ININGS
The lining material used in the Sportsman brakes is an asbestos based
organic compound. To provide the maximum service life, the brake
lining material must be properly broken-in by gently heat curing the
resins, as described below. Excessive heat applied before curing will
carburize the lining material, lowering the braking coefficient and
reducing the service life of the linings.
To break-in the new brake lining material, perform a minimum of six
stops from a speed of between 25 and 40 m.p.h., using light pedal
effort and letting the brakes cool partially (about one minute) between
stops. This procedure generates enough heat to cure the resins in the
lining, yet will not carburize the material by heating excessively. Once
the linings are properly cured, they will provide many hours of
maintenance-free service.
7-9.4.2 Bleeding the Brakes
To bleed the brakes, use a fluid pump (such as an oil pump can) with a
clear tube attached to the brake caliper bleeder fitting. Open the
bleeder and pump fluid from the caliper through the master cylinder(s)
to the reservoir until no air bubbles are evident in the reservoir; then,
tighten the bleeder fitting. As the reservoir fills, siphon the fluid back
down into the pump or some other container to prevent overflow.
Repeat for both brake calipers until the brakes feel solid. Finally, drain
the reservoir until it is about
7/8
full.
