REFLECTOR: Why you don't want to be overweight on landing....

[Jim Agnew]

Brian,
 
The Cleveland's have the calipers mounted on the outside of the rotor and have a larger moment arm so the applied brake pad friction is more effective.
 
Sodium cooled items like valves have some sodium in the hollow stem that melts and sloshes back and forth carrying heat from the hot end to the cooler end.

Did you ever post my writeup on the rotor disk slotting?

Agreed.  Kinetic energy must be converted to heat in order to stop.

So, why is it that the Clevelands perform better?  Do they have a higher 
thermal mass?  Does the brake material ablate away, throwing off the 
high temp caliper bits?

We have sodium cooled rods which I find a dubious benefit (would like 
for someone to explain that one to my satisfaction).  However, we don't 
have sodium cooled rotors.  Seems like phase change from solid to liquid 
would do wonders for brake capacity.
