Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety glasses and gloves.

2. Inspect and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if low, top it off with the recommended brake fluid type (DOT 3 or DOT 4).
Replace the cap securely.

3. Inspect Brake Components

Check the brake lines for leaks or damage. Look for wet spots or corrosion.
Inspect the brake master cylinder for any visible leaks or signs of failure. If leaking, the master cylinder must be replaced.

4. Bleed the Brake System

Start at the furthest wheel from the master cylinder (usually the passenger rear).
Attach a clear hose to the bleeder valve on the brake caliper.
Have an assistant press the brake pedal while you open the bleeder valve slightly. Close the valve before the pedal reaches the floor and instruct your assistant to release the pedal.
Repeat this process until no air bubbles are observed in the fluid and fluid runs clear.
Move to the next wheel and repeat (driver rear, passenger front, driver front).

5. Test Brake Function

After bleeding, check the brake pedal feel by pressing it several times.
If the pedal feels firm, the bleeding was successful.
