Maintenance & Troubleshooting
The most critical part of maintaining the service brake system is bleeding the system. Prior to bleed-
ing the system, ensure all hose clamps, line connectors 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, a
component is 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 quali-
fied service technicians who are trained in the appropriate precautionary proce-
dures.
Bleeding the System:
A supply of clean brake fluid must 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.
