Solution

1. Preparation

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

2. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line flare tool, brake line cutter.
Inspect the brake lines for any signs of corrosion or damage.
If a leak is found, determine the length of the damaged section.
Use the brake line cutter to remove the damaged portion.
Replace it with a new brake line and use the flare tool to create secure fittings.

3. Replace or Repair Brake Components

Tools Required: Socket set, torque wrench.
Inspect brake calipers, wheel cylinders, and master cylinder for leaks.
If any component is leaking, remove it from the vehicle:
- Unscrew the mounting bolts using the socket set.
- Disconnect the brake line from the component.
Replace with a new component or rebuild if applicable, ensuring proper sealing.
Reattach the brake line and tighten to manufacturer specifications.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, container for old brake fluid.
Begin by filling the master cylinder reservoir with new brake fluid (DOT 3 or DOT 4 as specified).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder screw on the farthest brake caliper from the master cylinder.
Allow old fluid and air to escape until a steady stream of fluid flows, then close the bleeder screw.
Repeat the process for each brake caliper, moving from farthest to closest to the master cylinder.

5. Final Checks and Reassembly

Recheck brake fluid level in the master cylinder and top off as needed.
Ensure all connections are tight and secure.
Reinstall any components or covers removed during the process.
