Solution

1. Preparation

  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and secure it with wheel chocks.
  • Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

  • Sub-steps:
    1. Remove the brake fluid reservoir cap.
    2. If the fluid is low, refill it with the recommended brake fluid (DOT 4).
    3. If the fluid appears contaminated, drain the system.
    4. Bleed the brake system to remove air bubbles.
  • Tools Required: Brake fluid, funnel, brake bleeder kit.

3. Inspect and Repair Brake Lines and Master Cylinder

  • Sub-steps:
    1. Visually inspect all brake lines and hoses for cracks, corrosion, or leaks.
    2. If any damage is found, replace the affected brake lines.
    3. Inspect the master cylinder for leaks or fluid seepage; replace if necessary.
    4. Tighten any loose fittings and ensure connections are secure.
  • Tools Required: Wrench set, pliers, brake line fittings.

4. Check and Replace Brake Pads and Rotors
