abs and rear brake problems? Options

[eclipse_04a]

ok, well i just got my car back, and actually drove it for the first time. i had both front axles replaced, but now, I have a noise coming from my rear brakes (not sure what side) when im driving. how do i tell if I have a warped rotor or something? also, my abs light is on when ever im driving.....im going to take it back to the place where i had it worked on and see whats up, and if its their fault, make them fix it. any ideas what it is? its just like a noise where the rotor has a kink and only makes noise as the one spot comes around....or is something wrong with my ABS and is trying grab....and thats whats making the noise.....its a 95 gt manual....i hope you guys can help.

its probably the pad wear indicator ....check in back and see if you need brakes in back....but as far as the light i dont think it would turn on because of that
