Just to point this out you did make this post in the 765 Street Triple Section.

That is not a great situation to be in. A few things that you could check before you have to bring it into a shop. Find the spot on the wheel where it clicks and back the wheel off so that position is not aligned with the brakes. Run your hand over both rotors and see if you can feel any high spots on them. If you ride hard and brake hard then perhaps your rotors are starting to warp and the click is the first indication of it. Perhaps you can find a service station who will let you borrow a bit of brake cleaner just to wipe the rotors down with. Another thing might be that you have a small piece of debris caught in the grooves of the pad itself and it clicks when it passes by a hole in the rotor. A can of compressed air directed down into the pads might clear it out. Perhaps you can find a service shop that will let you use and air nozzle to blast the front brakes quick to see if there is anything stuck in there. If its not in the brakes or the wheel then the wheel bearing would be the next candidate for a clicking noise like that.

Good Luck

P.S. One more thing to consider. Does the frequency or the interval of the sound get faster as you go faster on the bike? Like baseball cards on the spokes of a bicycle, as you spin the wheel the clicks get faster (No I am not that old if you wondering). If that is the case then brakes or something on the wheel is a more likely candidate. If the clicking noise, or the frequency of it, is not related to speed it could be an indicator that its something else.

P.S.S. Sounds can be misleading, one other possibility is you could have a stiff link in your chain. I know from just lubing the chain it can sometimes click at a certain point if you have a stiffer link or the master link. Perhaps just clean the chain, something might have gotten caught in the rollers.

 

You need to get the front end up so you can spin the wheel and locate the sound. Then try levering the pads into the calipers; that will tell you if it's the pads or something in a disc or wheel bearing. I had a rear wheel bearing go that made a similar sound. And yes, it's a safety issue.

 

Check your spokes to ensure some joker didn't clothespin a playing card to them.


Seriously, though...it appears your bike has the same calipers as mine, so once you get the front wheel off the ground it's easy to remove the pads through the back of the calipers by removing the retaining pin and retaining springs. Just make sure you don't squeeze the brake lever, while the pads are out.
