Can you ID these calipers?

Last summer I installed disk brakes on my 14 bolt. I bought the "large GM" calipers from TSM (see http://www.tsmmfg.com/3120.htm), which are different from the cadillac calipers. I hope the "only available from TSM" is something I can work around!

I have developed a leak around the parking brake lever stud, and would like to find the stock application so I can find a reman caliper locally.

Do you know what these calipers are originally from? (or whether I can buy a rebuild kit for this one?)

Thanks!
 
AFAIK the only rear caliper that has an e-brake that will work with the 14ff conversion is the caddy eldo 1976-1978.
 
Unfortunately, these calipers are not caddy calipers, and I am currently using them on a 14 bolt disk brake conversion (almost a year now)....which leads back to my original question...what did they get them from?
 
What makes you think they aren't caddy calipers? Those are the only calipers that i know of that have the correct bolt spacing and also have the width to fit the 3/4 ton rotors.
 
Well, I thought the same thing...maybe caddy calipers, but the problem is the TSM catalog clearly shows two different calipers.

take a look: left = caddy, right = mine (large GM, and the caliper is upside down in this pic)

BTW, I have emailed them in hopes of more info. No way am I paying $320 for two new calipers...
 
the caliper on the right is a caddy eldo caliper with either fleetwood and or seville brackets and springs, this is what i'm going to be using.
 
Thanks for the help. I guess TSM is being mis-leading with their catalog. I will get a rebuild kiy for the eldo calipers and see what happens.
 
if you got the springs and all the brackets.. just goto napa and buy you a new set.. new caddy calipers cost me $60 each... the only thing is they dont come with the springs nor levers.. and the reason why they are so expensive is the core.... $60 each plus $60 core each... = $120 x 2 = $240........ WITH NO SPRINGS!!!! so as long as you have the hardware you are in good shape :wink1:
 
Thats what I'm thinking. The TSM catalog just makes it look as though they were not caddy calipers, but after more research, I think they are.
 
I just got an email from TSM...4x4HIGH you are 100% correct...76-78 eldo calipers. :bow: All I can say is their catalog is misleading!


hmmm, what are the other calipers...

The pix hide the fact, but they'er BOTH 76-78 Eldo calipers.

The difference is the parking brake linkage; one goes under the caliper and one goes over, so to speak.

Now why in the $#@$ would they do that?
 
Rather than rebuild the calipers, or order a new one, I put a wrench on the nut holding the parking brake lever and after a couple of short drives, it looks as though the leak has dried up.

So that folks who want the parking linkage above the axle, out of harm's way, can get it. Otherwise you either gotta mount the caliper upside down, to get the linkage up, and put up with miserable bleeds, or mount the caliper right side up but have the linkage down where it can get stuck on rocks and stuff.

That said, I have regular Caddy calipers, so what do I know.
