Subject: Pietenpol-List: a comment on brakesJust thinking out loud here as I clean up and overhaul the brakes on 41CC. They are labeled Cessna brakes and even if they are off of the smallest modern Cessna airplane, the C150, they should be more than anyone would ever need on a Piet. The C150 has a max gross of 1600 lbs. and an empty weight of nearly more than the Piet's max gross, not to mention 100HP as standard. Should be more than adequate for holding an A65 on runup or on a full power short-field takeoff, and certainly for landing duty. Good choice, Corky.All I'm doing is cleaning, stripping paint and repainting, replacing O-rings on the wheel cylinder pistons, and replacing the aluminum brake lines with Nylaflow tubing. The aluminum kinked when the gear folded up.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________

Subject: Pietenpol-List: a comment on brakesCorky, you make a good point about the O-rings in the master cylinders, but they really looked good as-is and even if I have problems with them, they are far easier to service than the wheel cylinder ones.One thing I did find out, that the rest of the world must be aware of but I wasn't, is that up in the master cylinder plungers there is an adjusting nut on the underside that is used to set the gap that allows fluid from the reservoir down into the hydraulic loop, and that it is pretty important to set that gap properly or else you either get reduced braking efficiency or more pedal drop as the pads wear. I was reading about brakes in AOPA Pilot (Feb. issue, I think) and there it was... .040" clearance, if I remember correctly. I think I just mindlessly twiddled with the adjustment nuts on my masters when I assembled them and now I need to pull them and set that gap properly. Since I haven't filled them with fluid yet, it's not a problem to do it.Oscar ZunigaSan Antonio, TXmailto: taildrags(at)hotmail.comwebsite at http://www.flysquirrel.net________________________________________________________________________________
