Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Tools Required: Brake fluid, socket set, wrench set, brake line wrench, brake cleaner, clean rags, safety glasses, gloves.

2. Identify and Replace Damaged Components

Brake Fluid Reservoir:
- Remove the cap and inspect for cracks. If damaged, replace it.
Brake Lines:
- Use a brake line wrench to disconnect any damaged lines. Replace with new lines as necessary, ensuring all connections are tight and sealed.
Brake Caliper:
- Remove the wheel to access the caliper. Inspect for leaks; if leaking, replace the caliper and bleed the brakes after installation.
Master Cylinder:
- Remove the master cylinder (may require disconnecting brake lines). Inspect for leaks; replace if necessary. Reconnect and refill with brake fluid.
Wheel Cylinder (if applicable):
- For vehicles with drum brakes, remove the drum and inspect the wheel cylinder. Replace if leaking.

3. Bleed the Brake System

Start at the wheel farthest from the master cylinder. Open the bleeder valve, and have an assistant pump the brake pedal until fluid flows without bubbles. Close the valve and repeat for all wheels.
