 Posted: Tue Jul 10, 2012 4:03 pm Post subject: Drum Brake Shoe Width |
 |
|
Here's my problem with 1955 rear brake rebuild. I ordered new, repro rear wheel cylinders from a good supplier. The slot for the brake shoe is too narrow. My original Ate slot is .125"((3.175mm) and the repro slot is .115"(2.92mm). The cleaned up shoe surface that enters the slot is .1205"( 3.06mm). Supplier cliams they have sold many with no complaints. So, are my shoes non-standard(been on the car since at least 1974) or are my Ate slots wider than normal? Anyone got some shoes and cylinders laying around they care to measure?

Not all 356 drum brake shoes were created equal...and the Chinese decided the slots on the cylinder part didn't need to be accommodating to all..OR...whomever spec'd the cylinder didn't do the QC against all contingencies when the sample was sent back.
It's a bitch to have to spend the time, but I carefully file BOTH the ends of the shoes and the slot "a little" until I get a nice fit, add some Never-Seize and just "git-'r-done."
I think I recall the "Canadian shoes" are the thinner metal ends...or maybe others are the ones that fit the slots OK...I tend to forget pain.
What I haven't tried is seeing if the slotted end part can be swapped from OEM to Chinese versions after some clean-up.
Hey, I thought I was the designated caller to hear; "We have had no prior complaints...this is the first time...etc." How many times in this business....ahhh, we're to at least say "thanks for trying" to the vendors.
BTW, Franny's A Cab got my last NOS ATE cylinders...no problems there.

Mr. Baker:
So it is the case that one can no longer get new Ate drum brake parts?
How about disc brake parts?
(Here in the Heartland, it is a million miles to everywhere and local availability is seldom indicative of the situation in the Rest of the World.)

Mr. ENSY.
Genuwhine "ATE" parts are scarcer than chicken teeth. But there are still some decent parts for brakes.
1. Bill Brown in NEB, does the rebuilt wheel cylinders and the rebonded brake shoes.
2. Stoddard has some good stuff to.
In your case you might look at VW adjusting screws and wheel cylinder
pushrod for a better fit to
the shoes you have. Just a thought for your situation.
cheers

Stephen, that's way over my head. I see things come out of hiding once in a while.....I just found some misc. ATE parts in a stash in PA, but no vendor I know has A-B cylinders...(But a posting like this may smoke one out?)
Brake calipers, master cylinders and other parts may be still found, and I'd look on the Alfred Teves website if I needed to know. I just bought Zimmerman rotors for my C discs on my A, so quality replacements can be had...and those front rotors were "only" $46/ea. from Engine Builder's Supply.
The point I want to make here is that whether NOS or OEM or whatever, I now disassemble each brand new part, assuming the assembly lube has succumbed to "shelf wear" and dried in the bore, often causing an internal leak in a master cylinder, for instance. The fix is far, far easier on the bench and dry than taking it out after unsuccessful installation and wet. It's worth the time, found to be needed or not.
Generally, I can pick out the dried "juice" and hone the bore and reassemble the same parts to get a good pedal, first try. It's frustrating to get nice blue/white boxes with shiny new parts inside only to find they are "NOS" stock with the emphasis on the "Old" part!

Thanks for the idea of swapping out parts. I had thought of that and taken the pistons out of the Ate and repro cylinders and did not think it would work. Just took them apart today and it does work. I also am using the 40 year old Ate rubber boots as they are much sturdier than the repro ones and appear in very good shape.
Regarding the Ate wheel cylinders, my supplier carries two cylinders, this cheaper($70) repro and a more expensive one which I assume were Ate. Maybe not, eh.
