i'm not real sure if this qualifies as a 911 emergency, but my abs light and brake warning lights on the dash have been on all day. at first i thought to check power steering fluid, thinking that if it was low these lights might come on. i checked it, found it to be low, and added a bit. the lights went off for a bit, but were back on this morning. i'd rather have you guys tell me what's wrong than pay someone else to... what could it be? (and is it safe to drive?)
