Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, brake caliper tool, and safety goggles.
Ensure the vehicle is on a flat surface, and engage the parking brake.
Loosen lug nuts on the wheel before lifting the vehicle.

2. Remove Wheel

Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake caliper.

3. Inspect Caliper

Visually inspect the caliper for any signs of leaks or damage.
Check the brake pads for uneven wear; replace if necessary.
Use the brake caliper tool to check the caliper piston movement.

4. Repair or Replace Caliper

If caliper is leaking:
- Remove the caliper by unscrewing the caliper mounting bolts.
- Disconnect the brake line from the caliper (ensure to catch any leaking fluid).
- Install a new caliper, ensuring to use fresh brake fluid and bleed the brakes afterward.
If caliper is sticking:
- Clean the caliper slides and lubricate them with high-temperature brake grease.
- Ensure the rubber boots are intact and replace if necessary.

5. Reassembly

Reattach the brake line to the new or repaired caliper.
Secure the caliper with mounting bolts to the manufacturer’s torque specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and tighten the lug nuts to the specified torque.

6. Test the Brakes

Lower the vehicle and pump the brake pedal to ensure proper caliper function.
Check for leaks around the caliper after bleeding the brakes.
