Car Jerks When Braking Transmission: Causes and Solutions
When driving a car, smooth and controlled braking is crucial for both safety and comfort. However, if your car jerks when braking, it can be quite alarming and frustrating. This issue can occur due to various reasons, including problems with the transmission. In this article, we will explore the causes behind a car jerking when braking and provide some possible solutions to resolve this issue.
Causes of Car Jerking When Braking
1. Transmission Issues: One of the primary causes of a car jerking when braking is problems with the transmission. If the transmission is not functioning properly, it can lead to a rough and uneven braking experience. Common transmission-related problems include low transmission fluid, worn-out gears, or a faulty torque converter.
2. Brake Caliper Issues: Another possible cause is a malfunctioning brake caliper. The brake calipers are responsible for applying pressure to the brake pads, which in turn press against the rotors to slow down the vehicle. If a caliper gets stuck or fails to function correctly, it can result in uneven braking, causing the car to jerk.
3. Brake Pad Problems: Worn-out or damaged brake pads can also contribute to a jerking sensation when braking. When brake pads become thin or worn, they may not apply even pressure on the rotors, leading to an uneven braking experience. This uneven pressure can cause the car to jerk.
4. Rotor Issues: If the brake rotors become warped or damaged, it can lead to a jerking sensation when braking. Warped rotors can cause the brake pads to apply uneven pressure, resulting in a shaky or jerky motion. Over time, excessive heat or wear can cause the rotors to become warped, affecting the braking performance.
Solutions for Car Jerking When Braking
1. Transmission Fluid Check and Refill: If the jerking is caused by low transmission fluid, check the fluid levels and top it up if necessary. However, if the fluid is significantly low, it may indicate a leak or other underlying issues, requiring a professional inspection and repair.
2. Transmission Repair or Replacement: If the jerking persists even after checking the fluid levels, it might be necessary to get the transmission checked by a qualified mechanic. Depending on the severity of the issue, repairs or even a complete transmission replacement may be required.
3. Brake Caliper Inspection and Repair: If a stuck or malfunctioning brake caliper is the cause of the jerking, it will need to be inspected and repaired by a professional. They will check if the caliper needs to be replaced or if it can be repaired by cleaning or lubricating the parts.
4. Brake Pad and Rotor Replacement: If the jerking issue is due to worn-out brake pads or damaged rotors, replacing them is the solution. Brake pads should be replaced regularly according to the manufacturer’s recommendations, and the rotors should be resurfaced or replaced when necessary.
Q: Can I continue driving if my car jerks when braking?
A: It is not advisable to continue driving if your car jerks when braking, as it may indicate a serious issue with the braking system or transmission. It’s best to have it inspected and repaired by a professional mechanic to ensure your safety on the road.
Q: How much does it cost to repair a transmission?
A: The cost of transmission repair can vary depending on the extent of the damage and the specific make and model of your car. On average, it can range from a few hundred dollars for minor repairs to several thousand dollars for a complete transmission replacement.
Q: How often should I replace my brake pads?
A: Brake pads typically need to be replaced every 30,000 to 70,000 miles, depending on driving habits and the type of brake pads used. It is crucial to follow the manufacturer’s recommendations and have regular inspections to ensure the safety and performance of your braking system.
In conclusion, a car jerking when braking can be a sign of various issues, including problems with the transmission, brake calipers, brake pads, or rotors. It is essential to address this issue promptly to ensure your safety and the longevity of your vehicle. Regular maintenance and inspections, along with timely repairs, can help prevent car jerking and provide a smoother and safer driving experience.
