G-60 Caliper pins

[Kneale Brownson]

The right front brake has been binding up the last couple of days.  I got
the caliper off and the top pin has a definite looseness.  I can wobble it
back and forth inside the bracket even when the boot is fully compressed.
Is this the likely source of the binding?  The bottom pin is snug in its
hole.  Both were lubed within the last eight or nine months.  I bleed the
brakes every time I switch from summer to winter tires or back, so I don't
think the fluid was bad (except now, of course, after the overheating from
the binding).  I'm going to replace the bracket and pins, but I just
wondered if the looseness could cause the pin to not slide properly and
release the pads.
