While on my way back from Alaska last week on my 2001 Wing, I started feeling a "bumping" whenever I applied the brake pedal. It feels like maybe 1 "bump" per revolution. When I got to my Nephew's house in Mt. Vernon, Washington, I checked the brake pads and the front pads were worn out. One had just barely gotten down to metal, but hadn't damaged the rotor. I bought new OEM pads from the Honda dealer and installed the front ones in Washington. The rears didn't look bad. I rode the bike from Washington back to Salt Lake City, Utah and I could still feel the bumping when I applied the brakes. I'm now back home in Tennessee and put the rear brake pads on even though they weren't worn out. Does anyone have an idea what the bumping might be that I'm feeling when stopping? It doesn't seem to do it as badly when I use only the front brakes?
