Solution

1. Preparation

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

2. Inspect and Address Fluid Leaks

Sub-steps:
1. Visually inspect all brake lines, connections, and components for signs of fluid leakage.
2. If leaks are found, identify the source and determine if a line replacement or fitting repair is needed.
3. Clean the area around leaks for better visibility of any ongoing issues.

3. Replace Brake Fluid

Sub-steps:
1. Open the brake fluid reservoir cap.
2. Use a turkey baster or siphon to remove old brake fluid from the reservoir.
3. Refill the reservoir with the appropriate brake fluid type (DOT 3 or DOT 4).
4. Replace the reservoir cap securely.

4. Bleed the Brake System (if necessary)

Sub-steps:
1. Begin at the farthest brake from the master cylinder (usually the right rear).
2. Attach a clear plastic tube to the bleeder valve and place the other end in a container to catch fluid.
3. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid; close the valve before they release the pedal.
4. Repeat until there are no air bubbles in the fluid.
5. Move to the next brake in the sequence: left rear, right front, and finally left front.

5. Recheck Fluid Level and Perform Final Checks

Sub-steps:
1. After bleeding, check the brake fluid level again and top off if necessary.
2. Inspect all components for proper assembly and tighten any loose fittings.
3. Test the brake function before driving.
