Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the negative battery terminal to avoid electrical issues.

2. Wheel Removal

Use a lug wrench to loosen wheel lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the rear wheels.

3. Brake Caliper Removal

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and support it with a bungee cord or wire (do not let it hang by the brake line).
Inspect the caliper for any signs of sticking or damage.

4. Brake Pad and Rotor Inspection

Remove the brake pads from the caliper bracket and inspect for even wear.
Check the rotor for scoring, warping, or excessive wear.
If pads or rotors are worn beyond specifications, replace them.

5. Caliper Service

Clean the caliper slides and lubricate them with high-temperature brake grease.
If the caliper piston is stuck, use a brake caliper tool to retract it and ensure it moves freely.
If necessary, replace the caliper with a new one.

6. Reassembly

Reinstall the brake pads into the caliper bracket.
Position the caliper back onto the rotor and secure it with caliper mounting bolts.
Reinstall the rear wheels and hand-tighten the lug nuts.

7. Brake Fluid Check

Inspect the brake fluid reservoir and fill with the recommended brake fluid type if low.
Bleed the brake lines if air has been introduced into the system.

8. Final Checks

Reconnect the negative battery terminal.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
