You may also feel the seat vibrating, the steering wheel shaking, or the vehicle noticeably pulling forward and backward when you press the brake pedal.
Brake shudder is a vibration that is felt through the steering wheel, brake pedal, and suspension when the brakes are applied at high speeds. You need a dial indicator to check.
