Why is there severe jerking when braking slowly to a complete stop?
2 Answers
Severe jerking when braking slowly to a complete stop is mainly caused by excessively worn brake pads that need replacement. Here is an introduction to automotive brake pads: 1. Introduction: Automotive brake pads, also known as brake linings, refer to the friction materials fixed on the brake drums or discs that rotate with the wheels. The friction linings and blocks bear external pressure to generate friction, thereby achieving vehicle deceleration. 2. Maintenance methods: (1) Apply strong pressure when braking. (2) Replace the air filter element with a sponge of the same size. (3) Attach a layer of black felt or flannel to the inner side of the front wheel protective panel to reduce tire noise. (4) Use pliers to adjust the gap at the connection of the wiper blade and the rubber blade holder to eliminate wiper blade vibration and noise.
I've been driving for over 20 years and have experienced that sudden jerking sensation when coming to a complete stop several times. It feels like the car gets stuck and then bounces back, which is quite uncomfortable. This is usually caused by uneven or warped brake rotor surfaces. When you brake at low speeds for extended periods, the friction heat becomes uneven, leading to unstable brake pad engagement. Sometimes, rust buildup on the rotors from rainy weather or prolonged lack of car washing can also contribute to this issue. Additionally, the ABS (anti-lock braking system) might engage at low speeds, especially on slippery surfaces, where it rapidly releases the brakes to maintain control, resulting in that jerking sensation. For safety reasons, I recommend getting your brake rotors and pads professionally inspected as soon as possible—don't ignore it. Delaying could increase the risk of longer braking distances. Also, regularly using brake cleaning agents for maintenance can help prolong the lifespan of these components.
