could result in decreased braking performance due to air being trapped in the hydraulic
system. Use only DOT 5 brake fluid. See Bleeding the Hydraulic Brake System on page 5-22.

If hoses are cracked or show signs of deterioration, replace them with approved hoses designed to
handle the brake fluid specified for this vehicle.
