Jeff Edwards,
I found this post you made
earlier and was wondering if you found and fixed a problem or not?
thanks,
Colyn

I recieved a
reply from Ralph Hartlaub at Cleveland Wheel & Brakes. I met Ralph at the
Lancair tent at Oshkosh. Hope you all can use the information.

Hello Jeff
I
certainly do remember our conversation. The brake that you have is a
30-233.
The 164-02504 is the brake disc part number. The 199--224A is a
conversion
kit (bill of material shown below) that upgraded the caliper
from an organic
to a metallic lining. The torque plate would be mounted
with the same with
either lining configuration. A simple check to
determine if the torque plate
is orientated correctly is to sight or lay a
straight edge on the outer
surface of the brake disc. The torque plate
anchor bushings should be
approximately flush to +/- .050 above or below
that surface. This can be
accomplished using the proper length inboard
bearing stop and torque plate
oreintation. As you can see in the sketch
below, if the torque plate were to
move to the right relative to the brake
disc then eventually the torque plate
could come into contact with the
pressure plate thereby limiting the clamping
pressure on the brake disc as
the pressure plate lining wears. If torque
plate is located too far to
the left then you may not have enough anchor bolt
to torque plate bushing
engagement and will compromise the torque take out
ability. See sketch
below. If you have any questions, you should talk to Kit
Components and
have them send you installation information for your
aircraft.

The 40-406/30-233 has a KE rating for each wheel
and brake of 425,000
ft-lbs at 80.76 mph and an IE of 1965 lbs. Unless
otherwise specified by
the aircraft manufacturer,typically the simplified
mininum KE requirements
for a type certificated aircraft is defined by FAR
part 23.735. Please
see the information below. It has been copied from our
50-76 drawing that
is widely used by the experimental aircraft homebuilders
to select
products.

Here is a copy of the parts that were furnished to
upgrade, the 40-96E &
30-61E (organic lining) to the 40-406 & 30-233
(Metallic Lining) wheel and
brake configuration.
