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? – mattnz Apr 11 at 20:23
  • Yeah, both brakes do the same thing sadly,headset definitely not loose, new bike. Brakes are shimano mt400. Thanks for the comment – PlaneSIMple Apr 13 at 2:12

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. – PlaneSIMple Apr 14 at 12:09
