I know from long experience that the problem is caused only by physical binding of the caliper and not from any form of hydraulic pressure. On landing when I must occasionally use hard braking to make a turnoff I often find that only one side will fail to release which eliminates the posibility that hydraulic pressure is the problem. When I have to make a takeoff from a marginal field I loosen the brakes by shaking each caliper before I get into the airplane. When I don't loosen them there is a quite noticeable acceleration of the airplane when the weight comes off the wheels at liftoff. My feeling as to the cause is that when pressure is applied to the caliper it spreads apart at the disk which puts a lot of pressure on the point where the caliper slides on the pins. Nice to know that there are two of us that are the only ones having trouble with Cleveland brakes. Bob Condon
