I recently replaced the entire rear brake system (high-quality NAPA wheel cylinders, Beck Arnley drums and shoes) to address a squeaking issue. I'm decent at drum brakes -- I have had good luck in the past setting them up on other Toyotas and Hondas, lubricating, and adjusting such that they work well without noise.
After a short amount of driving the noise returned. It is mostly apparent in reverse. Backing up with or without your foot on the brake you hear a little grinding chirp from the driver's side rear brake. The noise pulses at the frequency of the wheel rotation ("cheep, cheep, cheep").
When coming to a stop you can hear the same kind of noise when braking any harder than "very gentle." The noise typically shows up in the last 100 feet of stopping as the car is going more slowly.
I could try pulling the drum off and lubricating things AGAIN but I am starting to feel that it may be something else. Could this noise indicate excessive hub runout or a worn wheel bearing?
Any ideas appreciated... thanks
