Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Use a caliper tool to compress the brake caliper piston.
3. Remove the caliper mounting bolts and take off the caliper.
4. Remove the old brake pads from the caliper bracket.
5. Install new brake pads in the caliper bracket.
6. Reinstall the caliper over the new pads and tighten the mounting bolts to the manufacturer’s specifications (usually around 20-30 ft-lbs).

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are worn or damaged, remove them by taking off the caliper bracket.
2. Clean the hub surface before installing new rotors.
3. Install new rotors and ensure they are seated correctly.
4. Torque the rotor retaining screws (if applicable) to the manufacturer's specifications.

4. Bleed Brake System (if air is present)

Sub-steps:
1. Connect a brake bleeder kit to the brake caliper.
2. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
3. Close the bleeder valve before the pedal is fully released.
4. Repeat until fluid runs clear and free of air bubbles.

5. Final Inspection and Reassembly

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually around 100 ft-lbs).
3. Check the brake fluid level in the master cylinder and add fluid as needed.
