Do disconnect the cable at the caliper. I think you move the nuts up the cable to reduce slack. You can pull on the open park of the cable and feel the slack. Tighten until you have almost no slack. Do this with the rear wheels off the ground. Spin each wheel to see that the pads are not dragging. You move the adjusting screws until the lever on the caliper starts to move then back off. Test by pulling the e brake handle. It should have resistance with little play. |

Moving the cable sheath in or out by loosening the lock nut adjusts the sheath length. Moving the sheath out will tighten the cable. Do not disconnect the cable from the caliper. |

Do not disconnect the cable from the caliper. i dont get it,how does unlocking the 2- 17mm nuts on brake cable increase or decrease cable length.the nuts move on the threaded cable,but cable doesnt move to tighten or loosen. i dont see a sheath,just a solid cable with threaded end and locking nuts. |
