The parking brake, often referred to as the handbrake, is a crucial safety feature in any vehicle. It prevents the car from rolling unintentionally when parked, ensuring your safety and the safety of others. Over time, the parking brake system can wear down, requiring repairs or adjustments. One common issue that arises is a stuck or malfunctioning parking brake cable, which connects the handbrake lever to the brake calipers. Removing the parking brake cable from the backing plate is a necessary step in troubleshooting and repairing this issue. While it may seem daunting, this process can be accomplished with the right tools and knowledge. This comprehensive guide will walk you through the steps involved in safely and effectively removing the parking brake cable from the backing plate.
Understanding the Parking Brake System
Before diving into the removal process, it’s essential to understand the basic workings of the parking brake system. The system typically consists of the following components:
Handbrake Lever
This lever, located inside the vehicle, is what you pull to engage the parking brake. It transmits force to the parking brake cable.
Parking Brake Cable
This cable runs from the handbrake lever to the backing plate of the rear wheels. It transfers the force applied to the lever to the brake mechanism.
Backing Plate
This metal plate is attached to the rear wheel hub and houses the parking brake components, including the brake shoes or pads.
Brake Shoes or Pads
These friction materials are pressed against the brake drum or rotor when the parking brake is engaged, creating the braking force.
Adjuster Mechanism
This mechanism allows you to adjust the tension of the parking brake cable, ensuring proper engagement and disengagement.

Step-by-Step Removal Process
Now, let’s proceed with the step-by-step removal of the parking brake cable from the backing plate:
1. Access the Backing Plate
Locate the rear wheel where the parking brake cable is connected. You may need to remove the wheel and any protective covers to access the backing plate.
2. Identify the Cable Attachment Point
Examine the backing plate and locate the point where the parking brake cable is attached. This is usually a bracket or a clevis pin.
3. Loosen the Cable Clamp
Using a socket wrench, loosen the nut or bolt that secures the cable clamp to the backing plate. Be careful not to overtighten or damage the threads.
4. Disconnect the Cable from the Backing Plate
Once the clamp is loosened, carefully remove the cable from the backing plate. If it’s a clevis pin, you may need to use a flathead screwdriver or pliers to pry it out.
5. Remove the Cable from the Adjuster Mechanism
If the cable is connected to an adjuster mechanism, you’ll need to disconnect it as well. This usually involves releasing a spring clip or removing a bolt.
6. Inspect the Cable and Backing Plate
Take this opportunity to inspect the parking brake cable for any signs of wear, fraying, or damage. Also, check the backing plate for rust, corrosion, or other issues.

3. Tighten the Cable Clamp
Using a socket wrench, tighten the nut or bolt that secures the cable clamp to the backing plate. Make sure it’s snug but avoid overtightening.
4. Test the Parking Brake
Engage and disengage the parking brake several times to ensure it operates smoothly and effectively. Adjust the cable tension if necessary.
