I've got an '85 250ES Big Red with both rear brake cable adjustments (hand lever and foot lever) all the way in, but no brakes. The hand lever in particular has no braking power, but the foot lever has "some" braking.
I'm not sure what's going on here other than the arm that actuates the brake shoes isn't turning enough to push the shoes out to hit the drum. The index marks on the arm and the cam are matched up and I've done what the manual says to do...
At first I thought my cables were stretched out so I replaced them, no love.
Then I measured my brake shoes, and while in spec per the manual, were a little worn so I replaced them, no love.
I have to crank the adjusting wing nuts all the way down and compress the cable springs 100% to get what even feels like a little drag on the drum, but it's not enough to stop this beast when it's flying down a gravel road at warp speed.
What am I doing wrong here? I've had the entire brake assembly off the bike a couple of times to play with it, but it's not making sense.
