Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a flat surface and secure the vehicle with wheel chocks.
Tools Required:
- Brake fluid
- OBD-II scanner (if warning light is present)
- Wrench set
- Brake bleeder kit
- Torque wrench
Safety Warnings:
- Always wear safety glasses and gloves when working with brake fluid, as it can damage paint and is harmful to skin.

2. Inspect and Refill Brake Fluid

Remove the cap from the brake fluid reservoir.
Check the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely.

3. Bleed the Brake System

Begin at the wheel farthest from the master cylinder (usually the right rear).
Use a brake bleeder kit and connect it to the brake bleeder valve on the caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to allow fluid and air to escape, then close it before your assistant releases the pedal.
Repeat this process until the fluid runs clear and free of bubbles, then proceed to the next wheel in the order: right rear, left rear, right front, left front.

4. Inspect and Replace Components (if needed)

Check the master cylinder for signs of fluid leakage. If leaking, replace the master cylinder.
Inspect brake calipers for leaks or damage; replace if necessary.
If brake lines are compromised, replace them using the appropriate line fittings and ensuring proper routing.

5. Final Assembly and Testing

Ensure all components are securely tightened to manufacturer specifications using a torque wrench.
Refill the brake fluid reservoir to the recommended level.
Test the brake pedal for firmness before driving.
