I am getting a sort of knock, or snap noise that sounds like it is coming from under the front of the fuel tank when I apply the front brake in slow traffic situations. Does this sound remotely familiar to anyone?
Wouldn't say it was normal.
Had a similar issue. Can't say it was the same one, but I had new pads installed and the pad spring on the right front brake wasn't in right, allowing the interior pad to "float" so when the brake was applied it would shoot up to the top of the caliper and make a rather loud "clank" sound that appeared to come from the fender area and at times sound like it may be something under the tank banging around. Usually sounded like something hitting the fender. Usually the sound was prevalent during slow speeds though you could hear it at high speeds if you knew what to listen for through the wind and road noise
Drove me nuts. The fender amplified the sound. It would also make the same sound when hitting moderate bumps in the road.
One day, trying to get to the bottom of this, I pushed the offending pad with my finger and the fender goes "Clank".
Realigned the spring and problem solved.
