Dana 60 Brake Shoe Question

[SavageC20]

I am replacing the brake shoes on a dana 60 axle out of a 1970 c20. The last guy that did the brakes had both primary shoes on one side and both secondaries on the other.

I got a new net of shoes from Napa but the friction material is the same length on both sides just positioned differently. I am not sure which one would be considered the primary shoe. Did they make these new shoes incorrectly?

I would put the higher liner to the back and the lower to the front.

I think the shoes grabs and sucks the shoe from the 6 - 8 o'clock position
in towards the drum

Probably wrong but if it doesn't work reverse it , sorry best guesses aren't
great

Another site I referenced says this"

You are correct, the shorter shoe should be forward on electric brake assemblies like the 12 inch Electric Brake Assembly, # 23-105, that your selected. In my experience, the shorter shoe is always the shoe that is pressed against the drum first, and the leverage from that connection is used the activate the longer shoe. brakes are engineered in this way to provide smooth braking performance.

Higher/longer liner towards rear. Lower/shorter liner towards front. First pic passenger side, second pic driver side on our '72 C20 with DANA 60. Hope it helps.

I would take them back and find a set of shoes with the proper length on the secondary shoe. The factory made them that way for a reason. The primary shoe forces all the mechanicals to rotate the shoes into the anchor bolt, which is a positive stop. The secondary shoe should be fully lined. Interestingly enough, when I bought my brake shoes from NAPA, all four shoes were fully lined like I expect the secondary shoes to be. Strange. I have a D60 in my '70 C20, as well.

I ran into the same problem last year.

As I explained in my post, every place I checked at the time had a variation of Napa's 419 part number.

I do have front disc brakes on my '67 and the short linings don't seem to represent a problem in normal driving.
One thing I noticed right away and the problem still persists is that the e-brake does not hold as well when parked on a hill. I have to apply the e-brake extra firm or it will roll back. Parking down-hill is OK.

Steevee keeps insisting his Napa brakes were full length. I suspect that when he bought his, the Napa store had old stock on its shelf.

Edit;
Peppertree, where did you get those shoes and how old are the pictures?
Those are the 2 1/2" x 12" shoes?

[Steeveedee]

FWIW those shoes I bought replaced shoes that were the same long length lining on both primary and secondary shoes, and I put those shoes on the truck when it belonged to my FiL, must be 25 years ago. Wrong then, wrong now, in my book. It should have been less lining on the front shoes.

Thank you for the pictures, these will help a lot. I am just going to use the shoes that I got and see how it works out.

My 68 has what I believe to be a Dana60 rear (photo below) and I was going to ask if there is a way to know if the shoes are 12x2 or 12x2.5 without opening things up. The more I read, the less it seems possible until you take it apart.
With that said, I am about to place an order from Rock Auto (screenshot below) and hope I ordered the right parts ; )

[DA71Grande]

These were the ones I got from Napa 12x2.5

[KevinK7]

Thanks for the NAPA # (FT419R), I may end up going that route, as I just found the Centric part (112.02480) is 11" x 2.75".

General question regarding 'diameter':
For the Dana60 rears, are drum brake pads all 12"?
Additionally, is there a 'set' width (on the Dana60)?

I see the NAPA part is 12x2.5

yet I am seeing widths anywhere from 2" - 2.75", some of which I am sure cover the HO52 rear.

[Steeveedee]

Mine are 12" X 2.5". I told them it was a Dana 60. It's cast on the punkin part of the housing on the top or passenger's side. It's been long enough that I don't remember which spot. NAPA makes a distinction about leaf springs, but there are obviously D60s with leaf springs!

The whole mention of "Leaf Springs" threw me off while ordering, since my '68 has coils. One would assume brake pads wouldn't differ between leaf vs. coil...

Mine is coil dana60 with 12” drums

[chevmn]

Here is the Part # I ordered yesterday..... ... Napa part UP UP419R shows for leaf spring truck, but mine is a coil spring '72 C20 with big block, but sure looked like that was the only way to order shoes for a Dana 60 with 12" drums unless I missed something. I just also ordered a set of drums as well from NAPA. Will be interesting to see what I get, as these are relined and had a core charge on them. Hopefully I can return them to the local Napa store if these will not work for some reason. Only reason I am replacing drums and shoes is that it appears one shoe might have been somehow stuck, and not only wore out the shoe, it really hurt the drum on that side.

No but Yes is the answer in short. I had a set of those, they cracked I took them back for a full refund. The Primary is the one with the friction material mounted higher in position relative to the half round mount for the pin next to the wheel cylinder.

I bought some shoes from Advance which is their WearEver brand. They had more length in friction material on them. I have a Dana 60 with leaf springs and 12 inch drums.

Hope this helps.

Short complete answer is YES they do!

[chevmn]

Sounds like I might have yet another set of incorrect shoes on the way, but it appears (according to Napa) they do not stock correct shoes for a 72 C20 coil spring Dana 60?

Oreilly (not a fan), only lists one set of shoes for a 12 inch dia. drum, and no specifics with regard to spring type.

Autozone as well, lists one type for 12" dia drum, but specifies leaf spring axle.

Not ordering more from Rock Auto due to paying shipping both ways to return, and I already have a set I cannot use, which I ordered about a year ago (for C20 with coil springs, but obviously not for 12" dia drum)

does anyone carry the correct shoes for a Dana 60 coil spring truck? What is the difference between leaf and coil when it comes to backing plate, and mechanicals in the drum? Pretty sure that if the shoes I receive match what is coming off the truck I am going with them.

Here is what I bought for my Dana 60 3.54 with coils from Rock Auto.....

Bosch BS419R They fit good.

https://www.rockauto.com/en/catalog/...rake+shoe,1688

I would say that the UP419R would probably be correct. The UP part would just be a different manufacturer than the BS part.

I am going to post all of the part numbers in the thread about my Dana 60 install in my '68 C20 in a bit.

Thanks....makes me feel a little better since my truck has that same rear.....Dana 60 Powerloc with 3:54 gears (factory big block TH400 truck). Received new drums from NAPA which look identical to the drums that were on it and probably factory, but too far gone to reuse. Fingers crossed the shoes match what came off. Good info and thanks for posting part numbers for future and surely others will run into this, and there are several posts on the topic.

[KevinK7]

Ditto!
Leon, THANKS! for the part numbers, that's a huge help with this.
