e-brake cable for HUP

[Bob Carriere]

Hi Gordon

I believe they are the same as the C15cwt but need to check the parts manual and pick Rob's memory....... but speaking of memory....did I not trade or sell you a set I had from Mac that I no longer needed......

In any event will look up the info for you.

Stay warm and don't kill yourself shoveling!!!!

Based on the part number 5805717, you are working on a HUP with rear wheel parking brakes rather than the transfer case version...
That part number seems to be unique to the C8A. It doesn't appear in the listings I have for C8, C15, C15A, C30, CGT, Fox, Otter, C15TA or any of the 60cwts. I don't know about the C8AX (but my impression is that in very simplified terms it is a C15 cab on a C8A chassis). Even more awkward, it has the "*" = "peculiar to Canadian Military Pattern" in the column ahead of the part number in the parts list C8A-04.
I assume you've already checked with Brian Asbury, I'm sure he has parts that aren't on his list.

Check with Brian Asbury? Gosh could it be that simple!! I'll contact him.

Here are some pictures of my handbrake cables on my C15a.

After talking with Gord via phone they appear to be the same setup as used in a C8a.

WRT Brian - no guarantee but it can't hurt to ask..

The levers 596973 and 596974 that the cables attach to inside the drum are standard Chevrolet parts (the numbers weren't deleted from the GM catalog until about 1979) so if we can find what else the levers were used for that might be a source for "close enough" cables. A GM Parts Wiki search says the levers (left and right) were 1937-1952 1 Ton models JE, KE, AM and BM. Also 1937-42 Models GE HE KF AN and BN plus DS and ES.
These models translate as (source: Chevs of the 40s catalog):
GE 1937 122-1/4" WB 1 Ton Truck
HE 1938 122-1/4" WB 1 Ton Truck
JE 1939 122-3/4" WB 1 Ton Truck
KE 1940 122-3/4" WB 3/4 Ton Truck
AM 1941 125-1/4" WB 3/4 Ton Truck
AN 1941 134-1/2" WB 1 Ton Truck
BM 1941 125-1/4" WB 3/4 Ton Truck
BN 1941 134-1/2" WB 1 Ton Truck
DS 1946 134-1/2" WB 1 Ton Truck
ES 1947 137" WB 1 Ton Truck
Many of the listings mention 14" brake drums.
I suspect there were other uses in addition to the above given the 1937-1952 mentioned in one listing, guessing in the 3/4 to 1 ton range.
Of course, this only gets us the attachment to the lever inside the drum. It doesn't ensure the anchorage to the drum, cable length, attachment at the forward end to frame and actuating mechanism will match...
Levers 596973 and 596974 were C8, C8a, and C15. Not C15A or any of the heavier CMP as far as I can tell. From the outside the cable may look the same but there has to be something different about the attachment to the lever. Diagram from the parts list attached.

C8AX = an 8cwt Chev GS (4x4, 13 cab) assembled in New Zealand. The X being G.M's code for the New Zealand G.M plant.
These used G.M brakes while everything bigger (C15, F15, and up) used Ford brakes.

Thanks for all the info and responses guys. Bob Carriere has used the e-brake drum off the differential on his 15cwt and suggested I do the same. The C60 and HUP parts book have the same set up and part numbers for the drum e-brake. I have parts C60 with the assembly and will use it on the HUP. A far more effective e-brake and I have one at hand.
