So, of the 5 tool sets you bought, that was the one size you didn't use?
I know, right? It's funny now, but I gets frustrated when it comes to tools. I can never find the one I'm looking for. It's like they are always hiding from me. lol
try opening the front brakes buy the handle bar lever pump theam a few times to see if anything falls out spin the tire back and forth maybe wash with water or add some high pressure air to theam to force out what ever might be in there.
Thanks, blue. Went to workin' it for a few minutes, knocked some dust out, but that's about it. I'm thinking those scratches are the culprit at this point and whatever caused them is probably long gone. It feels a bit sharp on the edge of one of those scratches and the noise sounds exactly when those scratches are behind the pads. Don't know if there's a solution for that or if a new disc is in order, but I'm done with it for the night, too tired, lol.
