[TR] caliper piston pop-out?

[dorpaul]

List,
I rebuilt my caliper brakes relatively recent.  Even more recently, while
attempting to bleed the entire brake system, I realized I had accidentily left
out just one brake pad during the procedure.  Of course, the pedal pressure
had driven that one piston up against the still rotor (and doing no harm,
except it should have contacted a  brake pad instead of the rotor.)

Fortunatly, by using several screwdrivers and loosening the bleed nipple, the
piston traveled back into it's 'pot'.  I guess I'm ok since everything works
now, but, I wonder if something like the o-ring-like piston rubber would ever
get twisted, come out-of-grove or not 'correctly center' itself on the
traveling piston if ever this ever reoccurs?  Would the piston 'push-out' so
far as to establish a leak or take in air?  I think the rotors have rarely
been 'turned' since they look thick(maybe 5/8" thick).

Thanks, Paul Dorsey  60 TR3
