Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder cap and inspect brake fluid level.
2. If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
3. If the fluid is dark or contaminated, proceed to replace it.
4. Use a brake bleeder kit to flush old fluid from the system.

3. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect brake lines for corrosion, cracks, or leaks.
2. If any damage is found, replace the affected brake lines.
3. Ensure all connections are tight and secure.

4. Bleed the Brake System

Sub-steps:
1. Begin with the wheel farthest from the master cylinder (usually the rear passenger side).
2. Attach a bleeder hose to the brake caliper bleeder valve and place it in a container.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and old fluid, then close it before the assistant releases the pedal.
5. Repeat until clear fluid without bubbles flows out, then move to the next wheel.

5. Inspect Brake Components

Sub-steps:
1. Remove the wheel and inspect brake pads for wear; replace them if less than 3mm thick.
2. Check rotors for grooves or warping; replace if necessary.
3. Ensure calipers are functioning properly; replace if leaking or sticking.

6. Test Drive and Final Inspection

Sub-steps:
1. Reassemble any components removed and replace the master cylinder cap.
2. Test drive the vehicle to ensure brakes respond correctly.
3. Check for any leaks or abnormal noises after the test drive.
