Imagine yourself cruising down the highway, enjoying the open road, when suddenly your car starts to shake violently every time you apply the brakes. This unsettling experience can be more than just a minor annoyance; it’s a serious safety concern that shouldn’t be ignored. Brake shaking, also known as brake pulsation, is a common problem that can stem from various issues with your braking system. Understanding the causes and potential solutions for this problem is crucial for ensuring your safety and the longevity of your vehicle.

Understanding Brake Shakes
Brake shaking, characterized by a vibrating sensation in the steering wheel and brake pedal when braking, is a clear indication that something is amiss within your braking system. This vibration can range from a slight tremor to a violent shaking, depending on the severity of the underlying issue. Ignoring brake shakes can lead to premature brake wear, reduced braking efficiency, and ultimately, a compromised ability to stop your vehicle safely.
Causes of Brake Shakes
Several factors can contribute to brake shakes, each requiring a specific diagnostic and repair approach. Some of the most common causes include:
- Warped Brake Rotors: Brake rotors, the discs that press against the brake pads to slow down the vehicle, can warp due to excessive heat, uneven wear, or manufacturing defects. Warped rotors create an uneven braking surface, causing the brake pads to vibrate against them, resulting in the shaking sensation.
- Damaged Brake Pads: Worn-out or damaged brake pads can also contribute to brake shakes. If the brake pads are unevenly worn, they may not make consistent contact with the rotors, leading to vibration.
- Loose Brake Components: Loose caliper bolts, brake lines, or other components in the braking system can cause the brakes to bind or vibrate, resulting in a shaking sensation.
- Wheel Balance Issues: While not directly related to the brakes, unbalanced wheels can also cause vibrations that are felt in the steering wheel, particularly when braking.
Diagnosing Brake Shakes
Identifying the root cause of brake shakes requires a thorough inspection by a qualified mechanic. They will typically use the following methods to diagnose the problem:
- Visual Inspection: The mechanic will visually inspect the brake rotors, pads, calipers, and other components for signs of wear, damage, or looseness.
- Brake Rotor Measurement: Using specialized tools, the mechanic will measure the thickness and runout (deviation from a perfectly flat surface) of the brake rotors to determine if they are warped.
- Brake Pad Inspection: The mechanic will check the thickness and condition of the brake pads, looking for uneven wear or damage.
- Wheel Balancing Test: If wheel balance is suspected, the mechanic will perform a wheel balancing test to identify any imbalances.
Repairing Brake Shakes
Once the cause of the brake shakes is determined, the mechanic will recommend the appropriate repair solution. Common repairs include: (See Also: Why Is the Brake System Light on? Common Causes Revealed)
- Brake Rotor Machining or Replacement: If the rotors are warped, they can be machined to remove the imperfections or replaced entirely.
- Brake Pad Replacement: Worn or damaged brake pads will need to be replaced.
- Caliper Repair or Replacement: If the caliper is damaged or malfunctioning, it may need to be repaired or replaced.
- Wheel Balancing: If wheel balance issues are identified, the wheels will be balanced to ensure even weight distribution.
- Tightening Loose Components: Any loose bolts or connections in the braking system will be tightened to ensure proper function.
Preventing Future Brake Shakes
Regular maintenance is crucial for preventing future brake shakes. Here are some tips to help keep your brakes in top condition:
- Have Your Brakes Inspected Regularly: Get your brakes inspected by a qualified mechanic at least once a year or as recommended by your vehicle’s manufacturer.
- Replace Brake Pads and Rotors as Needed: Don’t wait until your brake pads are completely worn out to replace them. Follow the manufacturer’s recommended replacement intervals.
- Avoid Hard Braking: Hard braking can generate excessive heat, which can warp brake rotors. Try to brake smoothly and gradually.
- Drive Safely and Responsibly: Avoid aggressive driving habits, such as speeding and sudden lane changes, which can put extra stress on your brakes.
Car Brake Shakes When I Apply?
What to do if your car brake shakes?
If you experience brake shakes, it’s essential to address the issue promptly. Don’t delay seeking professional help. Driving with faulty brakes can be extremely dangerous. A qualified mechanic will be able to diagnose the problem accurately and recommend the necessary repairs.
When should you replace your brake pads and rotors?
Brake pad and rotor replacement intervals vary depending on driving habits, vehicle type, and environmental conditions. However, as a general guideline, brake pads should be inspected every 12,000 miles, and rotors should be inspected every 24,000 miles.
Can I drive with warped brake rotors?
While it’s possible to drive with warped brake rotors, it’s not recommended. Warped rotors can lead to reduced braking efficiency, uneven wear, and ultimately, brake failure. It’s best to have them machined or replaced as soon as possible. (See Also: Do I Need To Replace Rotors When Replacing Brake Pads? Find Out)
FAQs
What causes brake pulsation?
Brake pulsation, or brake shakes, is usually caused by warped brake rotors, worn brake pads, or loose brake components.
How much does it cost to fix brake shakes?
The cost of repairing brake shakes varies depending on the severity of the problem and the specific repairs required. It could range from a few hundred dollars for brake pad replacement to over a thousand dollars for rotor machining or replacement and caliper repair.
Can I fix brake shakes myself?
While some basic brake maintenance tasks can be performed by DIY enthusiasts, repairing brake shakes often requires specialized tools and knowledge. It’s generally recommended to have this work done by a qualified mechanic to ensure proper diagnosis and repair.
What are the dangers of driving with brake shakes?
Driving with brake shakes can be extremely dangerous. It can lead to reduced braking efficiency, making it harder to stop your vehicle safely. It can also cause the steering wheel to vibrate uncontrollably, making it difficult to maintain control of the vehicle. (See Also: What Is the Difference Between Brake Cleaner and Carburetor Cleaner?
