Good afternoon.

Do you mean the ABS light and the red brake light?

The ABS system will turn on the light when there is a malfunction and will store a code for the area of failure.

You can go to a parts store and have the code read for free. Then when we have the code, we can further help you narrow the area of failure.

Okay, the red brake light means one of these:

1. Low fluid level in the master or a bad float switch in the master.

2. E-brake release not all the way released or the switch is bad. If it is on the floor, pull the pedal up with the back of your foot. If it is in the console, then push down the handle and see if the light goes out.

3. Pressure difference between the front and the rear of the normal brakes. If there is a pressure differential, the light will come on.
