What Causes Brake Pedal Vibration?
1 Answers
The cause of brake pedal vibration is uneven wear on the brake discs. This phenomenon mainly occurs when drivers frequently use intermittent braking (pumping the brakes) over extended periods, resulting in uneven brake disc surfaces with alternating high and low spots. When the brake pads grip these uneven surfaces during braking, it causes vibration. Therefore, drivers should use the braking system properly and standardizedly during driving to avoid subsequent problems. When the car engine is idling, activating the vehicle's electrical system is most likely to cause vibration. The engine's load increases when the electrical system is turned on, causing the idle speed to drop. To compensate for the vibration caused by the idle speed drop, the engine will automatically increase the RPM.
