Solution
1. Preparation
  • Gather tools: brake fluid, wrench set, socket set, brake cleaner, and safety glasses.
  • Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
  • Disconnect the battery to prevent electrical issues during repair.
2. Inspect and Repair Leaks
  • Sub-steps:
    1. Locate any visible leaks in the brake lines, calipers, and master cylinder.
    2. Tighten any loose connections with a wrench.
    3. If a brake line is damaged, replace the affected section with new brake line.
    4. If the master cylinder is leaking, remove it from the vehicle and replace it with a new one.
  • Tools Required: Wrench set, socket set, brake line flaring tool (if line replacement is necessary).
3. Bleed the Brake System
  • Sub-steps:
    1. Refill the master cylinder reservoir with fresh brake fluid.
    2. Start bleeding the brakes from the farthest wheel to the closest (right rear, left rear, right front, left front).
    3. Use a brake bleeder kit or have an assistant press the brake pedal while you open the bleeder valve on each caliper to release air.
    4. Close the valve before the pedal reaches the floor, then repeat until no air bubbles appear in the fluid.
  • Tools Required: Brake bleeder kit, wrench for bleeder valves.
4. Reassemble and Test
  • Sub-steps:
    1. Reconnect the battery.
    2. Start the vehicle and pump the brake pedal to ensure it firms up.
    3. Perform a test drive to confirm proper brake function.
  • Safety Warnings: Ensure all tools and materials are cleared from the vehicle before driving.
