My rear drums and brakes are currently ok, but I've been preparing for when they may need to be addressed.
According to this tech article: https://www.stovebolt.com/techtips/axles/1%20Ton%20Upgrade/
the authors mention:
All HO52/72 rears can use any year of brakes. So a dual rear wheel rear brake system from 72 bolts in place of a 47 DRW system. Plus, almost all 14 bolt from 73-2006 brake system will work also
. Wow, so you can ditch those Huck brakes at the same time ...
I have a dually with the HO72. If I'm reading this correctly, does that mean I can have a modern set of of rear drums if I can source all the parts from a 90's 3/4 or 1 Ton?
When I got new 19.5" rims, I had clearance issues with my stock rear drums, so I started playing around with this. The 90's dually drums are way too wide. They fit the on the hub perfectly and clear the rim, but extend way back almost to reach the leaf springs.
The backing plate also fits perfectly. I tried using a single wheel drum, but it didn't clear the rim, so I didn't pursue checking axle clearance. I ended up using a wheel spacer to make the rims clear the original drum.
I'm thinking about experimenting with this again. It would be nice to have rear brakes that use parts that are more plentiful.
Before I embark on finding parts and stuff, has anyone done this? Can you just bolt up a full set of rear drums from a 14bolt on an HO72? Any tips?
Thanks in advance for the collective wisdom!
