Grinding in rear

[Anker]

Where did you adjust the shoes? There are two adjustment points. One is at the shoes where you can turn an adjustment device with a screw driver. The other is at the brake lever where you tighten the cables.

To do it correctly you start at the shoes and adjust them so they are close, but don't rub. After that you adjust the lever so it tightens after a small number of clicks. If you only adjust at the lever you run the risk that only the shoes on one side disengage from the drum.
