Not sure which forum this should go in,, it's not armored,, perhaps it is some kind of a "Deuce Modification", so I picked this forum. Never seen anything like this, it appears to be an M35, with a halftrack mod in place of the rear axles. Anyway, I present this for your...

It's been a long time, but IIRC, the cupped washer went between the shoe and the backing plate, on the lower guide pin.

Also, you may want to check in the -20, concerning the return spring placement. I believe that both ends of the return spring are to be hooked into the elongated slot that the anchor pins ride-in. In your #1 picture, the left-hand of the spring is in a hole above the slot, this makes the spring...

Excellent post Brian. The old-fashioned quench area/volume/shape of the engine does'nt really lend it self to the efficient use of fuel, to make horsepower, as you quickly run out of the ability to remove excess heat. In this respect, it's kind like a Flathead Ford, only with over head valves...

You'r right, it's the slotted piston version, sorry about that. There is/was a normal piston version, but I can't remember where I saw it.

Don't hold me to this, but I believe that for the 1.5in WC, these are the part #s. Raybestos WC 4511 Napa UP 4511 Dorman W 4511 Sorry, do not have the rebuild kit #s.

Because the radius is squared for area, it does'nt take much diameter increase to add more force, a 1.5in WC will have almost a 19% increase in the pressure, that it applys to the shoe, for the same pedal pressure, compared to a 1.375 WC. But nothing is free, you need to move almost 19% more...

So much of this process of installing an air operated duel curcuit brake system seems to be an excersize in futility. This whole thing about custom made brackets, an expensive MC, another air tank, another airpak, more air lines, more plumbing, duplicating the later AF trucks, etc., is...

Those airpacks were built by several companys, like Parker-Hannifin/Bendix/Haldex, and several others. There are many companys that have huge warehouses full of just about anything that has a NSN. Places like this, just type-in a NSN, and see what you get...

Way at the bottom of the anouncment;" *The military product lines are not included in the sale represented by the M151, D198ER, D298ER and LDT engine lines".

We have to realize that one brake assembly, (two shoes, one drum), in a duece, has ~12kw of energy dissipation. That equals about 15 HP. That 15 HP. times six, = about 75 total HP. So, a deuce has about twice as much "go" power than it has "slow" power,,take it easy, it's a 65 year old design.

It comes down to the weight transfer loading, normal front/rear bias is ~60/40, and in a deuce, without a proportioning valve, and a single curcuit, the two unloaded rear axles, do not contribute nearly as much braking effort as the fronts.

Sure, looking at the weight data plate, you see that standing still, and unloaded, the front axle is carrying almost as much weight as both of the rear axles combined. Under hard braking, without any load in the back, the two front brakes are doing at least ~60% of the total effort, with only...

Energy goes up as the square of the velocity. If those trucks were/are driven at the slow speeds the military envisioned, with a few tons of weight in the back, the brake wear becomes much more even front to back.

TNJ Murray has both the short, and long rebuild kits, their part #, for the short kit is RN-25T.

A small, but perhaps usefull point. The wheel cylinder rebuild kits that are being supplied by Big Mikes, and Eriks, and some other suppliers do not come with cup expanders, or the "shouldered spring". They come with a straight spring only. The original military cylinders, and rebuild kits had a...

Something else to add. Here is a link to an outfit that can supply all kinds of stuff, or at least provide info about various NSN items. This link is for the driveline bolts, NSN# 5306-00-752-1001 http://www.iso-parts.com/NSN/5306-00-752-1001

When you put things back together, you should use new nuts, this is the proper one. It is a one-time use item, but will not allow vibration to loosen the bolts. http://www.fastenal.com/web/products/details/38084? If the link does'nt work, it's Fastenal part #38084

I'am pretty much a newb here too, but I spent most of my time in the Army wrenching on, and driving deuces. The first three most important things on any of M35 series is; Brakes, Brakes, and more Brakes. No one year is much, if any, better than another, although the early 427s had a problem with...

I know that this thread is ~3 months old, but I thought I might add a bit to it. Since coming-on-board, I've been reading thru previous posts, going back,(so far), ~220 pages, taking/making note of everything concerning M35A2 brakes. It seems that some of the wheel cyclinder rebuild kits have...
