Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Inspect and Repair Leaks

Sub-steps:
1. Locate any leaks by inspecting all brake lines, connections, and components.
2. If a leak is found, replace the damaged brake line or component (e.g., caliper, wheel cylinder).
3. Use a brake line wrench to loosen and remove the affected section.
4. Install the new part and tighten to manufacturer specifications (typically around 15-20 ft-lbs for brake line fittings).

3. Bleed the Brake System

Sub-steps:
1. Connect a brake bleeder kit to the brake bleeder valve on the farthest wheel from the master cylinder.
2. Open the bleeder valve and have an assistant press the brake pedal.
3. Close the valve before the pedal is released to prevent air from entering the system.
4. Repeat until no air bubbles appear in the fluid, then move to the next wheel.
5. Ensure the master cylinder remains filled with brake fluid throughout the process.

4. Replace Brake Fluid (if necessary)

Sub-steps:
1. If the brake fluid is contaminated or low, remove the master cylinder cap.
2. Use a turkey baster to extract old fluid from the reservoir.
3. Refill with fresh brake fluid (DOT 3 or DOT 4, as specified in the owner's manual).
4. Reinstall the master cylinder cap securely.

5. Reassemble and Test

Sub-steps:
1. Recheck all connections for tightness.
2. Test the brake pedal feel while the engine is running.
3. Conduct a slow test drive to ensure brakes are functioning correctly without any unusual noises.
