Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Check Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check fluid level; refill with manufacturer-recommended brake fluid if low.
3. Inspect fluid for contamination (dark color or debris).

3. Inspect for Leaks

Sub-steps:
1. Visually inspect all brake lines, hoses, and fittings for signs of fluid leaks.
2. Check around the wheel wells and under the vehicle for wet spots or fluid puddles.
3. If leaks are found, replace the damaged components.

4. Bleed Brake System

Sub-steps:
1. Locate the brake bleeder valves on each brake caliper.
2. Use a wrench to open the valve slightly while a helper presses the brake pedal.
3. Allow fluid to escape until air bubbles are no longer visible, then close the valve.
4. Repeat for each caliper, starting from the furthest from the master cylinder to the closest.
5. Ensure the brake fluid reservoir is kept topped up during the process to avoid introducing more air.

5. Reassemble and Test

Sub-steps:
1. Recheck the brake fluid level and top off if necessary.
2. Reconnect the battery and start the vehicle.
3. Press the brake pedal several times to ensure it feels firm.
4. Conduct a test drive to verify brake performance.
