Recently the the reverse stopped working. I press the red "R" button, squeeze the left brake as far as it will go, and press the down-shift ES button to go from N to R, but nothing happens. It’s worked fine for almost 3 years until now. Since it stopped working, I’ve been pushing it backwards when needed for a while, but want to figure this out.
One thing I tried was tightening the cord line in the back by turning the adjustment knob at the end of the line. I had to turn it 15 times (an absurd amount) until it was tighter, and then I was able to squeeze the brake enough with "R" down to get the ES to go from N to R. The electronic shifting went smoothly, and it works reliably.
However, now the left brake (rear) is very tight compared to the right. It only squeezes about 25% compared to the right before the rear brakes almost lock up going fast on dirt. I don’t like riding like that.
Any way I can fix this without needing to clearly over-tighten the brake line?
