What Causes High-Speed Brake Vibration?
1 Answers
High-speed brake vibration occurs due to the following reasons: 1. After prolonged driving with multiple braking instances, the brake discs reach high temperatures. When emergency braking triggers the ABS system at this stage. 2. ABS (Anti-lock Braking System) operates as electronically controlled pulse braking, where the brake caliper alternately clamps and releases the brake disc. This intermittent forceful stretching generates heat during deceleration. 3. Excessive heat causes brake rotor deformation. The warped disc then exhibits wave-like distortion. During subsequent high-speed braking, when constrained by calipers, this uneven disc surface vibrates. These vibrations transmit through steering linkages and suspension to the vehicle body and steering wheel, causing body tremors and directional instability.
