diesel2607 Posted August 22, 2017 Report Share Posted August 22, 2017 Hi just been out on my bike and felt the front wheel was knocking when I have the front brake on and gently push the bike forward and backwards you can see the brake disk is still but the wheel is moving causing a knocking feeling Does anyone know what could be causing this I had front wheel off and only have one washer on the brake disk side between the fork and the spacer not sure if this could cause the problem or if I am meant to have anotger washer the other side Any help with this would be great Quote Link to comment Share on other sites More sharing options...
tshock250 Posted August 22, 2017 Report Share Posted August 22, 2017 Is it a floating disc? Quote Link to comment Share on other sites More sharing options...
rotors7 Posted August 22, 2017 Report Share Posted August 22, 2017 It sounds like it could be the 'top hat' washers that go through the disk are worn. Really really badly worn wheel bearings.. Or it could be your steering head bearings, but then the front wheel wouldn't move slightly. Quote Link to comment Share on other sites More sharing options...

lineaway Posted August 23, 2017 Report Share Posted August 23, 2017 Still have the plastic disc guard on? Seems like I remember the caliper bolts could do some damage if the guard washers were gone. It made the mounting bolts too long. Quote Link to comment Share on other sites More sharing options...
lopez Posted August 23, 2017 Report Share Posted August 23, 2017 Correct, first time I had the front wheel off I forgot to replace the disc guard and one of the caliper bolts protrudes too far if you do that and hits the disc/wheel assembly. 1 Quote Link to comment Share on other sites More sharing options...

anotherfive Posted August 23, 2017 Report Share Posted August 23, 2017 I think it'll be your head stock. Floating disc does move but does not feel too bad through handlebars.Put a finger over the headstock end and move bike. Can you feel movement while applying brakes? If so that's it.

I shortened the bolt and could not understand how I mixed it up, only to find the guard behind a shelf 3 months later. To be fair, I stripped the bike when I bought it. lol Quote Link to comment Share on other sites More sharing options...
nzralphy Posted August 25, 2017 Report Share Posted August 25, 2017 Just a heads up that some of the noise and movement will come from the pads moving within the calliper Quote Link to comment Share on other sites More sharing options...
jimmyl Posted August 26, 2017 Report Share Posted August 26, 2017 If floating disc then try some silicon on the top hat spacers to take out some play. Check non of the disc bolts have come loose catching the fork/caliper as tyre goes round. as other say -check wheel bearings and head bearing etc Quote Link to comment Share on other sites More sharing options...
