Solution

1. Preparation

Gather all required tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Raise Vehicle and Remove Wheel

Use a jack to lift the vehicle and support it with jack stands.
Use a lug wrench to remove the wheel, exposing the brake assembly.

3. Inspect and Remove Caliper

Inspect the caliper for signs of corrosion or damage.
Remove the caliper mounting bolts using a socket wrench.
Carefully slide the caliper off the brake rotor, supporting it to avoid straining the brake line.

4. Clean and Lubricate

Clean the caliper slides and mounting brackets using brake cleaner and a wire brush to remove dirt and debris.
Apply high-temperature brake grease to the caliper slides and mounting points to ensure smooth movement.

5. Check and Replace Components

Inspect the brake pads for wear; replace them if they are unevenly worn.
If the caliper piston is stuck, use a caliper tool to compress and then release the piston. If it does not move freely, replace the caliper.
Inspect and replace slider pins if they are worn or damaged.

6. Reassemble and Reinstall

Reinstall the caliper, ensuring it is correctly aligned with the rotor.
Tighten the caliper mounting bolts to the manufacturer's specified torque (typically around 25-35 Nm, but consult the service manual for exact specifications).
Reinstall the wheel and lower the vehicle.
