I am having some trouble with my Boardman Mht 8.8.

Whenever I press my brakes while stationary, and move the bike with them engaged, a creak and clunk sounding noise appears, every time. This actually moves the wheel slightly, which is slightly worrying.

I am puzzled, my 2 local bike shops say it's normal with hydraulic disc brakes, they say its the brake pads moving around, but I beg to differ, it just doesn't seem right. And help/feedback would be greatly appreciated. Thanks : )

  • Are you sure its in the brakes, could be headset is loose. What make/model brakes?

  • Yeah, both brakes do the same thing sadly,headset definitely not loose, new bike. Brakes are shimano mt400. Thanks for the comment Commented Apr 13, 2020 at 2:12

I think the shop was right - it’s just the pads moving around in the caliper. The creak occurs when the rotor is moving extremely slowly (like in this case), and the clunk is the sound of the pads hitting either end of the caliper AND whatever fork play you have AND whatever headset play you have. Try pulling on the brake really really hard and see if that makes a noise still.


My sons bike runs MT400's -they do not do this on his bike. Shimano make quite nice brakes, even in their lower end ranges so I would not expect this. While there is movement in the pads, the tolerances are tight enough its not usually noticeable.

One possibility, the lever is not compressed enough and the disk is moving a bit. Ultimately it does not matter if brakes don't work well with static friction or are a bit noisy - bike is stationary - so it might be as simple as there a little movement before the bite kicks in.

Other than that, the movement could be caused by only three things - loose disk rotors, loose calipers or loose axle. Given its both wheels, I consider this unlikely.

That's not much of an answer, so what can you do? If the bie shops have seen the bike , I would go with their opinion. there is unlikely to be a problem. If they have not actually inspected the bike, I would be checking the tightness of the disc and calipers.

Any chance the wrong pads are installed?

  • Thanks for the informative reply, yeah thought it seemed off for a good bike to be doing that. The wheel does move slightly when doing this. 100% could be the brake pads, it was built by cycle republic (halfords v2) so anything goes haha. Commented Apr 14, 2020 at 12:09
