Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to ensure safety while working on the braking system.

2. Check and Refill Brake Fluid

Locate the brake fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Replace the cap securely.

3. Inspect and Replace Brake Pads (if necessary)

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; if less than 3mm, replace.
Use a socket set to remove the caliper bolts and slide the caliper off the rotor.
Replace the pads with new ones, ensuring proper alignment.
Reattach the caliper and torque bolts to the manufacturer's specification.

4. Check Brake Lines and Hoses

Visually inspect brake lines for cracks or leaks.
If any leaks are found, replace the damaged line or hose.
Ensure all connections are tight and free of corrosion.

5. Check ABS Sensor

Locate the ABS sensor on the wheel hub.
Inspect the wiring for frays or disconnections.
Clean the sensor area with a brake cleaner if necessary, and reattach any loose connections.

6. Reconnect Battery and Test

Reconnect the battery terminal.
Start the vehicle and check if the brake warning light is still illuminated.
Test brake performance by applying the brakes at low speeds.
