Know there's been thread either here or on Matronics, somewhere, about this condition, but it bears repeating. It is easily possible to install the piston in side out. Once brake pads wear a little, the O-ring will become exposed and a complete loss of brake fluid will occur without warning. This is because the O-ring is much closer to the in side face of the piston, about 1/8", than the out side face. Proper installation can be assured by backing off the 2 brake lining bolts about 1/8", have someone press the brakes. If piston extends by 1/8" and you cannot see the O-ring you are good to go. Sudden loss of one brake in a tailwheel airplane could really ruin your day. This check only takes a couple of hours at the most. Pictures or a pdf diagram may be helpful if some could post. Thanks.....
