If you notice the brake light on your Prius is on, it’s best to get it checked by a professional mechanic to ensure the safety of yourself and others on the road.
Common Reasons For Prius Brake Light On
Here are some common reasons why the brake light on your Prius may be on:
1. Low Brake Fluid Level
If your brake fluid level is low, it can cause the brake warning light to come on. This can be due to a leak in the brake system, worn brake pads, or a faulty master cylinder.
2. Faulty Brake Switch
A faulty brake light switch can also cause the brake light to remain on even if the brake pedal is not pressed. This can occur due to a faulty switch, loose wiring, or a bad connection.
3. ABS System Issues
If there’s a problem with your Anti-lock Braking System (ABS), it can cause the brake light to come on. This may be due to a faulty sensor, a malfunctioning ABS module, or a problem with the ABS pump.
4. Parking Brake Engagement
If the parking brake is engaged, it can cause the brake light to remain on even if the brake pedal is not pressed. Make sure to disengage the parking brake before driving.

Worn brake pads can cause the brake warning light to come on. If the brake pads are excessively worn, they can damage the brake rotors and cause further problems.
