Step-by-Step Guide

  1. Step 1: Assembly tools and supplies: An assistant.

    New brake fluid.

    A clear container partially filled with brake fluid.

    A length of 3/16" tubing.

    A box-end (usually 7mm) wrench.

    The stock is 7 mm; if wheel cylinders have been replaced it's possible that the valves are 1/4-inch or 5/16-inch.
  2. Step 2: Ensure the brakes on all four wheels are properly adjusted.

    , If it is dirty or filled with debris, replace it with good fluid.
