1000 psi in system - OK
piston area .7sq in - OK
1000x.7 = 700 lbs force - OK
.9sq in piston -OK
1000x.9 = 900 lbs force -OK
the leading shoes (pw brake setup) to not
need much force - OK
as the rotation of the brakes
and the friction of the lining locks/jams the
shoe into the lower/bottom anchor - ok
the rear shoes need more pressure to force the shoes to the drum ???hello??
Hey, I thought we were talking constant pressure here?
