Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Ensure the vehicle is parked on a level surface and secure with wheel chocks.
  • Wear safety goggles and gloves.
2. Check and Refill Brake Fluid
  • Locate the master cylinder reservoir, typically found near the back of the engine bay.
  • Remove the cap and check the fluid level; if low, top up with the appropriate brake fluid (DOT 4 recommended).
  • Inspect for any signs of contamination in the fluid.
3. Inspect and Repair Brake Lines
  • Visually inspect all brake lines for signs of wear, corrosion, or leaks.
  • If leaks are found, replace the damaged brake line using a wrench and appropriate brake line fittings.
  • Ensure all connections are tight and secure.
4. Bleed the Brakes
  • Start at the wheel furthest from the master cylinder (usually the passenger-side rear).
  • Use a brake bleeder kit or clear tubing attached to the bleeder valve.
  • Open the valve, have an assistant press the brake pedal, and close the valve before releasing the pedal.
  • Repeat until no air bubbles are observed in the fluid.
  • Move to the next wheels in the following order: driver-side rear, passenger-side front, and driver-side front.
5. Replace the Brake Master Cylinder (if necessary)
  • If the master cylinder is found to be faulty, remove it by disconnecting the brake lines and unbolting from the brake booster.
  • Install the new master cylinder, ensuring all connections are sealed and tightened.
  • Refill brake fluid and bleed the system as described earlier.
