FORD 2008 F-550 v.3 - Manual (Page 370)

BRAKE FLUID
• Vacuum boost system
• Hydroboost system
The fluid level will drop slowly as the brakes wear, and will rise when the
brake components are replaced. Fluid levels between the “MIN” and
“MAX” lines are within the normal operating range; there is no need to
add fluid. If the fluid levels are outside of the normal operating range the
performance of your brake system could be compromised; seek service
from your authorized dealer immediately.
CLUTCH FLUID (IF EQUIPPED)
Check the clutch fluid level. Refer to the scheduled maintenance
information for the service interval schedules.
Use only a DOT 3 brake fluid designed to meet Ford specifications. Refer
to Maintenance product specifications and capacities in this chapter.
