The Stovebolt Site Forums The Shop Area Driveline 46 disc brake conversion question

I want to convert to disc brakes on my 46 1/2 ton. Any suggestions on a master cylinder and how to mount it or, a kit? Im not having much luck finding info on 46 and older trucks.

I cannot answer you question, but some of the best places to check out information/parts are:
Chevy of the 40's website
Jim Carter Trucks website....Jim Carter is the best information available when you call them...

Mine came with brakes already converted. I HATE the place they put the vacuum canister and master cylinder, which is conventional, left, upper firewall. Although much harder to maintain, I would have much preferred both mounted to the frame below the cab. Plenty of kits for that from sources above.

You'll be doing some fabrication no matter what so be ready for that.

You can mount a new master cylinder and power brake booster on a beefed up fire wall using a steel back up plate and replumb the brake lines to give you a safe split system.

OR

If you prefer a more original looking unit you can look for and obtain a 40 to 46 1 ton and up 4 speed system consisting of a rod from the brake pedadel back to a bell crank located on the frame and then forward again to a 2 chamber master cylinder for a split system. Do not bother with a power brake booster here it is too hard to fit in the system.

I took the 4 speed brake components off my 41 1 ton and transferred them to my 1946 Suburban for a stock look using a 235 motor.

I mounted a new brake booster and master cylinder on my 1 ton on the fire wall because with a SB350 and 700 R4 transmission there was no enough room left to mount it all on the frame of my 41 ton. FYI, I used a dual chamber brake booster.

I purchased my disc brake kits from Jim Carter and my power brake kits from Pirate Jack.

Thanks for the information guys. The best part about owning an old truck is working on it.
