What Causes Abnormal Brake Pedal Feel?
1 Answers
Abnormal brake pedal feel is typically caused by foreign objects entering between the brake pads and brake discs. Below are detailed explanations: 1. Vacuum Level Issues: Factors affecting vacuum level include: cracks in the atmospheric valve seat, fatigue damage to the diaphragm, cracks or failure of the vacuum valve seat, and failure of the vacuum hose check valve. 2. Free Travel Issues: Insufficient or nonexistent pedal free travel may lead to stiff braking or excessive pedal force. 3. Jump Value and Jump Point Issues: The jump value is not only the main cause of stiff braking but also serves as a quantitative indicator. A high jump value is determined by the position of the jump point, which also affects the initial pedal force perception.
