Hey guys. I have an Ap1 with roughly 150k miles. Previous owner put Password JDM drilled and slotted rotors all the way around with duralast ceramic pads. It breaks phenomenally with no vibrations or anything. Although, when I'm coming up to a stoplight, at about 6 mph I'll feel a grind/chatter in the pedal. It can be slightly heard too. Previous owner "says" it just started not too long ago. One of my friends had a similar issue with his Ford ranger and it ended up being a bent Tone ring (the ring that each wheel sensor uses for the ABS) that was throwing the ABS unit off. Does this sound correct? I couldn't find them on Majestichonda either..

 

After three years I finally decided to fix this issue.

Verdict: Right rear abs sensor was way out of spec. Over 1mm. Corrected and replaced my abs fuse and all is well!!
