Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Remove Rear Wheel

Use a jack to lift the rear of the vehicle and secure it on jack stands.
Use a lug wrench to remove the rear wheel bolts and take off the wheel.

3. Inspect and Clean Brake Components

Remove the brake caliper by unbolting it from the mounting bracket (typically 2 bolts).
Carefully slide the caliper off the rotor without damaging the brake line.
Inspect the brake pads for uneven wear or damage; replace if necessary.
Check the rotor for scoring or warping; machine or replace if needed.
Clean the caliper slide pins and lubricate them with high-temperature brake grease.

4. Test and Replace Caliper if Necessary

Move the caliper piston back using a brake caliper tool if the piston is stuck.
If the caliper is not functioning properly, replace it with a new or remanufactured caliper.
Reinstall the caliper over the rotor and secure it with the mounting bolts to the specified torque.

5. Reassemble and Reinstall Wheel

Reinstall the wheel and hand-tighten the lug bolts.
Lower the vehicle from the jack stands and fully tighten the lug nuts to the manufacturer’s torque specification.

6. Reconnect Battery and Test

Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pressure is restored.
Test drive the vehicle at low speeds to check for brake function and listen for any unusual noises.
