Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Repair Leaks

Sub-steps:
1. Visually inspect all brake lines, the master cylinder, and brake calipers for any signs of fluid leaks.
2. If leaks are found, replace the damaged brake line or caliper as necessary.
3. Replace the master cylinder if it is leaking or malfunctioning.
Tools Required: Wrench set, jack and jack stands, brake line flaring tool (if needed)

3. Bleed the Brake System

Sub-steps:
1. Refill the master cylinder with fresh brake fluid.
2. Starting with the wheel farthest from the master cylinder, attach a brake bleeder kit to the bleeder valve on the caliper.
3. Pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid, close the valve, then release the pedal.
5. Repeat until no air bubbles are visible in the fluid, then move to the next wheel.
Tools Required: Brake bleeder kit, wrench for bleeder valves, brake fluid

4. Reassemble and Test

Sub-steps:
1. Reinstall any components removed during the process.
2. Reconnect the battery.
3. Test the brake pedal for firmness; it should not sink to the floor.
