Solution

1. Preparation

Gather tools and materials needed:
- Wrench set
- Brake fluid
- Clean rags
- Container for old fluid
Ensure the vehicle is on a flat surface and secure with wheel chocks.

2. Locate and Fix the Leak

Brake Lines and Hoses:
- Inspect each section of the brake line and hose.
- Replace any that are damaged or corroded using a wrench and appropriate replacement lines.
Brake Calipers:
- Remove the wheel to access the brake caliper.
- Inspect for fluid around the caliper; if found, replace the caliper.
Master Cylinder:
- Check the master cylinder for leaks; if leaking, remove it by unscrewing the mounting bolts.
- Replace with a new master cylinder and bleed the brake system afterward.

3. Refill and Bleed the Brake System

Use new brake fluid to refill the reservoir.
Bleed the brake system to remove air bubbles:
- Start with the wheel furthest from the master cylinder and work towards the closest.
- Use a helper to press the brake pedal while you open and close the bleeder valve on each caliper until fluid flows without bubbles.
