Recently I bought a mountain bike with hydraulic disk brakes.

But when I ride it the front wheel makes screaming sounds, possibly from the disk brake.

I contacted my local dealer and they helped me adjusting the brakes, and I even learn how to do it also.

But it seems the problem happens more than once, every time after I put back the front wheel and start riding. The problem is frustrating; I need about 5 minutes to adjust the brake and tyres every time.

What can I do, should I replace anything?

  • Disk brakes do that. (So do rim brakes, but not as often or obnoxiously.) Sep 13, 2015 at 14:37

  • You might want to see this question, and more generally to read up on the "bedding in" process, To an extent, this is perfectly normal (and temporary)

  • I had read the bedding in issue, my problem is the brakes doesn't make squealing sound and its work fine. The sound coming from the rotate disk brake touching the brakes pad when my front wheel rotating (without using any brakes) . Is this somehow still relate to the 'bedding in'. If so then i might have to wait n see.
