Kah-cloonk from front brakes. Normal?
«
on:
May 12, 2008, 11:40:13 AM »
When I push down the fork, no noise.
If I do the same with the brake on, kah-cloonk noise. It's like some brake parts are loose.
What do you think? Normal or is it time to check things out?

Something is probably haywire, but it depends on how loud the noise is.
tough to say via internet...
Try to isolate where the noise is coming from first.

Does it also make the sound if you have brakes on and try rolling the bike forward (w/out compressing the forks)?

Yes, I roll it back and forth with the same noise. The level of noise is
about
the same as if I drop a lighter from an inch onto a table top.

Can you tell if it is the from where the unit mounts to the fork or internal (like from the pads)?
Has braking ability been reduced from before?
...Perhaps it is time to check things out as front brakes is crucial

I will try to determine where the sound is coming from, kind of difficult on my own, but I'll try to get someone to sit on the bike and brake for me.
Brakes perform like they use to. The bike and I are going to the dealer in two weeks, but I'm not going to ignore it for two weeks. Midnight here now, so I'll be checking in with you guys tomorrow.
Thanks a lot

Mine does it too.
My tech says probably fork busings.

Do you think so, after only 4k miles?

Maybe, though I'd hope not yet on an '07 bike.
Steering head bearings maybe? Not wanting to point the finger at the OP, but you haven't been learning to wheelie on this bike and had a few more hard landings than you'd like have you?
One other thing it might be - don't those 800's have the lower spec front calipers? I know they're black not gold (at least on the Australian delivered ones), but I'm not sure if they're still 4 piston or if they went with 2 piston sliding calipers? If they're sliding calipers like my old Honda's got, you might have some wear on the pins or bushes the calipers slide on which can make a bit of noise...

The S2R 800 did indeed have the 2-piston sliding style caliper.

I'm not sure what brakes I have, but I think there are 2 pistons and that they might be sliding/floating or something like that.
Yes, lower spec and black.
The noise is coming from the calipers. I shook them and they are kind of slightly loose to either side and it seems like the pads move a bit in the rolling direction when I push the bike back and forth with the breaks applied.
Not any hard landings yet, just a few inches off the ground now and then - it's only a 800 and I'm new to this bike

It very well might be just that - I'm just trying to make sure - as mentioned above the brakes are kind of crucial [moto]

mine does the exact same thing. only clunks when moving back and forth with the brakes engaged. but not if they are released.
it's just pad movement, imo. check it out, for sure... but i'm betting you'll find it's normal
