And its about 3mm out of center. I tried to put two block at the a few cm away from each end of the bented area and then jump on the bented area. It helped to get to the current 3mm out of center but wont go further. And adjusting the spoke wont fix it either. This is good enough the brake wont touch the rim when I ride but when I brake, I can feel a bump once the brake hit the bented area.... I guess most of you suggest just try use force to bend it back. do you guess have any suggestion what tool i can use to put more force on it? apparently my weight is not enough
The spokes need to be loose so that the rim has room to unbend. It needs to go beyond the final point, then spring back.
You may also have a small bulge in the rim causing brake grab. You might be able to use Channel-Lock pliers to carefully squeeze in the bulges. If the bulge is only on oe side, use a block of wood to spread the force out on the good side.
Sounds like you will have to settle for "good enough" or consider replacing the rim.
