Why is there severe jerking when braking slowly to a complete stop?

[DiJoanna]

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.

As a car enthusiast, I pay special attention to these small details. Severe jerking when braking slowly to a stop is mostly caused by uncoordinated brake caliper movement, possibly due to aging hydraulic fluid causing unstable pressure; it could also be that the suspension system's shock absorbers have deteriorated, exacerbating the vehicle's shaking during deceleration. Recalling when I repaired my own car, I found that regularly changing the brake fluid can prevent this issue, as new fluid has better lubrication properties, avoiding stickiness. If you're good at DIY, check if the tire pressure is balanced—uneven pressure can amplify the bumps. Remember, this jerking isn't just annoying; it also indicates component fatigue. Early maintenance can save you from bigger repairs later.

Common brake jerking issues are particularly noticeable when coming to a stop at low speeds. This is likely the ABS system engaging to prevent wheel lock-up, or it could be due to poor coordination during automatic transmission downshifts, where engine speed changes affect stability. A quick check for brake pad wear or fluid leaks in the pump can help identify the cause. It's recommended to drive to a professional workshop for diagnosis—safety first.
