So I have some knowledge of drum brakes i.e. I know how to make my way through a brake job. Due to this limited knowledge, I don't have much experience with diagnosing squeaks or squeals from the drums. At first I thought it to be my front brakes and have since took them off and put brake lubricant on the pads. The noise stopped for a day or so but has started up again. I have been able to determine the noise is coming from the rear. I am not sure if there is something I can put on the drum or pads to stop or at least quiet the noise, that is if nothing needs to be replaced. Any tips on what I can do?
