The Stovebolt Site Forums The Parking Lot Big Bolts 1951 chevy 1.5 ton Brakes

I've seen some pretty extreme rods that started out as real trucks. I understood you weren't headed that way.

Grigg's suggestion of converting to 12 volts is a good one. I just assumed the brake controller and didn't stop to think your truck is probably still 6 volt. I worry about trailer brakes failing and like my trucks big enough to stop the trailer without the trailer brakes if needed.

Its unlikely you'll find a dual master that can be mounted the same way the stock master is. The usual approach is to buy or make a bracket that mounts a modern dual master. Most the old truck vendors carry one and last time I bought it was less than $100.

Then of course you still need an appropriate booster and master cylinder. I'm thinking the best answer might be something off a '68 to '70 (first years with dual master but before disk brakes) Chevy or GMC bigger than a C-30 but someone else may jump in with more knowledge or a better idea.
