Solution

1. Preparation

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

2. Check and Refill Brake Fluid

Sub-steps:
1. Open the hood and locate the brake master cylinder.
2. Remove the cap and check the fluid level.
3. If low, top off with the manufacturer's recommended brake fluid (typically DOT 3 or DOT 4).
4. Replace the cap securely.

3. Inspect for Leaks

Sub-steps:
1. Visually inspect all brake lines, hoses, calipers, and wheel cylinders for signs of fluid leakage.
2. If leaks are found, replace affected components (e.g., brake lines, calipers).

4. Bleed the Brake System

Sub-steps:
1. Locate the brake bleeder valves on each wheel.
2. Starting from the wheel farthest from the master cylinder, attach a clear hose to the bleeder valve.
3. Have an assistant press the brake pedal repeatedly and hold it down.
4. Open the bleeder valve to allow air and fluid to escape, then close it.
5. Repeat until no air bubbles are visible in the fluid.
6. Move to the next closest wheel and repeat.

5. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake components.
2. Check the brake pads for thickness; replace if below the manufacturer's specifications (typically 3mm).
3. Inspect rotors for warping or scoring; resurface or replace as needed.
4. Reassemble the brake components and wheel securely.
