Why does brakes pulsate when applied?

Brake pulsation typically occurs due to uneven wear or warping of the brake rotors, which can create inconsistent contact between the brake pads and rotors. This can lead to vibrations felt in the brake pedal when pressure is applied. Other causes may include issues with the brake calipers or the presence of contaminants on the braking surface. Regular maintenance and timely replacement of worn components can help prevent this issue.
