The Stovebolt Site Forums The Parking Lot Big Bolts 1960 GMC V4000 help

Hi folks. My newly acquired truck used to have a dump bed but that's gone on a different journey. Brakes are my big issue, as in I have no brakes. I've got a steep learning curve on these brakes, they look to be manual but if I understand the vin correctly supposed to be vacuum assisted. Just getting started on a very interesting trip. Any help is appreciated, thanks. Denny
