OldIHC

Somehow after my teardown about eight years ago, I misplaced (threw away?) my hand brake cables. My Truck is a 1951 L-110 with the lever attached on the left side under the dash. I was going to take the old ones in to a cable shop and have them made, but now I don't know the lengths. Does anyone have a part number, or lengths and connections needed? Perhaps an old set for pictures and measurements?

thanks

If your truck has the rear wheel e-brake, there are different length cables based on the wheelbase of your truck. From the MT-63 parts book, for the 115" wheelbase [short bed], the rear cables are the same left and right, part number 83 573 R91. For the 127-inch wheelbase [long bed], the rear cables are also the same part numbers left and right. part number 83 592 R91.

The front cable, from the control to the cross shaft, is part number 83 567 R92 [unless your truck is right-hand drive; that one is 83 746 R92].

I don't have measurements on them--and at near zero, I'm not going to go crawl under the truck. Hopefully, somebody may be able to cross those part numbers over for you.

If his truck is like mine he has the brake drum assembly around the drive shaft, I dont know what length i need to rebuild it and just havent gotten around to it yet

As mentioned you could have an emergency brake on the rear of the transmission or using the rear wheels. I think the tranny brake has the center floor park brake lever and the one using the rear wheels uses a brake lever along the left kick panel by the drivers feet. MM

My '52 has the driveshaft drum and band, but it has the lever under the dash. Sounds like a Rube Goldberg setup to me. That's why I have a K-series floor lever for my build. [Besides, IMHO the L-series floor lever looks more like it belongs on a manure spreader than in a truck to me...but I grew up in an IH farm equipment shop.]

Thats what i have the left side lever ith the driveshaft band

My 1950 L112 has the brake cable to each rear wheel, coming off of a rotating shaft that is under the cab frame.

So what determined whether they used the drive shaft brake mechanism or the rear brake shoes in these trucks?

The MT-63 parts book says the rear wheel parking brake is used on L-110/111/112 below chassis number 37714, and L-120/121/122 below chassis number 16385. And the driveshaft parking brake is used on L-110/111/112 from chassis number 37714 up, and L-120/121/122 from chassis number 16385 up.

HE SAID: but I grew up in an IH farm equipment shop
I have a cousin with the same childhood situation. It scarred him for life. After graduating from trade school he got a job at another implement dealer and he refused to go home at night. When they opened the shop in the morning they often found him sleeping in a manure spreader with his" parking brake lever" firmly held in both hands. It was around that time that his wife, the former parts department manager, insisted that he stay at the dealer at night because he didn't smell great. His name is Trevor but we all call him TURD
I suppose that a driveline brake is only as secure as the strongest part. I am thinking that if a sketchy U joint lets go, on a hill, it would only stop in the morning news.
One of our New Canadian Neighbours was doing something under his Econoline Van. It was facing down hill and the wheels were not blocked. When I returned from NAPA, there was an ambulance and tow-truck at the scene. The neighbour had been loosening the "U: bolts on the rear universal joint and at some point the Econoline took off, down hill. It stopped in the newly planted bushes of a renovated house. After rolling Mr. Fix-it for a short distance he was left laying on the street, while the van continued on for a block. He was patched up at the scene and his Econoline was pulled from the Cedar bushes. Another neighbour was mowing his lawn as the unmanned van passed where he was mowing. He said the driveshaft was dragging and the van was going about 40kmh+ and in a few seconds a short limping man came by, Vise Grip in hand, with his voice raised in confusion and anger.

The reason behind the driveshaft brake is that it turns 3-5 times faster then the wheels, and the torque is 1/3rd to 1/5th the torque on the wheel. It is easyer and stronger to apply the brakeing force to the driveline over the wheel, the drawback is Nikki's story!
