Solution
1. Preparation
  • Gather tools and parts needed.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Wear safety goggles and gloves.
2. Check and Refill Brake Fluid
  • Sub-steps:
    • Open the hood and locate the brake master cylinder.
    • Check the brake fluid level; if low, top off with the recommended brake fluid (DOT 3 or DOT 4).
    • Inspect for any signs of leaks around the reservoir cap.
3. Inspect and Repair Leaks
  • Sub-steps:
    • Visually inspect all brake lines, hoses, and connections for leaks.
    • If any leaks are found, replace the damaged sections of the brake line or hose.
    • Tighten any loose fittings and replace any worn seals or components.
4. Replace Master Cylinder (if necessary)
  • Sub-steps:
    • Disconnect the negative battery terminal.
    • Remove the brake fluid from the master cylinder reservoir.
    • Unbolt and remove the master cylinder from the brake booster.
    • Install a new master cylinder, using the manufacturer's specifications for torque.
    • Reconnect the brake lines and refill the reservoir with brake fluid.
5. Bleed the Brake System
  • Sub-steps:
    • Begin at the furthest brake caliper from the master cylinder (typically the rear passenger side).
    • Use a brake bleeder kit or a helper to pump the brake pedal while you open the bleeder valve.
    • Close the valve before releasing the pedal to avoid air intake. Repeat until no air bubbles are visible.
    • Proceed to the remaining calipers in the order: rear driver, front passenger, and finally front driver.
