2001 Pontiac Grand Am.?

[Justin G]

I have an 01 Grand Am. My ABS, Traction control, and Service Vehicle Light are all on. I recently just changed my FRONT brake pads and rotors. My BRAKE light comes on now. I know a year ago the light came on and I had the front wheel bearings changed.

Are there wheel bearings in the rear wheels?

And why would the BRAKE light be coming on?

I am a single Dad who is runnin out of money... Anyones help would be greatly greatly appreciated.

There are wheel bearings with speed sensors in the rear. I'd take a quick look at the front where you were working to make sure you didn't unhook or damage the wheel speed sensor wiring.

Beyond that, do you have a multimeter? If you jack the rear up and support it, you can probe the sensor wires for voltage. Spin each wheel/tire at a controlled speed by hand (maybe a few different speeds), and compare the voltage behaviors to eachother. One might stand out for having erratic voltage or none at all.
