    well a Bike Shop will See which ones you bought, then they will take care of the problem. The one you Bought the bike from should service
    what they sold you.

    Given your failure to be specific on which ones you are talking about..
    It is safe to say you don't know and should not attempt to go into an unknown DIY area.
    for your safety..

    The bike in the link has Formula hydraulic disc brakes. Here's a copy and paste from the Formula site regarding rotor rub:

    Rotor rub
    • Sounds Like: a rhythmic squeak or rubbing noise.
    o (Note: Some intermittent rotor noise is normal, especially with larger
    rotors. Rotors rub while cornering or while the frame is under side
    load due to flex in the frame.)
    • Causes & Solutions:
    o Bent rotor – get your rotor checked for straightness/trueness.
    o Incorrect Wheel Installation – have your mechanic verify that your
    wheel is seated fully in the dropouts, the QR is tightened to the spec
    called out by its manufacturer, and that there are no burrs or
    indentation marks causing the wheel to sit crookedly.
    o Caliper Alignment – have your mechanic check to see if the caliper is
    properly adjusted. Be sure to have this performed this after
    ensuring that the wheel is fully seated in the drop-outs and having
    the mounting tabs faced for alignment.

    Problem rubber stoppers, washers in the drum keep coming out partly. i push them in, but they keep coming out, which results in a locked wheel

    Honestly, you're not doing a very good job of communicating.

    Regardless, it may be that while the wheel was off the bike, you squeezed the brake lever, which will bring the brake pads together to a point that you will either not be able to get the wheel back on the bike at all or it will be such a tight fit between the pads that the wheel will not spin. The solution, if this is what has happened, is to take the wheel back off the bike and use a large, flathead screwdriver to force the pads back apart. Move them as far as they will go; this will put them in the proper position. Re-install the wheel, and if the brakes were adjusted correctly to begin with, all will be well.

    Ok so this is what happening now. Wheel is spinning but still is rubbing on inside, the brakes are installed, and they do release and lock the wheel when i press the lever
    i did force the pads apart with the flat head already

    so someone suggested to bleed? how do i go about bleeding if thats a way to fix the problem?
    or would i just ride the bike as is and it will fix itself?
    suggestions? thanks

    Yes i think what i did and did not know to do or not to do
    i did squeeze the brake lever when the wheel was off the bike, didn't know that was a no no with Hydraulics
    so i look forward to a suggestion and solution on this

    DOH! Doubt you'll get the piston back in with fluid in the system.
