Car Jerks When Braking

Braking is a fundamental aspect of operating a vehicle, ensuring our safety on the road by allowing us to slow down or stop entirely. While braking should be a smooth and controlled experience, there are instances where your car may jerk during the process. This sensation can be disconcerting for many, and it’s essential to understand why it might be happening and how to address the issue. In this article, we’ll discuss the possible reasons behind a car jerking when braking and outline steps to help you resolve the problem.

Important Outline

1. Worn brake pads or shoes

One of the primary causes of jerking during braking is when the brake pads or shoes have worn down significantly, causing uneven friction upon application. As a general rule, it is recommended that you replace your brake pads every 50,000 miles, while brake shoes typically last about twice as long. To prevent jerking, be sure to have your brake pads and shoes checked regularly and replaced when necessary.

2. Warped brake rotors

Your brake rotors are responsible for dissipating the heat generated by the friction between the brake pad and rotor. Over time, this heat can cause the rotors to warp, leading to uneven contact between the pad and rotor and subsequently causing a jerking sensation during braking. Correcting this issue involves either having your rotors resurfaced or replacing them entirely.

3. Brake fluid contamination

Brake fluid plays a vital role in your braking system by transmitting the hydraulic pressure from your brake pedal to the brake pads. Contaminated brake fluid can result in poor pressure distribution, causing the car to jerk when braking. To resolve this, be sure to replace your brake fluid at least every two years or whenever it becomes contaminated.

4. Misaligned wheels or suspension

A misaligned suspension or wheel system can cause uneven weight distribution during braking, leading to a jerking motion. Have your car’s alignment and suspension checked and corrected by a professional to ensure a smooth and enjoyable driving experience.

5. A malfunctioning ABS system

The Anti-lock Braking System (ABS) is designed to prevent your wheels from locking up during hard braking. However, a malfunction within the ABS can cause the system to engage inappropriately, resulting in a jerking motion. Addressing this issue would require a mechanic to diagnose and repair the ABS components.

In conclusion, several factors may cause a car to jerk when braking, ranging from worn brake components to misaligned suspension or wheel systems. Identifying and addressing these issues can greatly improve your vehicle’s performance and your overall driving experience.

Step by Step Guide

To resolve the issue of a car jerking when braking, follow this step by step guide:

1. Inspect the brake pads and shoes: Determine whether they have worn down significantly, which can lead to uneven friction during braking. Regularly check and replace these components as needed.

2. Check for warped brake rotors: A rotor that has warped due to heat can cause a jerking motion when braking. Either resurface or replace the rotors to eliminate this issue.

3. Assess brake fluid quality: Contaminated brake fluid can result in poor pressure distribution during braking. Replace the brake fluid every two years or whenever it becomes compromised.

4. Check alignment and suspension: A misaligned suspension or wheel system can lead to uneven weight distribution when braking. Have a professional inspect and address these issues if needed.

5. Diagnose and repair ABS issues: In cases where the car’s ABS system is malfunctioning, consult a mechanic to identify and fix the problem.

1. How often should brake pads be replaced?

As a general rule, brake pads should be replaced every 50,000 miles. However, this may vary depending on the specific make and model of the vehicle, as well as driving habits.

2. Can warped brake rotors be repaired?

Warped brake rotors can often be resurfaced by a professional mechanic. In some cases, the rotors may need to be replaced entirely.

3. How can I tell if my brake fluid is contaminated?

Contaminated brake fluid typically appears darker than fresh brake fluid, which is usually clear or slightly amber. A spongy or soft brake pedal may also be an indication of contaminated brake fluid.

4. What are the symptoms of a misaligned suspension or wheel system?

Common signs of a misaligned suspension or wheel system include uneven tire wear, pulling to one side while driving, or an off-center steering wheel.

5. How can I determine if my ABS system is contributing to the car jerking when braking?

Consult a trusted mechanic to diagnose and repair any ABS-related issues. They can use specialized diagnostic tools to determine if the ABS system is contributing to the problem.


Car jerking when braking can be an unsettling experience for drivers. Understanding the potential causes and following the outlined steps can help identify and resolve the issue, ensuring a smooth and safe driving experience. Remember to stay attentive to your vehicle’s performance and perform regular maintenance to prevent future problems. Consult a mechanic if you’re ever unsure about how to address a specific issue with your car’s braking system.
