OT: Brake shoes making noise

Rotors were checked by the auto parts store. They are true and within tolerances.

Does anyone have any ideas why they would squeak intermittently? And more importantly what can I do to stop it?

Thanks in advance,

Sometimes you get these with the pads (always from a dealer) and sometimes you don't and get to resuse the old ones.

Can also try a thin layer of the blue 'anti-squeal' liquid (not the spray) in place of the shim (if you lost'em) or between the shim and back of the pad. You can buy this in small packages at the auto parts check-out counter. You can also use high temp grease for this. Yes grease. Keep it off the pads.

The other thing to check is to make sure the caliper bolts are beautifully clean and shiny and grease them with the hi temp stuff from the check out counter.

All those parts have to move free. If not, the pad vibrates really fast causing the dreaded squeals that less than reputable brake shops tell ladies are so dangerous. The squeal hurts nothing but your ears.
