Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Put on safety glasses and gloves.

2. Inspect and Identify Leak Source

Check Brake Fluid Reservoir:
- Open the hood and locate the brake fluid reservoir.
- Inspect for cracks or damage; replace if necessary.
Examine Brake Lines:
- Visually inspect all brake lines for corrosion or signs of wear.
- Tighten any loose connections or replace damaged lines.

3. Repair or Replace Components

Calipers and Wheel Cylinders:
- If leakage is found at the calipers or wheel cylinders, remove the affected component.
- Replace seals or the entire caliper/wheel cylinder as necessary.
Master Cylinder Replacement:
- If the master cylinder is leaking, disconnect the brake lines and electrical connectors.
- Remove the master cylinder from its mounting bracket.
- Install the new master cylinder, ensuring proper torque specifications.

4. Refill and Bleed Brake System

Refill Brake Fluid:
- Fill the brake fluid reservoir with the recommended fluid type (DOT 3 or DOT 4, depending on specifications).
Bleed the Brake System:
- Starting from the wheel farthest from the master cylinder, attach a bleeder hose to the caliper bleeder screw.
- Open the screw while a helper presses the brake pedal. Close the screw before releasing the pedal. Repeat until no bubbles appear.
- Repeat for all wheels in the proper sequence.
