Dash brake light

[ExplorerDan246]

Hello folks, I just replaced the drivers side front hub bearing unit I also replaced the driver side front rotor. I ran out of time but I will be replacing the passenger side rotor also. Immediately after the replacement the brake warning light came on and stayed on. Before the installation occasionally the ABS light would come on but never the brake light. I took another look at everything from where the sensor from the hub plugs in under the hood all the way down to the hub everything seems okay. I drove it and the brakes actually feel better than before and everything is quiet. Any ideas of what I need to look for? Thanks

Low brake fluid often caused by worn brake pads.

Brake system warning

Illumination after releasing the parking brake indicates low brake fluid level and the brake system should be inspected immediately.
