Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves before starting the procedure.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
3. If low, use a funnel to add the appropriate type of brake fluid (usually DOT 3 or DOT 4).
4. Replace the cap securely after refilling.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line wrench
Sub-steps:
1. Inspect all brake lines for signs of corrosion or damage.
2. Tighten any loose fittings using the appropriate wrench.
3. If a leak is detected, replace the damaged brake line or fitting as necessary.
4. Ensure all connections are secure to prevent future leaks.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing
Sub-steps:
1. Start at the wheel farthest from the master cylinder (usually the right rear).
2. Attach the clear tubing to the bleeder valve on the brake caliper.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid, then close it while the pedal is held down.
5. Repeat the process until no air bubbles are seen in the fluid.
6. Move to the left rear, right front, and finally the left front wheel, repeating the bleeding process at each caliper.

5. Test Brake Functionality

Sub-steps:
1. After bleeding the brakes, check the brake fluid level again and top off if necessary.
2. Start the vehicle and test the brake pedal for firmness.
3. Conduct a slow test drive in a safe area to ensure brakes engage properly.
