So tell us, Jim, what pressure have you tested your calipers to ? And what
temperature ?
Let's see, if we assume the driver can put 300 pounds on the brake pedal
(when his/her life depends on it), times about 7:1 mechanical advantage,
divided by about .4 sq in for the MC piston, that's about 5000 psi hydraulic
pressure ...
