Possible Causes of Brake Judder
Brake judder can be a terrifying experience that hampers the safety and performance of any vehicle. Picture yourself driving down a steep hill, and as you step on the brakes, the steering wheel begins to shake uncontrollably, making it challenging to keep your vehicle in the intended path. Brake judder can happen to any driver and is characterized by a vibration that occurs through the steering wheel and brake pedal. It can be caused by several factors, including worn-out brake pads and rotors, unbalanced tires, warped brake parts, and even unevenly tightened lug nuts. Discussed below are some of the possible causes of brake judder.
Worn-out brake pads and rotors is the most common cause of brake judder. Over time, brakes pads and rotors become thin, limiting their ability to create friction and slowing down the vehicle. As a result, the brake pads heat up and warp the rotors, resulting in a distinctive vibration that occurs when brakes are applied. This type of brake judder may also lead to squeaking brakes, and a burning smell when brakes are applied. Therefore, it is critical to inspect brake pads and rotors regularly to mitigate brake judder.
Unbalanced tires can also cause brake judder. Out-of-balance tires cause an awkward distribution of weight around the vehicle, making it challenging to control the vehicle through the brakes, leading to judder. To erradicate the possibility of brake judder caused by tire imbalance, it is of immense importance to get the tires balanced regularly. Finally, unevenly tightened lug nuts could also contribute to brake judder. Over-tightened or under-tightened lug nuts can cause unwanted stresses on the brake system, leading to brake judder. It’s essential to practice proper tightening techniques and torque specifications when loosening and tightening the lug nuts to prevent this issue. So far, we’ve discussed the different possible causes of brake judder, and the next step is to find solutions to this menace.
What is brake judder?
Brake judder is a term used to describe the vibration, pulsation, or shimmy felt through the steering wheel, brake pedal, or chassis while applying the brakes. It is a common problem that occurs in various types of vehicles, from daily drivers to high-performance sports cars.
