What does it mean if the "Brake System" warning light comes on in my 2019 Camry?

Possible Causes

1. Low Brake Fluid Level: This can trigger the warning light.
2. Worn Brake Pads: If the pads are worn down, the sensor may activate the warning.
3. Faulty Brake System Components: This includes master cylinder issues or brake lines.
4. ABS Malfunction: Problems with the anti-lock braking system can also cause the warning light.
5. Parking Brake Engaged: If the parking brake is engaged, the light will stay on.
