I am driving a 2003 Honda Accord. I changed my brake pads and rotors for all 4 wheels a few months ago. They are CENTRIC PLAIN 120 SERIES ROTORS. and Akebono Pads. the first week after I changed them, there was no noise at all. But it started after a week or so. It's a low-pitch grunting noise that goes like gerr..errr.gerr..gerr. when braking at low speed. It doesn't happen when driving at high speed. It only happens at very low speed when given more than half of the pressure. Here are some photos of the four wheels' current conditions. front and back. I don't know if the pads and rotors are the problems or that I did something wrong. Please help. Thank you
Common mistakes are not cleaning rotors with brake cleaner and not seating pads and rotors after installation. Also neglecting to lube slide pins and rails that pads slide on. The only thing I can think that might cause this is maybe forgetting to clean rotors. Or calipers are not releasing due to faulty calipers or bad brake hose. Seeing as more than 1 rotor is affected, I'm going to also guess poor rotors. When you replace the rotors make sure the wheels spin freely after you apply and release brakes.
