Solution

1. Preparation

Gather tools and materials: Brake fluid, brake bleeder kit, wrench set, and safety gear (gloves, goggles).
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level.
If low, top off with the appropriate brake fluid (consult the owner's manual for specifications).

3. Inspect for Leaks

Visually inspect all brake lines, the master cylinder, and brake calipers for any signs of fluid leakage.
If leaks are found, replace the affected components with OEM parts.

4. Bleed the Brake System

Attach the brake bleeder kit to the brake bleeder valve on each brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close it before the pedal is released.
Repeat until no air bubbles are visible in the fluid.
Start with the brake furthest from the master cylinder (usually the rear passenger side) and move to the nearest (front driver side).

5. Test Brake Components

After bleeding the brakes, press the brake pedal several times to ensure it feels firm and responsive.
Inspect the brake pads and rotors; replace if worn beyond specifications.
