Brake noise

A mechanic said that the brake shoes have 60-70% lining left, and didn't notice any obvious problem. He suggested breaking the glaze on the surface of the brake shoes. I don't know if he thought that would solve the problem or if it was just the only thing he could think of.

The noise must be getting worse because now I can hear it clearly, whereas previously only my wife could hear it. My wife handles most of our mutual hearing needs.

Thanks, Stan

Thanks again, and Happy New Year

The clearance I was trying to convey is only 1/2 in. from the trailing end and the front end of the shoe/pad, not the entire shoe/pad surface. We, in the repair industry, call it toe and heel clearance, that procedure does not allow any debrie/rust to get to the main portion of the brakes, and usually does the trick.!
No offence taken.

first stop after rain would cause the howl, we would come out of church and try to not use the brakes in the parking lot as the noise was very loud on first stop

I pulled drums and cleaned all the dust out but noise came back right away, Dodge dealer refused to fix it under warranty, said all of them did it, traded the car in on ranger

last Chrysler product I will ever drive
