Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts using a socket set while the vehicle is still on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Remove Brake Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using the appropriate socket.
2. Carefully slide the caliper off the brake rotor.
3. Hang the caliper using a bungee cord or similar device to avoid straining the brake line.

4. Inspect and Clean

Sub-steps:
1. Inspect the caliper for damage or corrosion.
2. Clean the caliper bracket and the slides with brake cleaner and a wire brush.
3. Lubricate the caliper slides with high-temperature brake grease.

5. Replace or Repair Components

Sub-steps:
1. If the caliper is damaged, replace it with a new caliper.
2. Replace any worn or damaged brake pads.
3. Inspect and replace the rubber boots on caliper slides if necessary.

6. Reinstall Caliper and Wheel

Sub-steps:
1. Slide the caliper back onto the rotor and align it with the mounting holes.
2. Reinstall the caliper mounting bolts and torque them to the manufacturer’s specifications (generally around 20-25 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.

7. Test Brakes

Sub-steps:
1. Reconnect the battery.
2. Pump the brake pedal to ensure proper caliper engagement.
3. Test the vehicle at low speeds in a safe area to ensure brakes function correctly without sticking.
