My 2010 Renegade 500 makes a crunchy sound when I hit the rear brake hard. The brake pads and disk look good to me but I’m not a mechanic but I’ve replaced the brake on cars a few times. The bike has only 1400 miles on it. Since it is the 2010 previous design I think it doesn’t suffer from the newer designs thin pads problem.

(Last week I posted about this but there were some errors in that post and thread so I thought I would start fresh now that I have better info.)
