Default e-brake cable for HUP

I'm looking for replacement emergency brake cables for a HUP, the parts book number is 5805717. I would think from comparison they are the same as a C15 cwt. Does any one know of a currently available cable part number. My parts shop tells me they can have one made if I had a complete cable, which I don't. The Chevsofthefourties cables are not correct and don't have the anchor grove for the lock bolt.
Thanks

Gordon

I think the Ottawa guys traced a ford one from Macs Antique Auto parts store that works for the CMP.

Default Need the HUP guy....... Rob ??????

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!!!!

Bob

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.

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.

Default slight Korrecshun.......

......he means the E brake system attached to the transfer case.....

....easy bolt on transplant from C60 to HUP Transfer case.

Gordon intend to drive very fast and use the E brake for skidding U turns...... maybe running wiskey!!!!!!

Note....... some of the attachement bolts will need shimming with extra washers where the C60 cast yoke leaves a small space near the T case....... once filled with spacers/washers there is less change of over torquing and twisting/cracking the yoke.

Cheers

It's worth noting that Bob's C15A had seen use as a tow truck in a previous life and as a result had been retrofitted with a complete two speed transfer case with winch and had both the driveline and wheel emergency brake setups in place when Bob got it. I mention this as it could raise doubt about whether any old C15A transfer case can be retrofitted with the driveline emergency brake.

Comparing the C8A and C15A parts books shows 5 different part numbers for C8A transfer case assemblies. The first 3 are common to the C15A (which only lists 3 different assemblies) so I think it is fair to assume that the single speed case assemblies used on C15A and C8A with rear wheel emergency brakes are interchangeable. I have retrofitted a driveline emergency brake to the single speed transfer case on my C15A without any significant difficulty. I think that all single speed cases can be fitted with the driveline brake as the C8A parts book only gives one set of part numbers for the transfer case housing, regardless of the brake setup used. The only minor issue was that I found very little clearance for the actuating rod, but it does work. Bob is correct that the "Bracket, Propeller Shaft Emergency Brake Anchor" does require shimming as it is attached to the transfer case. The shims are factory parts, coming in 0.003, 0.005 and 0.010 inch thicknesses. Standard shim stock is just fine - no need to find multiple cases to rob for factory shims. The shimming procedure is in the maintenance manual.

Bob and Grant

Thank you for all your tips, advice and help. I'm sure that I will need come coaching as the process gets started. Contrary to Bob's suggestion of whiskey running, I plan on less dangerous road use and just want a dependable e-brake system.

Default How about this cut to fit cables

Hi Guys

Just found this while looking for something else
Quote:
Lokar U-Cut-to-Fit Rear Brake Cable Kit for 1942-54 Chevy Trucks
Brake Cable Kits for 1942 to 1954 Chevy Trucks. Cables mount from backing plates on rear end to original cross shaft on chassis. Designed with specially extruded liner for extended life of the cable. Stainless inner cable resists moisture. Kit includes two 4-foot outer housings that ''U-Cut-to-Fit'' and are available in stainless housing or black housing. Design allows rear end backing plate fittings to be removed without removing brake cables. Lokar cables also feature two adjustable cable locks and clevis. Application fits 8-inch and 9-inch Ford, Chevy, Chrysler, and Lincoln Versailles drum and disc brakes. Also fits 1987 and earlier Corvette rears. For 1988 or later Corvette and Wilwood disc brakes (with separate e-brake caliper), cables require Wilwood Clevis Kit (sold separately).
