What Causes Brake Pedal Vibration When Braking at High Speeds?
1 Answers
Reasons for brake pedal vibration during high-speed braking: 1. Uneven brake disc surface with excessive radial runout: This causes inconsistent contact between brake pads and discs during braking, resulting in fluctuating braking force and vehicle vibration, particularly noticeable during light braking. 2. Significant wheel alignment deviation: Especially incorrect front wheel alignment angles or excessive toe-in. This makes the vehicle difficult to control during acceleration, with subtle but uncomfortable vibration. 3. Improper tire pressure: Excessive pressure causes stronger vibration at higher speeds, while insufficient pressure leads to vehicle pulling.
