Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety goggles and gloves for protection.

2. Check Brake Fluid

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Remove the cap and check the fluid level. It should be between the minimum and maximum lines.
- If the fluid is low, top it off with the manufacturer-recommended brake fluid type.
Tools Required: Brake fluid, funnel.

3. Inspect Brake Lines and Hoses

Sub-steps:
- Examine all brake lines and hoses for cracks, bulges, or leaks.
- Tighten any loose connections and replace damaged lines or hoses as needed.
Tools Required: Wrench set, replacement brake lines.

4. Bleed the Brake System

Sub-steps:
- Starting with the wheel farthest from the master cylinder, remove the wheel and locate the brake bleeder valve.
- Attach a clear hose to the bleeder valve and submerge the other end in a container filled with brake fluid.
- Have an assistant press the brake pedal several times and hold it down. Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal.
- Repeat this process for each wheel, moving from farthest to closest to the master cylinder.
Tools Required: Brake bleeder kit, wrench for bleeder valve.

5. Inspect and Replace Brake Components

Sub-steps:
- Remove the wheel and inspect brake pads for wear. Replace if they are worn down to the indicators.
- Check rotors for warping or scoring; replace if necessary.
- If the master cylinder is found to be faulty, remove it and replace it with a new unit.
Tools Required: Socket set, jack, jack stands, brake pads, rotors (if needed).
