Philip,
The blue sticky substance is not for gasket purposes. Your brake pads came
with some of this in a plastic tube, and it goes between the metal back of
the pad and the piston that drives the pad. It attaches the pad to the
piston supposedly to prevent rattle. You do not have to use it. If it
looks too invasive, remove it.
Hey, I hope you are enjoying your struggles with the car, because they are
reaching epic proportions. If the fun is disappearing, a good brake place
should be able to sort out your various brake caliper and pedal problems
without costing you an unusual amount? Not a criticism, just an
observation from someone who is also capable of spending a lot of time to
avoid getting paid help!
