hey new to this forum. I'm trying to get my father-in-laws van figured out. He has a 1993 chevy g 20 van, that when i give it throttle, the antilock brake light comes on and the van looses all power as if the antilock brakes are engaging. i pulled the rear drums off and found that the linings are down to metal. i have new chevy parts on order but was wondering if this could cause the brakes to engage. any thoughts and response would be a great help.
