Forward wheel hung out, knock because of mobility of disks........... When sharply you press a brake.On your 02 when do you get the knock?
Is it when you first apply the brakes with the lever?
Is it after the brakes grap and the front of the bike dives down from the weight transfer?
Have you checked how much is left on the pads/
Are the calipers tight?
How clean are they?
When you pull the brake lever bake is it tight right at first or pulls in a little bit before the brakes grabs the rotors?
Sorry for the questions just trying yto get more info. Lift the front of the bike on a lift and try and see if you get the same sound and where it is coming from.
I haven't had the stock wheels on my bike since 2003 so someone with those wheels will have to respond. I'll look at them this weekend but 1 mm of motion forward and back as you indicate is way too much. I know the current floating disks I have don't move that much.Friends, the reason of knock to me is accurately clear.
This movement of disks forward-back, 1 millimeter. ...
:them:Sounds like you have the wrong bolts installed. Does it knock on both rotors?
I noticed on my 2003 the front rotors have a different bolt than the rear rotor. Maybe someone has mixed them up. The front bolts should hold that rotor firm with no play forward or backward.
Attached is a picture of the bolt hole and the bolt. The lip pointed to by the arrow fits firmly into the hole in the wheel snugly up against the rotor. No way for movement.
The part number for the bolt is 3762M. There is an spring washer on the bolt used for the "floating" part of the rotors. It's part number is 6966M.
Sorry for the poor image.
