Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Use a socket set to remove the caliper bolts and take off the caliper.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring proper orientation.
5. Reinstall the caliper and torque the caliper bolts to manufacturer specifications (usually around 20-25 lb-ft).

3. Replace Brake Rotors (if necessary)

Sub-steps:
1. After removing the caliper, take off the rotor by removing any retaining screws or clips.
2. Clean the hub surface with a wire brush.
3. Install the new rotor, ensuring it fits flush against the hub.
4. Reinstall the caliper over the new pads and rotor.

4. Check and Replace Brake Fluid

Sub-steps:
1. Remove the cap from the master cylinder reservoir.
2. Check the fluid condition; if it's dark or contaminated, it needs replacing.
3. Use a brake bleeder kit to remove old fluid from the system.
4. Refill with new brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).

5. Inspect and Replace Brake Lines (if leaking)

Sub-steps:
1. Locate the affected brake line using visual inspection.
2. Use a wrench to disconnect the damaged line from the caliper and master cylinder.
3. Install a new brake line, ensuring all connections are tight.
4. Bleed the brake system to remove any air.
