Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery cable to prevent electrical shorts.

2. Check Brake Fluid Level

Tools Required: None
Locate the master cylinder reservoir and check the brake fluid level.
If low, refill with the recommended brake fluid type (DOT 3 or DOT 4).
Reconnect the battery cable.

3. Inspect Parking Brake Cable

Tools Required: Socket set, pliers
Remove the rear wheels to access the parking brake assembly.
Visually inspect the parking brake cable for any signs of fraying or disconnection.
If damaged, replace the cable with a new one. Adjust the tension as per manufacturer specifications.

4. Test Parking Brake Switch

Tools Required: Multimeter
Locate the parking brake switch, typically found near the parking brake lever.
Disconnect the switch connector and test for continuity using a multimeter.
If there is no continuity when the brake is engaged, replace the switch.

5. Adjust Parking Brake

Tools Required: Socket set, torque wrench
If the parking brake lever feels loose, adjust the parking brake mechanism according to the manufacturer's specifications.
Ensure the lever has the correct travel distance (usually around 6-10 clicks) when engaged.
