Three hard to find brochures for B. F. Goodrich Hi-Torque Brakes. The first one claims you can "stop on a dime" with Hi-Torque Brakes, and there is a real 1964 silver dime where the word dime would be! It is a ten page booklet. The second reddish one is a fold-out and talks about high profit features & competitive tests. The last one is a four page booklet, it shows many different vehicles such as the front shovel loader, mine shuttle car, and the straddle buggy as well as cut-away sections of the Hi-Torque brake. Great condition. Handwritten date on two covers.
