Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and securely on jack stands.
Disconnect the negative battery cable to prevent any electrical issues.

2. Inspect and Adjust the Parking Brake Cable

Locate the parking brake cable under the vehicle.
Check for any signs of fraying or damage. If damaged, replace the cable.
Adjust the cable tension by locating the adjustment nut and turning it to increase or decrease tension until the cable has proper slack.

Remove the rear wheel using a socket set.
Remove the brake drum if equipped, or remove the rear disc brake caliper if applicable.
Inspect the parking brake shoes or pads for wear; replace if they show significant wear or damage.
Clean the backing plate and any rust or debris with brake cleaner.

4. Reassemble and Test

Reinstall the parking brake shoes or pads, ensuring all components are correctly seated.
Reattach the brake drum or caliper and tighten bolts to manufacturer specifications (usually between 15-25 ft-lbs).
Reinstall the wheel and lower the vehicle.
Reconnect the negative battery cable.
