Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

Tools Required:

Socket set
Brake line wrench
Brake bleeder kit
Torque wrench
Multimeter (if checking electrical components)

2. Inspect and Repair Leaks

Sub-steps:
1. Locate any leaks in the brake lines, calipers, or master cylinder.
2. If leaks are found, use a brake line wrench to disconnect the affected line.
3. Replace damaged brake lines or calipers as necessary.
4. Reconnect lines and ensure all fittings are tight.

3. Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder reservoir cap and clean the area around it.
2. Use a brake bleeder kit to suck out old fluid from the reservoir.
3. Fill the reservoir with new brake fluid (DOT 3 or DOT 4 as specified).
4. Reinstall the reservoir cap securely.

4. Bleed the Brakes

Sub-steps:
1. Start with the wheel farthest from the master cylinder (usually the right rear).
2. Attach the brake bleeder kit to the bleeder valve on the brake caliper.
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 while the pedal is held down.
5. Repeat the process at each wheel in the following order: right rear, left rear, right front, left front.
6. Monitor the fluid level in the master cylinder and top off as necessary during the process.

5. Final Assembly and Testing

Sub-steps:
1. Once bleeding is complete, ensure all bleeder valves are closed.
2. Recheck the fluid level in the master cylinder and top off if required.
3. Start the vehicle and press the brake pedal to ensure it feels firm.
4. Test drive the vehicle to ensure proper braking performance.
