i got a set of avid j5's the rear brake always seemed to have disproportionally less braking power than the fronts. i am fully aware the front brakes have most of the braking power vs the rears.
i have to pull the lever very far (near the handlebars) to get a response from the brakes, and the response is good. i'd rather they be real sensitive so i can pump them rapidly with one finger.
i had the brakes bled professionally at the bike shop recently. (the bike isn't that old to begin with) it didn't solve the problem. is there a way to adjust them? how about that little hex nut inside the lever? would that fix the reach issue?
could this be an issue with the rear hose being more than twice the length of the front hose? do i have to physically pull the lever farther to push the fluid farther distances?
