hose from bleeder to bleeder in the proper sequence.
8. When finished, turn the “Pressure” switch and the “Vacuum” switch to the OFF position. The pressure
will automatically relieve from the new fluid hose. When the pressure on the gauge reaches 0 psi
disconnect the new fluid hose from the master cylinder adapter. Adjust the fluid level using adapters in
either vacuum or pressure hoses as required.
9. Remove master cylinder adapter.
10. Reinstall the original master cylinder cover.
11. Empty the waste capture tank into a recycle container.
12. Empty the new fluid back to a sealed new brake fluid container to keep it dry and ready for the next
vehicle service
Note: If the Pressure Bleeder does not operate when the switch is in the ON position, check the circuit
breaker mounted in the front of the unit. Replace if necessary or contact your MotorVac BRAKEVAC-II
service center.
Brake Flush Service Procedure (Cont’d)
Adjusting the pressure regulator
The pump has a preset pressure of 45 PSI/ or 3 bar by the manufacturer. In some cases the recommended
procedure may call for a lower pressure. Release the locking knob by pulling outward then turn the knob
counter-clockwise to open the regulator to the lowest pressure setting. Then turn on the ‘Pressure’ pump
and turn the regulator knob in clockwise (when starting from 0 PSI on the pressure gauge) until the proper
pressure is reached.
Automatic low fluid level warning system and shut off
The MotorVac BRAKEVAC-II will shut off the clean fluid pump automatically when the fluid level in the tank
reaches 0.8 liters. This ensures that no air will be injected into the brake system. The low level warning
light will illuminate alerting you to the low level condition. Remove the fill cap and add fluid and replace cap.
Continue bleeding where you left off.
Emptying the tank after each use
Use the Pressure hose and attach an adapter that will allow brake fluid to be drained into a container. Place
the adapter in a fashion that will allow the brake fluid to drain into a clean capture tank or bottle.
Turn on the “Pressure” switch to drain the brake fluid. Brake fluid will start to flow immediately when the
“Pressure” switch is turned to the ON position. The tank level switch will turn off the flow when the brake fluid
tank is almost empty. To drain the remainder of the brake fluid from the tank and hose, press and hold the
“Drain Tank” switch until the brake fluid tank and hose is completely empty. Release the “Drain Tank” switch
and turn off the “Pressure” switch.
After filling the tank with new fluid, attach any adapter to the black hose coupler and direct the fluid flow to a
capture container. Turn on the “Pressure” switch to bleed all the air out of the black hose prior to beginning a
new service.
The unit is now ready for the next service.
