Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Locate the Leak

Sub-steps:
- Inspect the brake fluid reservoir to determine the fluid level.
- Trace the brake lines from the master cylinder to all four wheels.
- Look for wet spots or corrosion on the brake lines, calipers, and master cylinder.

3. Replace Damaged Components

Sub-steps:
- If a brake line is damaged, use a line cutter to remove the affected section.
- Prepare new brake line (copper or steel) and bend it to match the original shape.
- Install the new line using appropriate fittings and torque specifications (typically around 14-18 ft-lbs).
If the brake caliper or wheel cylinder is leaking:
- Remove the wheel and brake caliper (torque specifications for caliper bolts are usually 25-35 ft-lbs).
- Replace the faulty caliper or wheel cylinder with a new one.
- Reinstall the caliper and ensure all bolts are torqued to specification.

4. Refill and Bleed the Brake System

Sub-steps:
- Refill the brake fluid reservoir with the manufacturer-recommended brake fluid (DOT 3 or DOT 4, as specified).
- Bleed the brake system using a brake bleeder kit or two-person method to remove any air bubbles.
- Start from the wheel farthest from the master cylinder and work toward the closest.
