Lift the rear of the vehicle using a jack and secure it with jack stands.
Locate the parking brake cable connection at the rear brakes.
Inspect the cable for any signs of wear or damage. If damaged, replace the cable.
If the cable is intact, adjust the cable tension using the adjustment nut located near the lever or at the rear brake assembly according to the manufacturer’s specifications.

4. Inspect Rear Brake Components
