Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel Assembly

Tools Required: Jack, jack stands, lug wrench
Loosen lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel by fully unscrewing the lug nuts.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench
Locate the caliper mounting bolts and remove them using a socket.
Carefully slide the caliper off the brake rotor. Support the caliper with a bungee cord or rope to avoid straining the brake line.

4. Inspect and Clean Caliper Components

Check the caliper piston and bore for dirt or corrosion.
Sub-steps:
- Clean the caliper with brake cleaner.
- Inspect the piston for proper movement.
- If the piston is stuck, consider using a caliper tool to compress it slightly and free it.

5. Lubricate Slide Pins

Remove the slide pins from the caliper bracket.
Clean the pins thoroughly and apply high-temperature brake grease.
Reinstall the slide pins, ensuring they move freely.

6. Reassemble and Install

Reattach the caliper to the bracket, ensuring it is aligned correctly.
Reinstall the caliper mounting bolts and torque them to the manufacturer's specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the manufacturer’s specifications (often 80-100 ft-lbs).
Pump the brake pedal several times to ensure proper caliper function before driving.
