Hello, I replaced the rear shoes on my sister's 99 Elantra and noticed the squeaking noise coming from the back after a few weeks. I re-opened and cleaned the drum and parts with brake cleaner but the noise is still persisting. I was reading that I can place some anti seize on the rear of the shoe where it meets the back of the hub that might fix the problem but was wondering if this is being caused by the material on the Hyundai OEM pads? Any suggestions would be appreciated. Thanks, Nick
