Solution

1. Preparation

Gather 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. Inspect and Replace Brake Fluid

Sub-steps:
- Remove the master cylinder reservoir cap.
- Check the brake fluid condition; if it is dark or contaminated, drain the system.
- Use a brake fluid bleeder kit to remove old fluid from all brake lines.
- Refill with manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).
- Replace the master cylinder cap and ensure it is secure.

3. Check and Repair Brake Lines

Sub-steps:
- Visually inspect all brake lines for corrosion, damage, or leaks.
- If leaks are found, replace the affected brake lines using a line wrench.
- Ensure all connections are tight and free from leaks.

4. Inspect and Replace Brake Components

Sub-steps:
- Remove the wheel to access the brake caliper and rotor.
- Inspect brake pads for thickness; replace if they are below 3mm.
- Check rotors for scoring or warping; replace if necessary.
- Reassemble the brake components and wheel.

5. Test and Bleed Brake System

Sub-steps:
- Connect a brake bleeder kit to the bleeder valve on each caliper.
- Have an assistant pump the brake pedal to build pressure.
- Open the bleeder valve to release air and fluid until no bubbles are present.
- Repeat for all calipers until the brake pedal feels firm.
- Recheck fluid levels in the master cylinder and top off as needed.
