Fork creaks when braking

Hi everyone,

I have a Boardman adv 8.9. My issue is when I use my front brake the fork makes a horrible creaking sound. When I look at the disc brake I notice there is a little bit of play with the fork with the caliper attached. when breaking the fork moves a little, the caliper and the disc are locked solid just the fork moves. What do you guys think? Does the problem lie with the fork or maybe the quick release?


Not me but a pic I found to show the bike.

What have you done to rectify the issue? I would make sure your headset is is properly set up and all of your bolts are properly torqued to spec. If you can stand over the bike and close both brakes and rock back and forth it is a sign you need to address your headset and make sure everything is properly installed and tightened down.

Need more specific info.

You say the fork moves, but relative to what. Ie.

Does the fork move in the frame?
Does the wheel move in the fork?
Does the brake caliper move on the fork?

In other words what EXACTLY in moving? and relative to what?

try putting a shim washer under the crown race.

a quick test would be to add a few drips of oil to the gap between the fork crown and head tube.... the oil should reduce or eliminate the annoying squeak if that is the problem area...

another possibility is a loose fitting upper steering bearing where they seat into the frame....

and it might just be a need to re-set the headset preload... things wear a bit and "seat in" over time...

If you are seeing the movement between the fork and the headtube when you brake, then it's likely that the stem wasn't installed snug enough to the top of the headset or the top of the spacer or spacers that might be between it.

You say a creaking sound, so I assume that's just a brief sound and not a screech that I would call something that is longer in duration and shrill.

If it's a new bike, I'd take it back to the shop and let them do it. Just because they need to see that they didn't do it right the first time. So don't let your DIY self get in the way of that.

Thanks for your responses

I tried making a video of the problems which forced me to view the problem area from multiple angles. I think I am wrong about the fork moving. It looked like it was, in relation to the disc brake. It looks more like the wheel skewer is moving 1-3mm within the dropouts.

Found this video that accurately describes the issue. I have opted for a new quick-release hoping this will solve the problem. The QR will arrive tomorrow, I will update after I attach them.

Well the bike you show in the first picture doesn't have skewers/QR's. It appears to be a thru-axle But if it does, then maybe you've found the issue.

If you have a center-lock hub and brake disc, then are you certain it's not just that the center-lock isn't loose and needs to be tightened? That might be where you see movement too with the brakes firmly applied and rocking back and forth. I actually had my rear center-lock loosen on the rear and it did make a sound that I might have described as a creak.

If you aren't exactly certain how all the parts of your bike fit together, then you can easily imagine something being the cause when you watch all these videos. But yet it not being the real cause.

IF it is a through-axle and it's moving that much... YIKES! that would pretty much say that the Fork hole is ovalled... !
Was the cam lever in the open, or Closed position when you previously tightened the Axle?

"Wingnutting" QRs and Thru-axles can and will cause frame damage, missing teeth, and other scars.
