Rear brake clicking ?

[Aquaman]

This may just be a coincidence but ever since I installed the Wolo Bad Boy horn I've noticed a clicking noise when I apply the rear brake while I'm moving. Anybody else ever experience this or could it be something else ? Any thoughts or feedback are greatly appreciated.  Michael

Guessing you installed the horn under the swingarm?   Did you lift the bike when you installed it?  How many miles?  What model?  Did you do anything else when you installed the horn?  How did you mount the horn?  Pics?

99 Standard - Did not lift the bike - 24,000 miles - Did nothing else when installing the horn - Mounted it just to the left of the fuel petcock.

Coincidence.  Sounds like it to me.    Have you done a drive inspection/maintenance?  Is the rear caliper moving freely? Any way the axle nut could have come lose?  Lift the bike and check the rear tire for incorrect side to side movement.  Check your rotor for trueness and your pads for wear. Check all nuts and bolts for tourqe/tightness.
