9" brake upgrade

I really don't care for the stock 9" brake setup, the way the drums are removed in particular. I want to kep the '49 stock, but make it more user friendly. I had some axles from a junk 3B that have drums that fit over the hubs. Nice easy mod to do and now they are a lot easier to work on now.

 

The late 9" Bendix Jeep brakes (1953-1971) were improved as compared to the early 9" Jeep Bendix brakes ! (1941 -1953)
The early 9" Bendix brakes require 4 eccentic adjustments per wheel while the late Bendix brakes only require 2 eccentric adjustments per wheel.
With all drum type brake systems the drums must be removed to access the brake shoes.
With the early Bendix system the hubs must also be removed to access the brake shoes.
With the late Bendix system one can access the shoes without hub removal.
The early drums were swaged to the hubs via serreted lug studs while the late drums are loose after the 3 retainer screws are removed.

No need to have a swage cutter for M38A-1, CJ-3B, CJ-5, CJ-6. DJ-3.

 

Yes, I was looking at the two types. It looks like I can still remove the shoes without pulling the hub off. I haven't had to replace 9" shoes yet since my other jeeps are upgraded..

The later 9" brakes (sixtys CJ5 style) use a bendix action rather than the fixed pivot Lockeed action that the earlier (CJ2A style) 9" brakes used. The earlier brakes can be Id'd by looking for the fixed pivot point on the lower end of each shoe rather than the later style with the movable lower star wheel adjuster as was common on most later model drum brakes. The Bendix action brakes multiply your foot pressure and work a whole lot better with much less pedal pressure required as compared to the older Lockheed style.

Many years ago I changed the early 9" CJ2A brakes with the 9" brakes from a mid-sixtys CJ5. It was a straight bolt on change. Besides the drum advantage for service as was mentioned earlier, The braking action and operation was also vastly improved.
