Brake Cables

Taylorcraft brakes are, of course, mechanical brakes actuated by cables.  The original size of the cables is a matter of some discussion.  Some say 1/16" cables were original, others say 3/32".  Adding to the confusion is the fact that most "T"s are now equipped with 1/8" cables which are standard for all other controls.  But the fact is the cables need to be quite flexible to go around those little steel pulleys...and 1/8" is just too large.  Then there's the reports of 1/16" cables breaking...breaking strength of 1/16" cable is 480 lbs., but one can easily imagine a panic stop with a 200 Lb. pilot stomping up to, well, 480lbs resulting in brake failure.  That leaves 3/32" cables, delightfully flexible in the 7X19 version with an astounding 1000 lb. breaking strength!

The cables are connected to the pedals with adjustable cable clamps.  Behind the pedals, the parking brake is connected with another cable clamp. (see Photo 1)  At the wheel, the cables are connected to the brake bellcrank with a nico press sleeve and thimble...and two steel links.  (see Photo 2)
