Solution

1. Preparation

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

2. Check and Replenish Brake Fluid

Sub-steps:
- Open the hood and locate the brake master cylinder.
- Check the brake fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4).
- Close the master cylinder cap securely.

3. Inspect Brake Lines and Components

Sub-steps:
- Visually inspect brake lines for rust, cracks, or leaks.
- Look at calipers for any signs of fluid leakage.
- If any leaks are found, replace the damaged brake line or caliper as necessary.

4. Bleed the Brake System

Sub-steps:
- Begin at the furthest brake from the master cylinder (usually the passenger rear).
- Attach a clear tubing to the bleeder valve and place the other end in a container.
- Have an assistant pump the brake pedal several times, then hold it down.
- Open the bleeder valve to allow fluid and air to escape, then close it.
- Repeat until no air bubbles are present, and then move to the next wheel.
- Ensure to top off the brake fluid reservoir after bleeding each brake line.

5. Replace Worn Brake Components (if necessary)

Sub-steps:
- If brake pads or rotors are worn, remove the wheel and inspect them.
- For brake pads, remove the caliper (using a socket set) and replace the pads.
- For rotors, remove the caliper, then the rotor retaining screws, and replace the rotor.
- Reinstall all components and torque to manufacturer specifications.
