Volks,

Changed the front brake pads on my 91 GL (197 k) yesterday since the
wife was complaining of a metal sound on braking.  Sure enough on the
driver's side the inboard (piston side) pad was fully worn, yet the
outboard still had a lot of life left in it.  The passenger side
looked fine as well.  Put new pads on both sides, but I'd love to
prevent this from happening again...  The calipers are newish Girling
ones that I installed last spring, and the slider pins (?? what are
those things called ??) on the calipers seemed to move smoothly.  Any
thoughts?  The brake pressure regulator just controls the pressure
between front and back, no?   Could the pad have simply broken off?

Thanks,

Dan
