A parking brake, or emergency brake, is a crucial safety feature that ensures your vehicle stays stationary when parked, especially on inclines. But what happens when it doesn’t work as expected? If you find that your parking brake won’t engage or disengage, it can be frustrating and concerning. Fortunately, diagnosing and fixing the problem can be easier than you think. Here’s a guide on how to troubleshoot common parking brake issues and prevent future failures.
1. Check for Cable Issues
The parking brake works by engaging a cable that connects the hand lever to the brake components at the wheels. The most common issue with a malfunctioning parking brake is a damaged or misaligned cable. If the cable is frayed, detached, or twisted, it will fail to engage properly. Inspect the entire length of the cable for any kinks, twists, or visible damage. If the cable appears to be in poor condition, it will likely need to be repaired or replaced.
Tip: Ensure the cable is securely attached to both rear brakes for the system to function properly.
2. Inspect the Brake Shoes or Pads
If the parking brake cable appears to be in good condition, the problem might lie with the brake shoes or pads. If they are improperly positioned or worn out, they won’t provide the necessary friction to engage the brake. For drum brakes, the brake shoes may need adjustment or even replacement. In the case of disc brakes, the calipers and pads should be checked for wear and alignment.
3. Examine the Parking Brake Lever or Mechanism
Over time, the parking brake lever or the mechanism that controls it may wear out or become loose, preventing the brake from engaging. If you feel that the lever is not working as it should, it may require lubrication or tightening. Additionally, check the bell crank (the lever in front of the parking brake assembly) for any signs of rust or corrosion. This component can freeze up, particularly in cold or wet weather, causing the brake to become stuck.
4. Address Rust and Corrosion Issues
If your vehicle has been exposed to wet or salty environments, rust and corrosion may build up on the components of the parking brake system. In this case, the parts may seize, causing difficulty in engaging or disengaging the brake. Clean and lubricate any parts showing signs of rust, and consider replacing severely corroded components.
5. Consider Weather-Related Freezing
In cold climates, it’s not uncommon for the parking brake to freeze. When wet weather conditions mix with low temperatures, moisture in the brake components can cause them to freeze. To resolve this issue, start the car and let it warm up. This may take some time, but it should help thaw out any frozen components.
How to Prevent Parking Brake Issues
- Use Your Parking Brake Regularly
Frequent use of the parking brake can prevent rust, corrosion, and other issues. It also ensures that the brake remains functional when you need it. - Warm Up the Vehicle in Cold Weather
If you live in an area with cold or wet conditions, letting your car warm up before using the parking brake can help prevent freezing. - Avoid Over-tightening
Using excessive force to engage the parking brake can cause wear on the cable and other components. Gently engage and release the brake to ensure it operates smoothly. - Routine Maintenance
Regularly inspect and lubricate the parking brake system to keep it in good working order. This will help prevent future issues and extend the lifespan of the components.
FAQs About Parking Brake Issues
