Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative terminal of the battery.

2. Check Brake Fluid Level

Locate the brake fluid reservoir (typically near the driver's side).
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with manufacturer-recommended brake fluid (usually DOT 3 or DOT 4).

3. Inspect Brake System

Visually inspect brake lines and hoses for any signs of leaks or damage.
Look for fluid stains around the brake calipers and wheel cylinders.
Check brake pads for wear; replace if they are below the recommended thickness (usually 3mm).

4. Replace Components (if necessary)

If brake pads are worn, remove the wheel using a socket set.
- Remove caliper bolts and slide the caliper off.
- Replace brake pads and reassemble the caliper.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 80-100 lb-ft).
If brake fluid leaks are found, replace damaged hoses or lines as necessary.

5. Reconnect Battery and Reset Warning Light

Reconnect the negative terminal of the battery.
Start the vehicle and check if the brake warning light is still illuminated.
If the light remains on, use an OBD-II scanner to clear any stored codes.
