The parking brake has a simple but essential job: to keep your vehicle stationary when needed. However, it’s common for these systems, whether manual or electronic, to run into issues. These problems can range from minor inconveniences to safety risks, so it’s essential to recognize them and know how to address them.
Here, we’ll walk through six of the most common parking brake issues, their symptoms, DIY fixes, and potential costs of repair.
Types of Parking Brake Systems
Before diving into the issues, let’s clarify the two main types of parking brake systems:
Manual Parking Brakes – Traditional systems operated by hand or foot. You may see a lever between the front seats, a pedal near the driver’s footwell, or occasionally a handle on the dashboard.
Electronic Parking Brakes (EPB) – Found in newer vehicles, these brakes engage at the push (or pull) of a button, with the braking force applied electronically.
For clarity, I’ll specify if each problem affects manual systems, electronic systems, or both.
Stuck or Frozen Parking Brake
A stuck or frozen brake can happen to both manual and electronic parking brakes, with different causes but similar symptoms. This problem is especially common in colder weather or when corrosion affects brake components.
Symptoms:
The parking brake won’t disengage
Grinding noise when trying to drive
Parking brake warning light remains on
How to Fix: For manual systems, try gently pulling up and releasing the lever a few times. This may help dislodge rust or debris. In electronic systems, check the manual for a release procedure—many have an emergency release function. Sometimes, simply turning the car off and back on can reset the system.
If cold weather is the issue, allow the engine to run for a while to generate heat, which can help release a frozen brake.
Cost: This may be free if you can resolve it yourself. However, if the issue persists, professional help may cost $100-$400 depending on your car type and the issue’s complexity.
Parking Brake Not Holding
If your car rolls forward or backward even when the parking brake is engaged, the brake is not holding as it should. This can happen with either manual or electronic systems and can be a risky issue if unnoticed.
Symptoms:
Car rolls when the brake is engaged
Need to engage gear or turn wheels to keep car stationary
Lever/pedal feels loose or lacks resistance
How to Fix: Start with a basic adjustment. For manual systems, you can usually tighten the brake cable by adjusting a nut on the brake mechanism (check your service manual for guidance). For electronic systems, recalibrating the system by holding the engage/disengage switch for about 30 seconds may work. Be sure to follow the procedure in your vehicle’s manual.
If adjusting doesn’t work, the problem could be due to worn brake pads/shoes, a stretched cable, or a faulty actuator in electronic systems. These repairs generally require a mechanic’s expertise.
Cost: Simple adjustments typically cost $50-$100. However, significant repairs can range from $200 to $500, depending on the problem’s severity.
Broken or Frayed Parking Brake Cable
Over time, parking brake cables can fray, stretch, or snap, similar to a worn-out rubber band. When this happens, the brake may not engage properly.
Symptoms:
Lever pulls up too easily
Car rolls even when the brake is engaged
Brake releases but won’t engage again
How to Fix: This is generally not a DIY fix unless you’re an experienced mechanic. Replacing the brake cable often requires working under the car and can involve accessing hard-to-reach areas.
Cost: Parts typically cost $50-$100, with labor adding another $100-$200. All in, expect to pay between $150 and $300 to replace a frayed or broken cable.
Electronic Parking Brake Malfunction
Electronic parking brakes have become common in newer cars. While convenient, they can malfunction due to sensor issues or errors in the control module.
Symptoms:
Parking brake warning light stays on
Brake won’t engage or disengage
Motor runs but no braking occurs
Error messages on infotainment system
How to Fix: First, consult your owner’s manual for reset procedures. Often, holding the button down for 30 seconds can reset the system. If not, a diagnostic tool may be needed to identify the problem accurately.
Cost: Simple resets can be free, but if a sensor or control module needs replacing, costs can vary. Sensor replacements are typically $100-$200, while control modules may cost $500-$1000.
Rust and Corrosion
It is a notorious culprit behind many brake issues, affecting both manual and electronic parking brakes. Rust and corrosion are more likely to occur in coastal areas or regions where road salt is common.
Symptoms:
Brake feels sticky or grinds when used
Brake gets stuck in engaged or disengaged position
Visible rust on exposed brake components
Grinding or scraping noises
How to Fix: If you notice rust early, moving the brake back and forth can sometimes break it up. For manual systems, applying a bit of penetrating oil to the cable can help (but avoid contact with the brake pads or shoes).
Cost: Minor rust removal with DIY supplies might cost around $20. However, if rust is severe and requires part replacement, repairs may run $200-$500, depending on the parts affected.
Warning Light Issues
Parking brake warning lights on the dashboard signal issues with the system’s functionality. Problems with warning lights can occur in both manual and electronic systems, and may indicate a minor or severe problem.
Symptoms:
Warning light stays on even when brake isn’t engaged
flashes Light intermittently
Light doesn’t illuminate when the parking brake is engaged
Light comes on while driving
How to Fix: For both systems, check to ensure the parking brake is fully disengaged. In manual systems, verify the lever or pedal is entirely released. In electronic systems, try engaging and disengaging the brake several times to reset the system.
If this doesn’t resolve the issue, inspect the brake cable for damage or slack in manual systems. In electronic systems, you can try resetting by disconnecting the battery briefly. For more complex issues, use a diagnostic scanner or visit a mechanic to identify and resolve error codes.
Cost: Costs vary greatly. For minor adjustments, it may be inexpensive, but for major repairs, refer to earlier sections for cost examples.
Final Thoughts
Maintaining your parking brake is essential for vehicle safety and stability. Whether you have a manual or electronic system, being aware of these common issues, their symptoms, and how to address them can save you time and money. Regular inspection and prompt attention to issues are the best ways to ensure your parking brake does its job effectively, keeping you and your car safe.
FAQs
Q: What is the purpose of the Park Brake Telltale light?
A: The Park Brake Telltale is an indicator on your dashboard designed to alert you when the parking brake is engaged or if there’s an issue with the brake system. It generally lights up red to capture attention, signaling the need for caution.
Q: Why is my Park Brake Telltale light on when the parking brake is not engaged?
A: If this light stays on even when the parking brake is off, it could signal a potential issue, such as low brake fluid, a problem with the hydraulic brake system, or a faulty sensor. Some vehicles may also turn on this light if there’s a detected malfunction in the braking system, like ABS issues or brake pad wear.
Q: Is it safe to drive with the Park Brake Telltale light on?
A: Generally, driving with this light on is not recommended unless you’re sure it’s due to an engaged parking brake. If the telltale light stays on due to a fault, it could mean your brakes are compromised, which could be dangerous. It’s best to have the brake system inspected by a professional if the light persists.
Q: What should I do if the Park Brake Telltale starts flashing?
A: Flashing can indicate a serious issue that requires immediate attention, potentially a critical fault in the brake system. Pull over safely and check the brake fluid level. If that’s not the issue, consult a mechanic as soon as possible.
Q: Can a faulty Park Brake Telltale be recalled?
A: Yes, manufacturers may issue recalls if a defective telltale light affects safety. For instance, recent recalls on some heavy-duty trucks were issued due to a faulty park brake telltale light that could lead to brake failure.
