In your picture of the parking brake spring and rod, how long is the wire hook between the spring and the clevice? Mine was missing the wire hook, but I have the rod and the spring is still attached to the frame. I grew up not to far you, (get this, the towns name was "Bulpitt, Illinois"). It was a coal mine town about 30 miles south of Springfield, population 250. | | | | | Joined: Sep 2006 Posts: 47 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2006 Posts: 47 | Denny, great pics and explanation..you should rewrite the factory manual! | | | | | Joined: Jul 2006 Posts: 482 Shop Shark | | Shop Shark Joined: Jul 2006 Posts: 482 | Nice gallery. It looks like you are doing a masterful job of restoration. It looks like you share the same rear end as my '57 3600 but the brakes are slightly different. Just curious what you will be doing with the front brakes. Insofar as discs must be engineered for these things, I installed a hydrovac and kept my drums for the time being. Be interested in your opinions and comments, Thanks, Skip | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | Denny, very nice photos, before and after and that tool. It looks like you have overload springs and I thought they only came with the trucks 1 1/2 Tons and up. I wonder it there was some kind of option on the 3600. Mine is a 1 Ton single and there are no overloads. | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Eric, the wire is 7" long over all. The hooks are bent around a half inch dia form, the front one that is hooked into the clevis has about an inch of straight leg on it and is bent about 160 degrees. The rear hook that goes with the spring is bent a full 180 degrees and only about an 1/8" straight leg. The wire diameter mics at .112". These are available from vendors like Jim Carter, LNC, Chevy Duty and are relatively inexpensive. Skip, I'm trying to keep every thing stock. The front brakes are finished the same as the rear. I think the later brakes were Bendix as opposed to the Huck brakes on the '50. Fred, I’m not sure myself, the ’49 Truck Data Book shows option 267, Auxiliary Rear Springs, available for series 4000 but makes no mention of an option for the 3600 series. The standard spring according to the chart was a two-stage type and says the 5000, 6100 and 6400 came with the Auxiliary springs. The 3600 frame is 5 27/32” and the 4100 frame is 7”. These spring bumpers are bolted with a clamp to the inside of the frame and they it my frame width so there must have been an option for the 3600 series. Denny Graham Sandwich, IL
