Finding the "good" wheel cylinder kits...

[ckid]

Does anyone make the "good" wheel cylinder rebuild kits for the Deuce anymore? The ones with the cup expander springs? Even on the surplus sites, all I see are the straight springs. Did a search for UP45 through NAPA and it comes up with nothing.

What about the whole cylinders on the surplus sites? Anyone know which springs they have in them?

Rebuilding my entire brake system and would really like to NOT put in crappy straight springs.

Yep. Checked out Erik's before. He has this note in his description: Note- spring is no longer manufactured with tapered ends. You will need to reuse the original spring if the tapered end is required.

I've not torn mine open yet. Hope they haven't been rebuilt in the past with straight springs if nobody is making the tapered anymore.

Last year when i rebuilt / replaced mine i searched for a while to find the good ones but to no avail. I called napa and none of the numbers that have been used in the past worked anymore or they couldn't get them anymore. called several truck parts stores around locally but nothing. I wound up getting the other straight type through big mikes. so far so good though. none of my originals had the expanding cups on the springs so reusing the old ones wasn't a option either.

I have everything but the piston part. I have body, rubber, springs, some the tapered kind and some straight.

You know why the straight ones fail don't you? It's because they try and use them with no steel cup on the end, and instead put the spring directly against the rubber. The new style spring has the end so it distributes the force but is still wire against rubber. If the straight spring has the end cups, in my opinion they are every bit as reliable as the new style.

Thanks for that tidbit @tobyS . I hadn't even thought about that, but it's a good point.

 

[tobyS]

If I can find them I'll sell it all (6). I'm using 1.5" on my 4x4.

Edit....I think I traded them...sorry

Put in "1 3/8" wheel cylinder kit " into a Google search

REPAIR KIT, WHEEL CYLINDER - #F-2128-5 - National Parts Depot (npdlink.com)

Dang, @jasonjc , you da man Thanks.

 

[GopherHill]

It's really worth your time to hunt down kits with the sheet metal cup that fits on the spring end. Wheel cylinders are much less leak prone with them. Try small independent auto parts places for some new old stock.

Dang, @jasonjc , you da man Thanks.

Just did what @tobyS said to do

Will Napa part UP 21 or UP 127 work?

 

[tobyS]

Will Napa part UP 21 or UP 127 work?

The 21 will work if you have 1" piston and the 127 will work if you have 3/4" pistons. So in relation to a deuce....NO

Rather than start another thread I'm kicking this one back up. As noted in much earlier threads the Napa UP 45 kit is long gone. I checked on the Napa UP 4419 wheel cylinders and I can only find 6 of the complete wheel cylinders in the entire PNW Napa supply chain. 4 of which are right here in town.

Using the link from an earlier post I ordered seven F-2128-5 kits from National Parts Depot. What I received was a hodge-podge. These were supposed to be Wagner kits as confirmed by their parts manager. I received 4 Raybestos WK103 kits and 3 generic Made in China kits with just a piece of paper inside with WK103 printed on it.

The Raybestos kits have Made in Mexico labels but came with Made in the USA cups. The generic kits came with unmarked cups. All seven kits have the good springs. I'll keep the springs and end caps from the generic kits and try to locate six USA manufactured cups to compete these kits and keep them for spares.

I now have one of the Dorman 3577 kits coming in for inspection. If the Dorman kits are of good quality they should be a viable option. They cost less and include the pistons. Fingers crossed. I'll report back when the Dorman kit arrives.

The "handwriting" is on the wall guys. These old drum brake vehicles will not be supported much longer. On any old vehicle. Every new vehicle made now has disc brakes. Much cheaper to make, and less warranty problems for the manufacturer. Even in the old car world it is becoming harder to find good brake parts. Unless you own a classic that everyone seems to have. Then some "specialty shops" will make replacements parts at a huge mark-up price. Since our military vehicles are in a really small niche market, no one is going to invest the money to make small runs of simple parts like brake cups. So find some parts now and stash them away. That includes "booster" parts too.
Soon the only viable option will be a complete conversion to disc brakes.

The air packs are my next concern. I'd like to have a couple (NOS or used) on the shelf along with a couple of rebuild kits. Right now I'm spending far more time tracking down spare parts to put on the shelf than I am actually working on the truck. Sad state of affairs.

I do hate to hear that. I'm sure you are
correct but I like drum brakes.

Yes. I know that feeling well !
