How to Adjust the Hubs on Coaster Brake Wheels

A coaster brake is a convenient feature found on around-the-town cruiser bikes. It is easy to engage, requiring only a swift backpedal, and virtually maintenance-free. The sealed unit of the brake protects it from sand and saltwater, if you live near the beach. Plus, having a bike void of brake cables makes for a great-looking ride. A wobbly back wheel indicates the need to adjust the hub on your coaster brake. It's an easy fix and will have you back on your head-turning cruiser in no time.

Instructions

    • 1

      Stand your bike upright with your kickstand.

    • 2

      Use your socket or adjustable wrench to loosen the axle nuts on both sides of the rear wheel hub.

    • 3

      Set your bike down on its left side.

    • 4

      Stick the cone wrench into the right-side cone, located on the hub.

    • 5

      Turn the cone wrench clockwise until the cone just touches the bearings. Turn it back counterclockwise 45 degrees.

    • 6

      Tighten both axle nuts with your socket or adjustable wrench.

    • 7

      Stand your bike upright. Lift the rear wheel off the ground and move it left to right. Note any play.

    • 8

      Spin the back wheel to check there is free movement in the bearings of the rear hub.

    • 9

      Fine tune the adjustment, if needed. For wheel play, re-tighten the bearing cone. If there's resistance in the spin, loosen the bearing cone a hair.
