REFLECTOR: Fwd: RE: Brake Upgrade

[Chuck Jensen]

It's a minor point but the phenolic boards that are inserted between the
axle and gear leg is really a "thermal isolation barrier" rather than a heat
shield.  By installing the thermal isolation barrier between the axle and
leg, the only heat conduit path is through the bolts, which is minimal.
Main point is, they work fine.  I found after converting from the Matcos to
Clevelands (XL RG 300) that there is very little heat build in the brake
assembly anyhow, so the barrier probably doesn't do much.

Al,
Sounds like maybe you are thinking of using the compound brakes. I 
have them and they work great. I do have a heat shield made out of 
phenolic between the gear leg and the axal.
I do not feel that the clutch master cylinders we use are the best it 
seems to me that the brakes are better and have more than i can apply 
with the clutch cylinders.
There is a Rev A to the 323 compound brakes that must be completed.
I have close to 300 Hours on the brakes now and the first hours taxi 
tests etc were probably pretty rough. I know the first landing was.
I am sure you know that the 323 brakes are a completely different 
brake than the AT or XT etc.
