Solution

1. Preparation

Tools Required: Wrench set, socket set, brake fluid, clean rags, brake line wrench, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Locate the Leak

Sub-steps:
- Begin by inspecting the brake fluid reservoir. If it is cracked, replace it.
- Trace the brake lines from the master cylinder to the wheels, looking for any visible damage.

3. Repair or Replace Damaged Components

Sub-steps:
- If a brake line is damaged, use a brake line wrench to disconnect the affected section. Cut a new section of brake line to the appropriate length.
- Flare the ends of the new brake line if necessary and connect it to the existing line using appropriate fittings. Ensure all connections are tight.
- For leaking calipers, remove the wheel and caliper. Inspect the caliper seals. If damaged, replace the caliper or rebuild it with new seals.
- If the master cylinder is leaking, first remove the brake fluid from the reservoir, then unbolt the master cylinder from the brake booster. Replace it with a new unit, ensuring all connections are secure.

4. Bleed the Brake System

Sub-steps:
- Fill the brake fluid reservoir with new brake fluid up to the recommended level.
- Starting at the wheel furthest from the master cylinder, use a brake bleeder kit to bleed air from each brake line until clear fluid flows without bubbles.
- Repeat for all wheels, checking fluid levels throughout the process.
