Can anyone identify these Heavy Duty brake sho

Dave..they are 2 3/4" wide.

I wonder if any of the members have old Delco Morraine brake part manuals?

I am told that Morraine was making prototype HD brake shoes for the Corvette factory team in 56/57 and sending them straight to the teams.

Have also been advised that Bendix was another supplier.

Yes, Joe and I think some of that info is in Work Order 17792 which you reviewed at my house.

Re: Can anyone identify these Heavy Duty brake sho

The part #'s on the brake shoes are probably Delco Morraine #'s. I wonder if they can be cross referenced to the GM HD brake #'s.

I am told that each part used on the factory team cars..were required to have a GM part # issued..even the Sun Tach.

So I would guess these Morraine part #'s would as well.

Art..is there still a contact at Morraine in Dayton that you know of or do you or one of your local car members have any old Morraine parts books?

I misunderstood you when we corresponded about this earlier. I thought that the part numbers were numbers on a BOX that the brake shoes came in. However, if I am now understanding you correctly, the numbers are actually stamped on the brake shoes, themselves, and the 2 different numbers are not for front and rear AXLE wheel sets, but for each of the 2 shoe configurations.

In that case, the part numbers are internal Delco-Moraine numbers. They will not likely appear in any Delco brake parts catalog unless the catalog shows the individual part numbers for the shoes that make up one wheel unit. Gneerally, such part numbers are not provided. Individual shoes were never an item SERVICED by either Delco or GM.

Undoubtedly, these numbers are somewhere referenced in some GM publication or documents. However, it's probably not going to be as simple as finding an old Delco brake parts catalog. More likely, the publication will be an internal GM publication or other obscure document.

One possibility, though, would be someone having a known original set of the 57-60 or 61-62 HD front brake shoes. These numbers may be found stamped on them. If so, then you know what they are.

Yes..these #'s I detailed are stamped into the back of the brake shoe. I believe these are fronts.

I don't know if they are morraine official part #'s that would be found in a Morraine service book, or GM part#'s or otherwise.

See location of the # in the picture below.

Since a set of two for one wheel would have one part # as a service assembly ( I guess ) then these #'s may not tell me what I am looking for.

If anyone has a contact for old Morraine information..I would be grateful...as I also need to find out more about their participation in the 56/57 Corvette racing program.

Re: Can anyone identify these Heavy Duty brake sho

don't lknow if this'll help joe with the 57 hd brake car but i have here in front of me a NOS set of front and rears for the 63 ZO6. i advised the guy i bought the car from to buy the extra shoes from chevy when he bought the 63 ZO6 in '69 or 70. the shoes in front of me are the set he bought over the chevy counter in 1970( date on postage sticker on old gm cardboard boxes). anyway i pilled a rear shoe out the box and it is heavily stamped with 5464663, stamped delco moraine etc. plus there is an ink stamp which reads 5464718 PR also delco 105FF and delco 104EE are ink stamped(black ink) on the shoe. the front shoe in front of me is simple deeply stamped 5464662 with the delco moraine logo also deeply stamped in the shoe. it has no ink stamping. mike

Mike and Joe----

It is quite possible that the part numbers stamped on the metal portion of the shoes is the Delco-Moraine part number for that component of the shoe assembly only. If that's the case, it's possible that this component was used for more than one finished brake shoe assembly.

Re: Can anyone identify these Heavy Duty brake sho

I think all factory #687 HD front shoes for 59/62 were 2 1/2" wide. I don't have my notes with me but the 57/58 #684 cars may have used narrowerer front shoes. From my research the blind rivets were used from 62 and newer. The earlier 59/61 shoes had exposed rivets on the drum face.

Re: Can anyone identify these Heavy Duty brake sho

Mike / Joe

The 5464662 matches one of mine. I guess it will take some more research to determine what Morraine part #'s covered what period of time and application.

I wonder if the second half of the front shoe you are looking at has the other 5462056 #.

Maybe what I have is a set of Z06 shoes.If so that wouldn't be all bad.

Mike..I notice in the new restorer..the guy that owns the 55 six cylinder car featured..also owns an Olds Fiesta!

Re: Can anyone identify these Heavy Duty brake sho

Dave..good stuff..

If I find out more..I will post it...

Maybe by 62/63 a larger amount of metal facing was used. What I need to get are the blueprints.

Re: Can anyone identify these Heavy Duty brake sho

Joe...if it would be of any help, I have a complete set of used J65 shoes from my '66 Biscayne. If dimensions or descriptions are needed, let me know.

[Joseph T.]

Re: Can anyone identify these Heavy Duty brake sho

Frank..Not knowing..is why I asked for some help identifying the brake shoes I posted the picture of.

J56 or J65 ?

I read that the factory brake shoes are built with pairs of pads ..so primary's with 5 pads actually are ten pieces bonded together..as opposed to service shoes that are five single pieces.

The shoes I have are stamped with either 056 or 662 on the reverse side. The pads are 2 3/4" wide..so they appear to be the later front shoes.

How do the shoes I pictured compare with your used Biscayne shoes? I would like to determine the actual application of the shoes I have.

Thanks,

Joe
