[f-AA] Goodyear disc brake linings

[Jeff Lehner]

Does anyone know a source for Goodyear brake linings?  I think the part number is 954527 and 954526.  Univair doesn't have them.  I got my last set from Colie Pitts, RIP.

Appreciate any help.  This is for an L-16A.

Thanks,

Jeff

Email Tom Roush and see if he or Patricia Pitts still have any.

I was thinking the part numbers were 9511257 and 9511258.  The last ones I bought were off Ebay, but haven’t seen any lately.  If I get my Chief sold I will have a few spares to sell.

Also, I think they were listed on Luscombe.net.

954526 is the outboard and 954527 is the inboard per Aeronca Chief Service Manual (undated)

further the Champ Service Manual lists the outboard as 951059 and the inboard as 951047

Richard in OH now wondering why they are different numbers

[Roger Anderson]

Just out of curiosity I searched eBay.   Not the brake pads, but someone on there has the Goodyear disk brake clips listed for $14.50, NOS, and the buttons that go with them for $1.95.   

Dave.   Looks like Saturday's breakfast is going to require a canoe or raft to attend.   roger

Those parts on EBay Roger are from Don Jones

[Dave Geiling]

I got the numbers I quoted from a Goodyear Aviation Produced Division manual dated 9/1966.  I also see that it is Luscombe.org not .net.

Thats right Roger, I think the sun we got this morning is the last we will see for a while.

Richard,

That's very easy... the Chief is so much faster than the Champ that they had to use tougher brake pads!

Therefore we can conclude the outer pad (also called the Anvil lining) could be 9511257, 951059, or 954526

and the inner pad (also called the Piston lining) could be 9511258, 951047, or 954527.

And keep in mind the thicker one can later be used as a new smaller one after it wears.  roger

Well I was able to source the 9511257 at two different places but nothing for the 9511258

Classic Aero LLC $26  and at Chaparral Parts $22

Richard in OH wondering which one is the smaller and which is the larger

Or if one is resourceful they can go to a good brake or clutch shop, buy the lining material and make your own with a hole-saw.

McMaster-Carr may have the material.

  Joe,

    I did this a few years ago on a non-Aeronca. As long as it is a round puck, it's easy enought with the drill press and a hole saw with removable drill bit. I suppose you could leave the bit in the center if you didn't mind the extra hole but I've never done it that way.

   Getting the correct thickness was where I encountered a small issue. I used a cut-off disc to widen the gap between the pucks so the disc would rotate freely. The hard part was holding my breath while grinding the pucks down to size. The cut-off disc puts off lots of dust! I'm sure my method was OSHA approved,,, or maybe not.

   On the Good Year brake pucks, I don't think my process would work because the varied thickness. You would have to grind only one side at a time or find the correct thickness friction material. 

   There are quite a few lawn & garden machines using brake pucks. There likely is something running the same diameter pucks.

Just to bring this up-to-date, I just made a fresh batch of brake pads with an 1 3/8" / 35mm hole saw who's inside diameter is perfect. This time around I used brake pads from a Ford Focus who's width and thickness was just right and I got two from each pad. Next step is a hack saw to separate the brake material from the metal, very simple with a sharp blade. A small amount of work with a flat file and or sandpaper to clean the edges, perfect. It's possible that they may a little too thick for the outer but filling/grinding down will not be a problem.

On another note, I purchased 2 like new brake discs 95-30289 from Ebay which have the correct 8 1/4" OD but the ID was 5". Easy job for local machine shop to make them the desired 5 1/2". The outer notches should be 1/2" and mine were more like 5/8's. Total cost for two was $200.

I learned along the way that the clips, buttons and retaining ring were not originally used, actually had a Champ parked behind me that had one with with clips, the other wheel not which confused the heck out of me until it all fell apart. Holes were drilled, clips and buttons were purchased and it's all good now but no disc retaining rings (9530556) seem to exist, at least not that I could find for reasonable money (Univair $465). I'm not 100% sure this ring is required. All the parts are listed in the Goodyear brake catalogue here which is https://bit.ly/2OTJODK.

Yet another tip I learned is that the holes for the buttons (dot fasteners) are supposed to flared or tapered on the inside so that the button can expand. My holes were rather large from the 75 years of wear and tear so I filled them with JB Weld and then re-drilled.

Here's hoping for a trouble free year of braking.

BTW McMaster Carr does sell brake and clutch linings and I tried 2 different types neither of which worked AT ALL. The first was 'Metal-Free Brake and Clutch Lining' which while it looked right it was too soft, almost rubber like and therefore had next to no friction. I called and explained what I was doing and they suggested 'High-Strength Brake and Clutch Lining' which was absolutely the wrong stuff, that's when I reached for the automotive brake pads which end up looking like the original material when done.
