Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and turn off the engine.
Wear safety gloves and goggles.

2. Inspect and Clean

Tools Required: Brake cleaner, rags
Visually inspect the brake lines, calipers, and master cylinder for leaks.
Clean any spilled brake fluid from the surrounding areas with brake cleaner.

3. Refill Brake Fluid

Tools Required: Funnel
Remove the cap from the brake fluid reservoir.
Using a funnel, carefully add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) until the reservoir reaches the "full" mark.

4. Address Leaks

If any leaks are found during inspection, replace the damaged components (brake lines, calipers, or master cylinder) as necessary.
Sub-steps:
- Remove the affected component (e.g., brake line or caliper).
- Install the new component, ensuring all fittings are tight.
- Bleed the brake system to remove air from the lines.

5. Test Brake System

Start the engine and pump the brake pedal to build pressure.
Ensure that the brake pedal feels firm and there are no leaks present.
