its a 03 600rr with 16500 miles. coming to slow stops it has a lunging effect. like the brakes will grab and let loose over and over like its throbbing. on quick stops it does the same thing but alot worse. somtimes i think i can hear a grinding noise coming from the fron but it is hard to tell because ive only had the bike 3 weeks. Any ideas? brake pads look fine i pulled the calipers yesterday.
