On drum brakes we used to use small dabs of white Lubriplate grease on the backing plates where the brake shoes would rub to prevent a squeak as the brakes were applied. A little goes a LONG way, however, and I wonder how many rainstorms and/or puddles it took to wash it off.

Spray silicone lube might be a good alternative to petroleum-based grease.
