Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Brake Fluid Inspection

Remove the brake fluid reservoir cap.
Inspect the fluid level; add manufacturer-recommended brake fluid (DOT 3 or DOT 4) if low.
If the fluid is dark or contaminated, perform a complete brake fluid flush.

3. Bleed Brake System

Reconnect the battery terminal.
Starting from the wheel farthest from the master cylinder (usually passenger side rear), use a brake bleeder kit or a helper to bleed the brakes.
1. Open the bleeder valve slightly.
2. Press the brake pedal until fluid flows out; close the valve while the pedal is down.
3. Release the pedal and repeat until no air bubbles are present.
Move to the next wheel and repeat the process until all brakes are bled.

4. Inspect ABS Components

Visually inspect all ABS sensors at each wheel for damage or loose connections.
Clean any dirt or debris from the sensor area.
Ensure that the wiring harness is intact and not frayed.

5. Clear Error Codes

Use an OBD-II scanner to clear any ABS error codes.
Recheck the ABS light status after clearing codes.
