200 2wd front brakes, posible option?

[ruderunner]

So I know that the rotors for 2wd 200 are the hens teeth. Last weekend I went to a local wrecking yard and found 3 200 2wd SRW pickemups. 2 still had rotors and one had already had em scapped. If the weather cooperates I may get down there again to take a closer look at what else is left of the trucks and maybe grab a rotor and spindle.

At least I'll take a close look at the spindles on the truck thats missing it's rotors cuz I got a hunch there may be a simple spindle conversion that will make rotors cheap and easy. Think Dodge parts...

If I get a rotor to measure I'll see if anything is close. But I need some info from you guys. Mainly how many different rotors were availible on 200 2wd and what are the nominal specs for diameter and thickness and what are machine to and discard numbers.

I know folks have been trying to figure a way to get rotors for these things for years and the big stumbling block is the inner bearing. But there are ways to wrok around that (machine the rotor for a different bearing or sleeve te spindle or)

This is how I solved the problem. Takes a bit of machine work but once that's done you can use Dodge W250 4x4 rotors right out of the box.
These rotors have exactly the same dimensions as the OEM ones. No bearing problems since you'll be using the original hub as a carrier.

While that is a solution, it is still too much work in my eyes.

There has to be some sort of rotor out there that a simple bearing change will bring about a bolt-on solution.

Machine shops that are smart enough to do that kind of work are getting rarer and rarer.

Fortunately I can have the machine work done at my job so for me that's not the problem.
A bolt on swap would offcourse be nicer but the problem is that you need a combination of parameters to make it fit. Rotor diameter, thickness, rotor offset, bearing spacing , bearing sizes and lug pattern, they all have to be right in one part. And on top of that it has to be easy to get and preferably cheap.
Before I did my rotor modification I started with a scrap Dodge D200 rotor/hub for measurement. The rotor diameter and thickness of that one were a perfect fit, but most other parameters didn't match so it lead me nowhere in the end.

Thats why I'm thinking of a spindle swap. Preliminary checking shows that 2wd Dodge truck with the 4000# front suspension use the same uper ball joint and caliper. Since on the Dodge trucks the lower ball joint and outter tie rod do not attach directly to the spindle that may allow some swapability. I didn't look close enough at the 200 to see how the spindle connects to the lower ball joint. And theres nothing saying that the Dodge parts won't fit the 200 lower ball joint.

At this point it's all pure speculation, haven't looked close enough at an IH but I am pretty familiar with the Dodge setup.

Paul, exactly which Dodge rotor did you use? There are a couple listed for the Dodge w250 depending on axle rating. Whats the O.D.? 11.75" or just over 12"? It looks like the bigger caliper so I'm guessing the bigger rotor.

As stated before other options are a sleeve on the spindle to bring it's diameter up to the next common bearing size. It appears that most domestics use the same outter bearing as IH and that IH uses an odd inner while the others use either set 35 or set 50. Offhand I can't recall which had the larger I.D. but both have the same O.D.

Any pics of a bare spindle attached to the truck to save me from crawling in mud?

The 2WD version of this has been done by Paul B. in Belgium
I've replaced my original master cylinder with one from a Chevy 1T. I had to adapt the lines. the Chevy unit is readily available when I need one, though it's a 1 5/16" bore and intended for hydroboost, so I no longer send my passengers through the windshield when I hit the brakes - it takes more foot power, but stops just as well, just not as suddenly and unexpectedly
I used mid eighties W250 4WD rotors on my truck. But that's a 2WD 200 with IFS.
I had to make a 1/4" shim to get the same offset.
The diameter and thickness of these rotors is identical to the originals and with my modification I can use the Dodge rotors without any machining. Paul

So how much machining are we talking to make them fit? And just to make sure I'm understanding this, the Dodge 1-ton SRW 4x4 front rotors will work on a IH 74-75 200 4x4 with a little machining?

[Doc Stewart]

The information is just accumulated preparing for the time when my supply of spares runs out. I have not fiddled with any of these so I have no detailed response for you.

From what I remember you just have to increase the ID of the hole for the hub. I personally think that is what some of the vendors are doing.

[ruderunner]

I know that some vendors are selling rotors for 4wd 200 and that they are most likely a remachined Dodge 2wd rotor but wether its a hubless rotor to start or they are machining out the hub isn't clear. Dodge 2wd rotors were availible both ways.

Either way noone makes 2wd 200 rotors, yet. And they are a one piece hub and rotor assembly completely different from 4wd rotors.

At one point I had tossed out the idea that 8 lug Ibeam hubs may fit the 200 2wd spindle which may allow the use of the 200 4wd rotors. Kind of like what Paul did, just less machining. Reasearch shows they use the same bearings. Any takers on a mock up?

Either way I'm looking for a cost effective way to get some rotors for these things. Let's face it there are no new ones and good used are scarce too.
