Yes, a defective brake booster can cause pedal vibration. When the brake booster fails to provide the necessary assistance, it can lead to uneven pressure in the brake system, resulting in vibrations in the brake pedal during use. Additionally, issues such as air leaks or internal failures can contribute to this problem, affecting overall braking performance and feel. If you experience pedal vibration, it's advisable to have the brake system inspected by a professional.
Accumulation of brake dust over time will cause the calipers to stick and the brakes will heat up from the friction. They might need cleaning and relubing. Driving with your foot resting on the brake pedal will also do it.
