reduced. As the wheel turns rapidly, the brake pads have uneven pressure between the high and low spots, causing pulsation.
