I have a 45 2 ton Chevy I did a complete brake job a few years back, all new hydraulic parts,hoses,master and wheel cylinders,brakes relined at a local shop, the drums were just fine,cost about 300 bucks for the parts. Make sure you check out the axle bearings carefully.
Our 45 truck has no Hydrovac, it stops just fine. My wife drives it around town with no problem, if you intend to carry heavy loads, a vacuum assist is nice.
