I'm looking at trying to figure out as much info on 55-66 chevy gmc semi trucks and their brakes. any info is much appreciated. I would like to find one of these truck to use to haul grain. i don't have a long haul and i think it would be pretty neat. I would try and get an older grain trailer, so can you do something like that with air over vacuum brakes? or do you need a full air brake system? how does it all work? i just am not sure the oldest semi i've drove is 94 w900 thanks mike
