Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off and the parking brake engaged.
Wear safety glasses and gloves.

2. Inspect and Repair Brake Lines

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Visually inspect brake lines for any leaks or corrosion.
- If leaks are found, replace the damaged brake line sections using appropriate fittings.
Tools Required: Wrench set, brake line flaring tool (if necessary), brake line replacement parts.

3. Check and Replace Brake Master Cylinder

Sub-steps:
- Disconnect the battery to ensure safety.
- Remove the brake fluid reservoir cap and siphon out any remaining fluid.
- Disconnect brake lines from the master cylinder and remove any mounting bolts.
- Install a new brake master cylinder by reversing the removal steps. Ensure all connections are tight to prevent leaks.
Tools Required: Socket set, wrench set, brake fluid.

4. Bleed the Brake System

Sub-steps:
- Start at the brake furthest from the master cylinder (usually the passenger rear) and work towards the nearest (driver front).
- Attach a clear plastic hose to the bleeder valve and submerge the other end in a container of brake fluid.
- Have an assistant pump the brake pedal and hold it down while you open the bleeder valve to release air and fluid. Close the valve before the assistant releases the pedal.
- Repeat until no air bubbles are visible in the fluid.
Tools Required: Brake bleeder kit, clear plastic hose, container for fluid.
