Solution

1. Preparation

Tools Required: Brake fluid, socket set, brake bleeder kit, OBD-II scanner.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir under the hood.
Open the reservoir cap and check the fluid level against the "MIN" and "MAX" lines.
If low, add the appropriate brake fluid (typically DOT 3 or DOT 4 as recommended by the manufacturer) until it reaches the maximum level.
Replace the cap securely.

3. Inspect and Replace Brake Components (if necessary)

Remove the wheel corresponding to the affected brake (if pads/rotors need inspection).
Inspect the brake pads for thickness; replace if below the minimum specification.
Examine the rotors for scoring or damage; replace if necessary.
If components are worn, proceed to remove old pads/rotors using a socket set and install new ones, following the torque specifications provided in the service manual.

4. Bleed the Brake System

Attach the brake bleeder kit to the brake caliper furthest from the master cylinder.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder screw to allow air and old fluid to escape; close the screw before the pedal is released.
Repeat until clear fluid without bubbles appears, then move to the next caliper in the order of proximity to the master cylinder.
Ensure all bleeder screws are tightened and check fluid levels in the reservoir frequently to avoid running low.

5. Reset the Brake Warning Light

Connect the OBD-II scanner to the vehicle's diagnostic port.
Follow the scanner instructions to clear any error codes related to the brakes.
Disconnect the scanner and start the vehicle to ensure the warning light is off.
