Hello,

Did you have this warning light before the brake replacement?
And the warning light that is on, is it for the parking brake light or the low brake light or the ABS light?

It could be due to a sensor not being plugged in properly or a number of faulty components.

Let me know a few more details of what you are experiencing. You can also upload pictures of the light that is illuminated.

Thank you.

The light was not on prior to the brake replacement. The light is the parking brake/ brake fluids light on the dash. I have checked to make sure that the parking brake is off. The light comes on after about 5 minutes of driving and stays in the on position until the car is turned off. Then it seems to reset and starts again after about 5 minutes of driving.

One of the possibilities is an issue with the master cylinder. Just to make sure, have you checked the fluid level and verify that it is correct?
The brake light can also get triggered due to a fault with the brake proportioning valve or the module.
