Solution

1. Preparation

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

2. Inspect and Replace Brake Fluid

• Tools Required: Brake fluid, funnel, and clean rags.
• Sub-steps:
  1. Open the brake fluid reservoir cap.
  2. If the fluid is low, add the appropriate brake fluid type as specified in the owner's manual (usually DOT 3 or DOT 4).
  3. Clean any spilled fluid with a rag to prevent damage to vehicle surfaces.

3. Brake Line Inspection and Repair

• Tools Required: Wrench set, brake line wrench, and possibly replacement brake lines or fittings.
• Sub-steps:
  1. Inspect all brake lines and hoses for cracks, corrosion, or fluid leaks.
  2. If leaks are found, replace the damaged sections of brake line or hose using the brake line wrench.
  3. Ensure all connections are tight and leak-free after replacement.

4. Bleed the Brake System

• Tools Required: Brake bleeder kit, clear tubing, and a container to catch old fluid.
• Sub-steps:
  1. Start at the wheel furthest from the master cylinder (usually the passenger rear).
  2. Attach the clear tubing to the bleeder valve and place the other end in the container.
  3. Have an assistant press the brake pedal while you open the bleeder valve. Close it before the pedal is released.
  4. Repeat until no air bubbles are present in the fluid.
  5. Move to the next wheel and repeat until all four brakes have been bled.

5. Replace or Repair Master Cylinder (if necessary)

• Tools Required: Socket set, torque wrench, and possibly a new master cylinder.
• Sub-steps:
  1. Disconnect the brake lines from the master cylinder using a line wrench.
  2. Remove the master cylinder mounting bolts and carefully take it out.
