So after a tyre change it seems my rear brake isnt working as intended. It has some braking power but not enough to skid the rear wheel. When i push the lever to brake it seems like its almost bottomed out and the lever has no more room to be pushed. So far ive only bled the lines to check for bubbles. Any trouble shooting ideas? Id rather not take it back to the dealer if i can fix it at home, I.e. if its just a quick adjustment ive looked over.
