Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to avoid electrical shorts.

2. Inspect and Repair Brake Lines

Tools Required: Wrench set, brake line flare tool, brake fluid.
Check for any damaged or corroded brake lines. If any are found, replace them:
1. Use a wrench to loosen the fittings on both ends of the damaged line.
2. Cut the old line and install a new brake line using a brake line flare tool for proper fittings.
3. Carefully bleed the brakes after replacing the line to remove air.

3. Brake Fluid Level and Master Cylinder Inspection

Tools Required: Funnel, brake fluid.
Check brake fluid level in the master cylinder:
1. If low, add the appropriate brake fluid (check owner’s manual for specification).
2. If the master cylinder is leaking, replace it:
  - Remove the brake line connections.
  - Unbolt the master cylinder from the brake booster.
  - Install the new master cylinder and reconnect the lines, ensuring no cross-threading occurs.

4. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, container.
To remove air from the brake lines:
1. Attach the tubing to the bleeder valve on the farthest brake caliper from the master cylinder.
2. Open the valve while a helper presses the brake pedal down.
3. Close the valve before the pedal is released and repeat until clear fluid without bubbles flows through.

5. Final Checks

Tools Required: Torque wrench (if applicable).
Recheck all connections and brake components:
1. Ensure all bolts are tightened to the manufacturer’s torque specifications.
2. Refill brake fluid to the proper level.
