Warped brake rotors: Brake rotors are the discs that the brake pads press against to slow down or stop the car. If the rotors are warped, they can cause the brake pads to vibrate, which in turn causes the car to tremble. Warped rotors can be caused by overheating, uneven wear, or damage from road debris.
Uneven brake pad wear: Uneven brake pad wear can also cause the car to tremble when braking. This can be caused by a variety of factors, such as a stuck brake caliper, a faulty brake hose, or a problem with the brake master cylinder.
Faulty wheel bearings: Wheel bearings are responsible for allowing the wheels to rotate smoothly. If a wheel bearing is faulty, it can cause the wheel to wobble, which can in turn cause the car to tremble when braking.
Driveline issues: Driveline issues, such as a worn universal joint or a faulty driveshaft, can also cause the car to tremble when braking.
Loose lug nuts: Loose lug nuts can allow the wheel to move slightly, which can cause the car to tremble when braking.
If you are experiencing a trembling sensation when braking, it is important to have the car inspected by a qualified mechanic as soon as possible. Ignoring this issue can lead to more serious problems, such as brake failure.
