Solution

1. Preparation

Tools Required: Socket set, wrench set, brake cleaner, rags, safety goggles, gloves.
Ensure the vehicle is parked on a level surface and the engine is off.
Put on safety goggles and gloves for protection.

2. Locate the Leak

Use the brake cleaner to clean any visible brake fluid residue.
Inspect the brake fluid reservoir for cracks or leaks; replace if damaged.
Check brake lines for any signs of damage or corrosion; repair or replace as necessary.

3. Repair or Replace Affected Components

Brake Lines:
- If damaged, use a wrench to disconnect the affected line at both ends.
- Measure and cut a new brake line to the appropriate length.
- Install the new brake line, ensuring all fittings are tight and secure.
Brake Calipers/Wheel Cylinders:
- If leaking, remove the wheel and caliper or drum to access the cylinder.
- Replace any faulty seals or gaskets.
- Reassemble and ensure proper torque specifications are followed (typically 20-25 ft-lbs for caliper bolts).
Master Cylinder:
- If the master cylinder is leaking, disconnect brake lines and remove the mounting bolts.
- Install the new master cylinder and reconnect brake lines, ensuring they are secure.

4. Refill and Bleed the Brake System

Refill the brake fluid reservoir with the recommended brake fluid (DOT 3 or DOT 4).
Bleed the brake system to remove any air using the brake bleeder kit, starting from the farthest wheel from the master cylinder.
