Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, socket set, c-clamp or brake caliper tool, torque wrench.
Raise the vehicle using a jack and secure with jack stands.
Remove the wheel using a lug wrench.

2. Remove the Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using the socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid straining the brake line.

3. Inspect and Clean

Sub-steps:
1. Inspect the caliper, caliper bracket, and rotor for signs of wear or damage.
2. Clean the caliper and bracket using brake cleaner to remove dust and debris.
3. Check the caliper piston for corrosion; if present, it may need to be replaced.

4. Lubricate Components

Sub-steps:
1. Apply brake grease to the caliper slides and mounting points to ensure smooth operation.
2. If replacing the caliper, prepare the new caliper by applying grease to the piston and seals.

5. Reinstall the Caliper

Sub-steps:
1. Position the caliper back onto the rotor and align with the mounting holes.
2. Insert and tighten the caliper mounting bolts to the manufacturer's specified torque.
3. Reinstall the wheel and tighten the lug nuts in a crisscross pattern.

6. Final Checks

Sub-steps:
1. Lower the vehicle back to the ground.
2. Pump the brake pedal several times to ensure the caliper piston is seated correctly.
3. Check the brake fluid level and top off if necessary.
