Three Cheers for the ability of the new list's to include pictures (less than 100kb). Well done Mark Langford, Thank You!

I took mine off and measured them last night, and they are the very common 1/2" x 3/8" .070" diameter o-rings (although they are called 1/16"...go figure). It turns out I have a dozen of them here already, and they're going back together today. Right now the cylinders are soaking in kerosene, which does a great job of dissolving petrified hydraulic fluid. In other brake news, the "cup seals" on my Enginetics brake calipers are also a common standard seal, and I have four of them on the way now. MCP Brake still makes (or at least sells) brake pads for these, as well as "all parts except the housings". The housings are pretty durable though...there's nothing much to wear out, and the ones on N891JF still look like new. They are dirt simple, with essentially two moving parts. John Shaffer used to sell these and still has them on his plane, and says they will lock his brake to the point that the engine skids the tires on full power runup. That'll be a huge improvement in the way they were before. One pad was broken in three pieces and soaked with hydraulic fluid, and the other side had air in it, so there has to be room for improvement! I have pictures of all this stuff, and will work up a web page later, but for now, see enclosed photo of the disk/caliper parts that make up the assembly. One other point I'd like to make is that when changing tires, these Asuza wheel halves are about ten times easier to separate than the Clevelands on N56ML! Might as well put new tires, tube, and bearings in while I have all of this stuff off the plane. Now that I have the plane here and have no real schedule, I can't stop myself from "renewing" as much as I can do before it flies again. When the plane is sitting at the airport ready to fly, it's difficult to force myself to bring it down for a few weeks to do something like overhaul the brakes, but it's an easy decision when there's so much other stuff apart that flying it is months out. I'm coming to realize that I derive a lot of satisfaction from making old worn out stuff like new again. I highly recommend it...
