Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and securely lift it using jack stands.
  • Disconnect the negative battery terminal to prevent electrical issues.
2. Inspect and Repair Brake Lines
  • Sub-steps:
    • Visually inspect all brake lines for corrosion, cracks, or damage.
    • If leaks are found, mark the damaged sections for replacement.
    • Use a line wrench to disconnect the damaged brake line at the fittings.
    • Replace the damaged line with a new one, ensuring all connections are tight.

Tools Required: Brake line wrench, cutting tool, flaring tool (if necessary).

3. Replace or Refill Brake Fluid
  • Sub-steps:
    • If brake fluid is low, refill it with the manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).
    • If there are signs of contamination or if the fluid is discolored, completely flush the brake fluid system.
    • Use a brake bleeder kit to flush fluid from each brake caliper starting from the furthest from the master cylinder and moving to the nearest.

Tools Required: Brake bleeder kit, proper brake fluid.

4. Repair or Replace Master Cylinder
  • Sub-steps:
    • If the master cylinder is suspected to be faulty, remove it from the vehicle.
    • Disconnect the brake lines and electrical connectors (if equipped).
    • Inspect the master cylinder for signs of fluid leakage and damage.
    • Replace it with a new master cylinder if necessary, following manufacturer specifications for installation.

Tools Required: Socket set, line wrench, torque wrench.

5. Inspect and Replace Brake Pads and Rotors (if necessary)
  • Sub-steps:
    • Remove the wheel to access the brake assembly.
    • Inspect the brake pads for wear (should be at least 3mm thickness).
    • Measure the rotor thickness and look for signs of warping or scoring.
    • Replace pads and rotors if they do not meet specifications.

Tools Required: Lug wrench, jack stands, socket set, torque wrench.
