I got the other two for cheap, they were “add on” orders only. I had to spend 25 bucks on other things before it would let me add them to my cart

Are the WC28851's the only wheel cylinders available (that are factory fit)?

Federal Stock Number Supplier indicates that all the parts numbers listed (includes WC28851) are EQUIVALENT Parts.
https://www.wbparts.com/rfq/2530-00-678-5122.html
2530-00-678-5122 is the Federal Stock Number for the WC28851 Wheel Cylinder, and Ford B8T2262A.
You can't buy from this Federal Supplier . . . but all the listed Part Numbers are good for Google Search.

Update . . .
This afternoon I have checked the following FMC Wheel Cylinder Part Numbers and are all AVAILABLE.
There may be other FMC WCs out there with still different Part Numbers. Search away and please share the POSITIVE RESULTS you discover.

FMC Drum Brake Wheel Cylinder (you need 8 each) Part Number WC28851, or 134.82004, or B8T2262A, or UP28851 at NAPA. All these #s have 3 ports . . . two outside and one inside for the transfer tube.

OR you can get 4 ea of the ABOVE Part Numbers to use in the LOWER position . . .
and get 4 each of Part Number W28860, or W37151, or 134.79091 for use in the UPPER position. All of these second group of #s have 2 ports . . . one on the outside for a bleeder, and one on the inside for the transfer tube from the LOWER wheel cylinder inside transfer port.

They are DRYING UP and might disappear altogether this year. When they are gone . . . there GONE !
Currently between $34 and $65 each, plus shipping (if any).
You could have your WCs stainless steel sleeved but it would be VERY EXPENSIVE, and is not always done well.
The WC rebuild kit is Part Number WK195.

If you want to "SAVE" your new wheel cylinders for as long as you own your FMC and never have to mess with them again . . . CHANGE TO DOT 5 BRAKE FLUID.
PITA . . . but worth it !!!
Now . . . BRAKE ON and ON and ON ! Lou #120

More good stuff - thanks Lou!

Once again, this underscores the need for a workable disc-brake solution for FMC owners.

Yes, there's the bolt-on MCC (Barth) set up out there if you can find one that's being parted out; however, they only built something like 43 of those coaches. I count myself lucky to have gotten' a set when buddy Jay parted his out a few months back.

I'm going to discuss this further with Jay as he'd spent considerable time trying to source parts for the brakes on his MCC a few years back. He's a very smart guy and knows a lot.

When I was down in Arlington, Wa. getting the wheels and brake parts etc off his coach, he said something that stuck with me.

He said he was certain that the calipers on the MCC (same as the FMC transit set up) were off an early 70's GM 1-ton truck. 74' I think. He also gave me a bunch of paperwork (files, receipts and handwritten notes) that he'd accumulated during the years he owned his FMC.
I'll go through all that stuff again, too, and see what if any references there are in there to brake parts.

It would seem that if there is in fact a GM truck caliper in this configuration, then it follows there could also be a rotor as well.

If there are other brake parts out there that could be installed on or adapted to our coaches - it's high-time we figure that out.

the rotors and calipers are probably the easier part of the disc brake puzzle, it will be the caliper mounts that really determine how doable the project is, if they are custom fabricated then they would have to be reverse engineered for new fabrication. Some detailed pictures of these parts would help.

The carquest number does match up.
The disc brake discussion will interesting. The pads are #149 Wagner and match up with the Chevy caliper. I have one new adapter, one caliper and a few dust/rock shields. No rotor.

Agreed, it would be and interesting discussion. Maybe a new thread. Would also get Borrmann in on it as he's also look hard at this, if memory serves.

Where's Randy Bradshaw? Let's go all out on this one!

When I get a chance I'll dig out the caliper mounts and post some pics. Don't recall but I think both front & rear were identical. Cast iron I think.

Got all the brake parts tucked away for next years project after the engine and trans is done.

BTW: I was perusing through the FMC site the other day and stumbled upon some transit new-rotor thickness specs (thanks Kjetil!). Says the new rotors on the FMC transit were - 1.43" thick.

This caused a sigh of relief with me as I recalled measuring mine and they were all over 1.4".

Here's a few pics of one of the caliper mounts used on the FMC Transit & MCC (Barth).
Not positive on the part # I took a pic of. If it goes no where I could cross reference some of the other mounts I have to confirm.

There's 6-pics altogether in the Album starting with this: http://www.fmcowners.com/mbbs22/photos/show-album.asp?albumid=145&p...

On the FMC site under 'Publications' you'll see Transit Coach Specifications.

In section on 'Brakes' it says they are 13.07" dia rotors while the calipers have 3.38" dia pistons in them.

Haven't measured my rotors but I'm assuming they are the same diameter; however, I'm going to whip out and measure them now as mine are 6-bolt wheels and the Transit's were all 5-bolt. Now I'm curious.

Okay, I measured'em and they're the 13" dia rotors but the bolt circle is more like 8 3/4" vs the FMC's 8" bolt circle. They're also 6-lugs at 3/4" dia ea.

Something fishy is going on around here?

I think maybe you nailed this Lenny. Too bad there's no dimensions on it.

Now, if a guy could source rotors for these we'd really be getting somewhere?

Rotor's I've had time to look at (1977- up) that appear to work with the above listed caliper mount, all had 8 bolt wheels and I'm not getting any rotor specs. Have to run, maybe look at this later.

Hell, if the worst of it was we had to switch to 8-bolt wheels in order to swap to a good disc-brake kit we'd be laughing.

that was a fat finger on my part, I meant to type 13", that's also standard diameter(actually dimensions range from 12.5 to 13.1 I think) for the Dana 60 front axle. if you get a chance to post some pics of the rotors that will help too..

looks like a pretty typical DRW rotor configuration, the funky wheel/lug pattern is probably all that really sets it apart...the caliper mount bracket is really the problem, it appears to be much thicker than the Dodge/GM truck versions and in the end you are just getting an old school single piston caliper for your trouble. I'm going to dig into some of the dana60 "big brake kits" and see what is available to get to a modern caliper setup..

I guess its time that I joined in on this conversation since I own an FMC (#639) and an MCC which I purchased on ebay in Seattle 3 years ago. Jay Bergstrom and his wife hosted me and helped me prepare for the trip back to PA. He also shared much of the knowledge that he had acquired while owning the MCC. I have a scored rotor on the MCC and have been casually looking at trucks in salvage yards to see if anything matches but have not found anything. I will include any info that I discover. Also, I would like to pose a question to Bill Sitton who I believe is in possession of the parts from RVS. Are there any wide windshield rubber seals among the parts that you have? I will eventually have to replace my passenger side windshield. Any help would be appreciated. Thanks, Bob

Welcome Bob!

Jay spoke very highly of the time he spent with you. I count myself lucky to know him and his wife as friends. Quality people through and through.

Do you live in the same neck of the woods as his son?

I've kept in touch with Jay since he's sold his place. He tried to call me last weekend but I don't get cell service where I live so I missed the call. They're on the road, 'seeing America'.

Look forward to any/all of your input here.

Cheers,
Terry
