Hello Vance, Several KIS builders / flyers at Osh Kosh in 1997 made comments
that convinced me that the brakes needed improvement. Here is what I have
done.
1) Strengthened / stiffened the floorboard / tunnel area to reduce flexing.
2) Installed larger aluminum plates for the rudder pedal blocks to be
fastened to. This also reduces floorboard flexing.
3) Replaced the Matco brake pedal cylinders with the self contained resevoirs
with Matco brake pedal cylinders that take a separate resevoir. The Lancair
community had bad things to say about the former. I would have preferred to
go with Cleveland equipment the whole way, but by the time I directly
addressed the brake issue I had had the Matco hardware too long to return it.
(I wish that I had been given the option at the beginning of purchasing my own
brakes, wheels, and tires. Who wants to fly for the first time with tires
that have lain around xxx years during the building process?)
4) Riveted aluminum angle plates to the kit provided steel rudder pedals.
These angle plates are 3 inches wide, 5 inches long and have a 1 inch vertical
angle. They are riveted to the steel pedals such that the top of the aluminum
plates are 1 inch above the top of the steel pedals and the 1 inch vertical
angles are 1 inch farther apart than the existing outside edges of the steel
pedals. These aluminum plates do the following: a) Increase the leverage on
the brake piston end when applying pressure to the top portion of the rudder
pedals. b) Provide a larger surface for the sole of the shoe to push on when
applying pressure on either the brakes or rudder pedals. c) Allow your feet to
be farther apart when pushing on the pedals (I don't like the feel of rudder
or brake pedals that are too close together. d) Lets you know exactly where
your feet are left and right with respect to the pedals when the outside edge
of the sole of your shoe is up against the vertical angle.
