over the end on top of the deck as shown. Install

the lever and install the screw through the lever and

idler/brake arm shaft (Fig. 233). Once the screw is

secured take a loop of wire or rope and hook the end

of the spring. Pull it towards you and hook the end

as shown.

the idler/brake arm clockwise so the upper tab on

the spring can engage the boss in the housing.

Rotate the idler/spring arm counterclockwise (Fig.

The brake pad should now ride on the brake drum.
