Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Check and Replace Brake Fluid

Sub-steps:
1. Open the master cylinder reservoir cap.
2. Inspect brake fluid condition; if dirty or low, proceed with a fluid change.
3. Using a turkey baster, remove old brake fluid from the reservoir.
4. Refill with new, manufacturer-recommended brake fluid (DOT 3 or DOT 4).
5. Replace the reservoir cap securely.

3. Inspect and Repair Brake Lines

Sub-steps:
1. Visually inspect all brake lines for signs of leaks or damage.
2. If leaks are found, replace the damaged brake line(s).
3. Use a brake line flaring tool to create appropriate connections if needed.
4. Ensure all connections are tight and secure to prevent future leaks.

4. Bleed the Brake System

Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the right rear).
2. Attach a clear hose to the bleeder valve and submerge the other end in a container with brake fluid.
3. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
4. Close the valve before the pedal is released.
5. Repeat until no air bubbles are present, then move to the left rear, right front, and finally left front.
6. Confirm brake fluid levels are maintained during the process.

5. Inspect and Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake pads for thickness; replace if less than 3mm.
3. Measure rotor thickness and look for warping; replace if below specifications.
4. Install new pads and rotors as needed, following manufacturer specifications.
5. Torque mounting bolts to the specified values.
