[Supras] More Brake caliper stuff

[Jeff Mohler]

On any car but the MK3...this is a textbook bent spindle/hub, or a
weak one where in racing it deflects.  If youve changed ALL of these
other things..man, I dunno...

Driving stress puts the caliper off center to the hub/spindle, and
forces the pistons in..which require an extra pump to get it back to
the rotor surface.


I get this in my RX7s (One of which won the NASA Nationals PTE class
and a new track record for the class at Mid Ohio this week) and I put
a spring under the piston which once were off a corner, pushes the
piston back to where it belongs so the nextbraking area has a stiff
pedal.
