Review on 🔥 Enhanced Performance Brake Kit: Power Stop KOE3054 - OE Brake Rotors & Ceramic Brake Pads by George Mack

Purchased and fitted December 2019. It has been in use for 6 months now and although they seem to be wearing evenly when braking at low speeds they make a noise which I can only describe as a hum can describe. The surface of the rotors looks like the rings of a 100 year old tree, the pads are completely smooth so I'm confused where the lines on the rotors are coming from. I'm not a professional mechanic but have done dozens of brake jobs including this being the third time I've changed the brake pads on this 2013 Rav4. It's not a safety issue, but there shouldn't be any noise in a brake part that has "No Noise" written on it as one of its trademarks.
