The most critical part of the service brake system is bleeding the system. Prior
to bleeding the system, ensure all hose clamps, line connector and fittings are tight
enough to prevent air from entering the system or fluid from leaking. The
hydraulic brake system must be free of air to function properly. When bleeding,
check the fluid level in both the power steering reservoir and master cylinder. If
power steering fluid is noticed in the master cylinder, End Cap service on the
power booster assembly can correct the leak. The Hydro-Max system should be
bled prior to the brake system. Applying the brakes will cycle the pump and purge
any air from the electric pump system.
NOTE: The power steering system and the hydraulic portion of the
brake system are two separate hydraulic systems. The fluids are not
compatible and should not be mixed. Mixing of fluids will damage the
systems and reduce service life.
NOTE: Do not attempt to move the motorhome in the event any line is
disconnected, component removed or part of the hydraulic brake
system is opened. There will be no braking capabilities until the affected
system is bled.
The engine will need to be started to bleed the booster. When started, applying
the brakes two to three times will purge the air from the booster. Inspect fluid
levels and add fluid as required.
WARNING: Brake lining may contain asbestos material and should
only be serviced by qualified service technicians who are trained in the
appropriate precautionary procedures.
Bleeding the System:
It is important a supply of clean brake fluid be used during bleeding. Also,
maintain the proper fluid level in the reservoir during bleeding. The sequence for
opening the bleeder valves is curbside rear, roadside rear, curbside front and
roadside front. A clear plastic tube inserted over the bleeder valve can aide in
viewing air. Place the other end of the plastic tube in a container to catch the drain.
When the valve is opened, observe the flow of fluid. Once a steady flow of fluid is
present, close the bleeder valve. Check the fluid level in the master cylinder and
repeat the process for the remaining calipers.
Flushing the system requires that the bleeder valve be left open until the fluid
appears clear and uncontaminated. The system should be flushed whenever any
repair has been performed, ensuring clean and uncontaminated fluid in the system.
NOTE: Do not reuse brake fluid that has been drained as the fluid may
be contaminated.
