Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear gloves and safety goggles.

2. Inspect and Replace Damaged Components

Sub-steps:
1. Check Brake Reservoir:
  - Remove the cap from the brake fluid reservoir.
  - Inspect for cracks; replace if damaged.
2. Inspect Brake Lines:
  - Visually inspect all brake lines for leaks.
  - If leaks are found, replace the affected line or fitting.
3. Check Calipers and Wheel Cylinders:
  - Remove the wheel to access brake calipers.
  - Inspect for fluid around the calipers; replace if leaking.
4. Inspect Master Cylinder:
  - Remove the master cylinder from the brake booster.
  - Check for leaks at the seals; replace if necessary.

3. Refill and Bleed Brake System

Sub-steps:
1. Refill Brake Fluid:
  - Use the appropriate brake fluid as specified in the owner’s manual.
  - Fill the reservoir to the recommended level.
2. Bleed the Brakes:
  - Start with the wheel farthest from the master cylinder.
  - Attach a clear tube to the bleeder valve and submerge it in a container.
  - Open the valve and pump the brake pedal until no air bubbles appear.
  - Repeat for each wheel, ensuring fluid levels remain adequate.
