    Front brake pads stick to disk

    Hi, recently I changed front brake pads, clean the calipers, and change and use brembo dot 4 oil, what happens is that brake pads do not free entirely discs. If i push just right one, and left one, then press rear brake, the wheall is tirning but not entirely freely.
    If i push just front brakes, and release only the right one, it seems that left two pistons are slightly brakes the wheel.

    Didn’t follow any procedure during brake oil change. The bike has 50000, second brake change, third pads, it isn’t original.

    I read the manual, and it seems that if a change front brake pads, and dismantle front calipers i need to first do everything on left calipers first( get the air from the system).

    Is there any catch?


    Regards.

    A bit hard to understand whats happening...
    You know it has the dual brake system?
    And how much is slightly?
    If you give your wheel a sturdy swing it has to circle 1 rotation, after that it will stop, the brakes always scrape a little.
    Did you clean the caliper pistons?
    Some air in your system does not make the cylinders do not release, it will only feel spongy in the lever.

    Than you for the information. sSo there i not any special procedure. Just from the manual, first front left side and the the right one for draining fluid, then for the rear, first left middle, and rear. in the same direction when i put oil inside..
    I disassemble front caliper and clean them.

    From the action of the front brake it looked to me like there is still air in the system anyway.

    Hi, i fix it.
    Just follow the manual, drain all brake fluids. disassemble front calipers, back calipers, and front master cylinder/pump. With compressed air drain all brake pipes, Clean calipers to move nice and smooth(pistons) and sliders. put it all together, pour the brake fluid, get all air from the system, and everything is OK now:-)

    Hi, no, it is not. After few hundred kilometers, especially if ABS was fired up, de air your brakes one more time...
