Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks around the front wheels for added safety.
Disconnect the negative battery terminal to prevent electrical issues.

2. Raise the Vehicle

Use a jack to raise the rear of the vehicle.
Secure the vehicle with jack stands.
Remove the rear wheels using a socket wrench.

3. Remove Brake Components

Remove the brake caliper by unscrewing the caliper bolts (use a torque wrench to ensure proper reassembly).
Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid stress on the brake line.
Remove the brake pads from the caliper bracket.

4. Inspect and Clean

Inspect the brake rotor for grooves or scoring. If damaged, replace it.
Clean the caliper bracket and guide pins with brake cleaner to remove dust and debris.
Apply brake grease to the caliper slide pins to ensure smooth movement.

5. Check and Replace Components

If the brake pads are worn unevenly or contaminated, replace them with new ones.
Inspect the caliper for binding. If the caliper is sticking, consider replacing it.
Ensure the parking brake cable is not too tight and is functioning correctly.

6. Reassemble

Reinstall the brake pads into the caliper bracket.
Reattach the caliper and tighten the bolts to the manufacturer’s specifications.
Reinstall the rear wheels and lower the vehicle back to the ground.

7. Final Inspection

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure proper brake function before driving.
