ABS & E BRAKE LIGHT

I have a 99 grand am GT and my abs light and e brake light always come on.. only when put the car in drive or press the brake..
ive heard many different things that it could be (ie speed sensor, brakes, abs, bearing etc..)
Any other ideas what it would be?
Im taking it to my mechanic sometime this week i just havent had time. Does anyone think that it could be serious enough for me not to be driving the rest of the week?
Thanks in advanced

Is your speedometer working and do the brakes engage normally or do they feel spongie?. One good rule to follow when in doubt about a brakes issue. take public transportation til its fixed.

Yes my speedo works fine..
I have been taking the Go train and PT recently..
but i just want to get an idea of what else could be wrong so i know roughly how much ill be spending

The Abs & Trac Low Lights Were On In My Car - There Was Also Grinding When Turning Left- Turned Out That It Was The Wheel Bearing On Front Right Side- The Hub Had To Be Replaced

Oh Yeah! The Hub Cost Me About $500.00

Thanks for all your replys.. i took it to my mechanic.. and yes it did turn out to be a bearing same tire as yours .
STUPID POT HOLES!!!
