I need some help, when I use my front brake I hear a clunk sound, I took it to my mechanic and when looked at it he said that it looks like the brake pads are not fitting right, I had news pads put on and when I switch back my Super traps pipes out for the stock I could hear the front brake makeing the same sound but not as bad, this was before putting the new pads on, my question is is there a speical pad that I need to use that fit the Valk or is there something I need to do to make them fit better?
Thanks for any help ot ideas.
Steve

Well you realize they are floating calipers, which do make a clunking sound, as the calipers float on the pins. It sounds like you're saying that things got louder when you changed the pads, which makes you question whether they are the right pads Or correct assembly. I had the same question when I did my front brake pads this winter, and the feedback I got was it's normal – don't worry about it. there is extensive discussion about this if You search the forum. There's also quite a bit in the shop talk and Valkyrie maintenance pages.

That doesn't seem normal then--mine isn't scary just a little annoying as it happens each time I brake. |

Have you ever had the calipers off? What miliege are we looking at on the bike?
Crud, dirt, brake dust can build up and keep the calipers from "floating". Also, if the calipers have been off and were re installed with the wrong grease, it could keep the calipers from "floating".
What may be happening is your calipers are sticking and when you engage the brakes the calipers move more than normal making a loud clunk.
Maybe time to rebuild the calipers, maybe not, but a disassemble and good cleaning may solve your issue.

Thanks guys for the info, and I'm glad that it is normal, and yes it is not scary just something that I'nm not use to hearing becasue the Super Trapps pipes were load enough that I didnt hear anything over the sound of the pipes.
Thanks again for the info and peace of mind.
I just love this site.

Just a guess, but as the pads float on the calipers on pins, could it be the pins are rusty/corroded (they definitely get that way), and simply need well cleaned and greased. Perhaps the clunk is forced motion of the pads across corroded pins?
I clean my calipers with gun bore solvents and brass and stainless brushes when taken off (and put waterproof grease on the pins), but use S100 and mag wheel cleaner and scrub with small stiff bristle bottle brushes once in awhile before washing, between disassembly (tire changes). This may remove the grease, but my brakes are always dead smooth and quiet.

I bet you're not using OEM Pads.

If I remember right , there are a set of shims between the pads and the caliper bracket. The shims help eliminate the wear on the brackets. If they drop out , then you have to much clearence and the pads move.

Are you thinking of a Wing? Don't remember seeing any shims on my bikes. |

Check the rotor disc. It may well be from where the noise originates.
Grasp the brake rotor firmly and rotate it back and forth. After years of use,
they become loose in the disc frame and are able to move back and forth
to some degree.

there are some brass springs that sort of hold the pads in place. If they lose their springgyness you may get more of a clunk than normal.....as said they are floating calipers so a little clunk is normal
