If something was wrong with abs, wouldn't the light be on? brakes sticking...cont.?

it all depends on what type of failure that the abs is having if any. if your brakes are sticking i would look into possible binding of the guide pins that the calipers ride on, trapped air in the system, hose/ caliper. would also look at the break hose itself to see if there is a possible bad hose. this can be done internally on the hose. before ruleing that the abs mod. is bad have a shop do a scan of the abs and see if it shows any problems.
