Maintenance and Specifications
BRAKE FLUID
• E-150/E-250/E-350 Single Rear
Wheel
• E-350/E-450 Dual Rear Wheel
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 the system could be compromised; seek service from
your authorized dealer immediately.
DRIVELINE UNIVERSAL JOINT AND SLIP YOKE
Your vehicle may be equipped with universal joints that require
lubrication. Refer to the scheduled maintenance information for
maintenance intervals. If the original universal joints are replaced with
universal joints equipped with grease fittings, lubrication will also be
necessary.
