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.

tainer, remove the reservoir cap, and allow fluid to drain freely from the reservoir container.
If hoses are cracked or show signs of deterioration, replace them with approved hoses designed to
handle the brake fluid specified for this vehicle.
