Solution

1. Preparation

Gather necessary tools and materials.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Inspect Brake Fluid

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level; if low, fill with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
- If fluid is contaminated (discolored or cloudy), proceed to the next steps for a brake fluid flush.

3. Brake Bleeding

Sub-steps:
- Gather a brake bleeder kit and a wrench for the bleeder screws.
- Start with the wheel furthest from the master cylinder (usually the right rear).
- Attach the hose from the bleeder kit to the bleeder screw and place the other end in a container.
- Have an assistant pump the brake pedal several times and hold it down.
- Loosen the bleeder screw to allow air and fluid to escape; tighten the screw before the assistant releases the brake pedal.
- Repeat this process until no air bubbles are visible in the fluid, then move to the next wheel (left rear, right front, left front).

4. Inspect and Replace Worn Components

Sub-steps:
- Inspect brake pads and rotors for wear. Replace if pads are less than 3mm thick or if rotors are scored or warped.
- If the master cylinder is leaking or failing, remove the old master cylinder and replace it with a new one.

5. Final Checks

Sub-steps:
- Ensure all bleeder screws are tightened and that there are no leaks.
- Recheck the brake fluid level in the reservoir and top off if necessary.
- Test the brake pedal feel before road testing.
