High pitched "sching" sound

[esie]

I was riding along on my way to uni, and a high pitched "sching" sound (like a metallic sound) started, I think it is coming from the front. Well, I know that is far from an official explanation, but that is what was happening!
I had been using the front brakes a bit, as I had gone through several zebra crossings with people on them, speedbumps, & roundabouts.

The braking seems unaffected (but I was only travelling slowly), I couldn't see anything wrong, so I parked the bike and came back to it four hours later. After I tagged some other bikes with KSRC stickers, I got back on the bike, started him up, and he sounded fine and the sound didn't return. The bike has got 26,000kms on it, and is well and truly overdue it's 24,000km service. Could it be the brake calipers sticking? If so, would using some brake and disc cleaner help?

Thanks!

That sounds like the new audible warning devices that brake pads are now being fitted with,my van did the same thing a while back and my mechanic told me that they were originally made for taxis but were such a good idea they now put them in all pads.

I think your bike has been listening to too much Robert Palmer.

Maybe a stone stuck in the pads, and when you got to where you were going you reversed it into the park which caused the stone to fall out

You might as well face it.

I confer with ya Paul this is the most logical reason.....
I once had a BMW rs1100 & was doing the second stone run when the clutch stopped working?
Cable still opperated & everything I could see seemed fine..
Turned out to be a stone wedged between the actuating arm & engine... bugger had it towed & all for somethnig as easy as a errant rock!

Esie I would still use some brake cleaner perioidically to clean out all the muck that acculimates round the pads & such.

Thanks everyone,

Jeff came home from work at lunchtime, and took my bike back to work to hear if it occured again, which it didn't. When he got home we got the bike up on the stands and gave the front and rear brakes a good clean and did the chain while we were there. I'll see how it goes tomorrow.

When my gpx lower cowling was hit by a half brick flicked up from the truck 40 foot in front of me, the whole bike vibrated and sounded like a fricking bell, *CLANG*, could have been simething that managed to hit his disc in a fluke shot mebbe?
