Re: Anybody want a new friction tip for their vacuum brake?
You could also use a brass shell casing for a punch.

Re: Anybody want a new friction tip for their vacuum brake?
I bought the best 5/8" hollow punch I could find and I have to sharpen it every two or three discs. That stuff is tough. "slowforty" - Sorry, but this stuff would eat a brass shell casing for lunch. I'm still kind of amazed that "Admiral" was even able to find a Shoemaker; there aren't any around here anymore.

Re: Anybody want a new friction tip for their vacuum brake?
Once a new disc is installed, what's the best initial setting for the adjustment screw?

Re: Anybody want a new friction tip for their vacuum brake?
Yep, they seem to make the rules up according to the person at the point of lodgement. One thing is for certain, sorting equipment checks for envelope stiffness - to stop damaging the mailpiece. Seal the envelopes well so they don't come apart if the stiffness detector is faulty.

This is the punch, a simple piece of mild steel bored to the appropriate diameter with a tapered cutting edge on one end. I used a piece of scrap metal for this since it was free, easy to machine and I'm not making hundreds of these so if the tool gets dull it doesn't really matter. Here's the disk, which is easily cut from the shoe heel, either by setting everything up in a vice and cranking it closed or -- if you're the particular sort -- you can do the same in an arbor press. The former was dead simple and took about five seconds. As mentioned by others, I jammed this leather piece in there with a touch of super glue to hold it fast. After this, I oiled it well and installed it. And here's the plunger/piston it attaches to. And a correction, the leather appears to be about .205", not .250" as I initially indicated. Still, it seems to work just fine in my car. No complaints. Hope this helps! Last edited by Admiral; 12-27-2017 at 11:59 AM. Reason: To add one more thing... |

Re: Anybody want a new friction tip for their vacuum brake?
Funny. Even with my "High-Class" purpose made hollow punch, I was not able to press it through using my vice. The arbor press was even less effective. I ended up boring a 7/8" hole through a 4X4, inserting the punch, laying that on top of the leather on top of another piece of wood and hitting it as hard as I could with my biggest sledge hammer.
I sure wish I would have known about these other sources before I went to the trouble. Oh well, if anyone else needs one, there is a source. As an aside, I don't think the .205 would have cut it with the Mallory distributor; any wear and it would have been metal to metal. |

Re: Anybody want a new friction tip for their vacuum brake?
I never heard an answer to GB's question about initial setting of the break. What is it? Al

Re: Anybody want a new friction tip for their vacuum brake?
It's my thread, but I can't help because I got into this because Mallory leather tips are the same size (diameter anyway) as those in a Ford. I'm sure "Bubba" or some of the other guys know. In the final analysis, this thread is probably not the best place to ask, since it has turned into a critique of the USPS and my pricing.

Re: Anybody want a new friction tip for their vacuum brake?
With modern fuel the pressure on the break donīt have to be much.
As long as you have it rubbing with no vacuum it will work...then you can adjust it in if needed under hard running of the engine. 2-3 turns in from full out is where i start. |

Re: Anybody want a new friction tip for their vacuum brake?
Instead of a punch, wouldn't something like this work better?

Re: Anybody want a new friction tip for their vacuum brake?
That one (and several others on Amazon) looks good. Unfortunately, I have a lifetime supply of discs already.

Re: Anybody want a new friction tip for their vacuum brake?
I just received my 2 tips from tubman (Thanks Denny)--After removing the old tip I realized that the opening for the tip is crimped about .050 at the outside end--I turned a short taper on a piece of 5/8" round and pressed it into the opening to allow the tip to be easily pushed in--Then I bored a short taper in a piece of round stock and pressed it over the body to re-crimp the outside edge--There is no need for any adhesive to hold it in place--I have the brake/tip soaking in lubricant now and will probably use some silicone grease as recommended by Bubba when I assemble--This is for my back-up dizzy--

Re: Anybody want a new friction tip for their vacuum brake?
I still have the leather and the punch and can send you two for $7.00. If you can get the equivalent cheaper some where else it won't hurt my feelings; punching them out is no fun.
As a matter of fact, I think I have one disc soaked in MMO left; PM me your address and I'll wrap it up and send it to you for nothing. I'll send it regular mail, and you should get it, but no guarantee. Last edited by tubman; 05-12-2018 at 06:04 PM. Reason: Grammar Police |

Re: Anybody want a new friction tip for their vacuum brake?
I have found that on some Ford V8 distributor brake pistons that the recess for the leathers are of different diameters.
