Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a socket set to loosen lug nuts while the car is still on the ground.
Raise the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Inspect and Clean Components

Remove the caliper bolts using a torque wrench.
Carefully lift the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Inspect the brake pads for uneven wear; replace if necessary.
Clean the caliper slides and brackets with brake cleaner and a wire brush to remove dirt and rust.

4. Lubricate Caliper Components

Apply high-temperature brake grease to the caliper slide pins and contact points to ensure smooth movement.
Reinstall the caliper over the rotor and secure it with the caliper bolts, tightening them to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the battery.
Pump the brake pedal several times to ensure proper brake engagement.
