> I am looking for some advice from the group. I purchased new brake blocks from Fresno, and found that I can not reinstall the brake assembly into the wheel casting due to clearance. I suspect that the expander tube has swelled as we have been using DOT3 for years. I have a second spare Hayes Brake set. The new brake blocks fit on the second set just fine, but found I have a fluid leak on one of the tube stems where it fits into the nozzel conection. The leak is from a failed rubber nozzle packing. Tried some "O" rings from NAPA as a substitute for the rubber nozzle packing but way too big.

If you installed the springs correctly,. it's very easy to install one facing the wrong way, and it all went together nice and tight, BUT when you try to slip the finished brake pad assembly onto the drum and it just won't go, then you have the wrong pads for your drum. There are two types. The part number B-27-38 is a 1 ½" curved length pad and is for F-24W46 and F-24R46 models. There is another block they sell that's 2" in length, and I don't have any idea what airplane that goes on. If you told those Fresno boys to send brake pads for Fairchild F-24 then that's on them. They're good guys and will make it right. Also when you get the correct pad, they will be snug. I think everybody just ends up sanding them down with 80 grit or something. I know the book says to shoot for .007 or .010 thousands, but I've found that is to tight. Mine are .012 thousands or in that area. That gives a little breathing room and the braking action is very adequate. Hope that helps.
