A vibrating brake pedal is a sign that something is wrong, and it’s important to get the problem fixed quickly to keep you safe on the road. Experienced mechanics shared the main reasons for this phenomenon.
When the brake pedal begins to vibrate, this is a sure sign of a problem. One of the main reasons is a broken pad. This problem may not be immediately noticeable while driving, but it becomes apparent when braking hard. A broken pad can lead to vibrations in the steering rack and throughout the car body. When you press the brake pedal, a damaged pad may come into contact with the caliper pistons, which can lead to damage to the seals and rubber seals. This may compromise the integrity of the entire braking system.
When just one bolt on your car’s wheels is loose or missing, it creates dangerous play in the wheels, which can be a major catalyst for brake pedal vibration, especially during deceleration. Loose bolts aren’t just a problem during braking, as the shock and vibrations experienced while braking can make the problem worse, causing the bolt to become looser or even break.
A vibration in the brake pedal accompanied by a distinct noise when driving or decelerating may be a sign of a warped wheel bearing. You can carry out a simple play check by lifting the car with a jack. If there is any obvious wobbling or shaking when the wheel moves, this is a clear sign that the wheel bearing needs replacement.
