brake cable routing
I am restoring a champ, and have just fabricated 3/32nd brake cables, I have them attached to the rear brake pedals and routed through the lower fuselage member cables guides and up to the area of the axel strut, I know they must go through the fabric to the axel strut then down the strut etc, BUT what keeps the fabric from tearing when the brakes are applied? can't find anything in the books on this. thanks, jack

CABLE HOUSING
You will find a clip welded on the upper part of the strut. Run the housing
between the two ears and secure with a bolt and nut. If you do not have
this clip and none was ever there you have a strut made for the hyd. brake gear. Mfg. one and weld it on. The gear is NOT HEAT TREATED.
For ref. see page 36 in the L-16A & B parts book.
Best of luck
P.S. When installing the upper part of the strut, don't forget the bushing
P/N AS5-5-902. It is not shown in the 7-AC Manuals.

I don't know if it's the way they came from the Factory but mine was set up like this: The housing was attached to the frame at the "ears" that Lowell described, then the housing was directed to the center gear fitting. The shield was zip-tied witha a standoff to the gear leg at the very top (where the leg tapers), to keep it from tearing fabric. Then it goes down the gear leg.
Be sure to run the brake cable through a piece of plastic tubing down the gear leg, or the cable will bang away at the paint.
One other thing from experience, take a good look at that "ears" fitting in the fuselage. Mine was broke when I bought the plane (unknown to me) and they had repaired it by attaching the "ears" to a piece of .032 alum. and hose clamping that to the frame!
Anyway we picked up on it the first annual, but wasn't much we could do until a recover. I didn't like the idea of welding a new piece on with fuel/oil soaked fabric 4 inches in all directions. So we let it be until it became frail and wore through the brake cable. Made a saddle with the fitting attached to it, and secured it to the frame. No problems since.
You can find some wild repairs when you take a look in your plane!
