The following example shows how to bleed a typical vehicle break system.
You manufacture may recommend a special bleeding procedure.
Before performing any operation, check the procedure recommended by the manufacturer.
Assembling the vacuum pump.
•Connect one of the short hoses to the coupling
socket in the bottom of the plastic cap.
•Connect one of the long hoses to the appropriate
coupling socket on the upper side of the plastic
cap and place it on the collection container.
•Connect the other short hose to the remaining
coupling socket on the plastic cup (as seen on the
picture) and connect it with the pistol (hand pump).
•Place the cap on the collection container and turn it
to seal it and lock it in place.
Warning: The cup is sealed with O-ring.

Pressure equalizing screw
•The scored screw knob in the lower part of the
pump is used to equalize both pressures.
Checking the value of the created vacuum
•To check the value of the negative
pressure (vacuum) created, use the supplied
pressure gauge.
•Both scales are calibrated in mercury (Hg) column
height. The inner scale is in (mm) and the outer scale
in inches.
Bleeding the break system
•To bleed the system follow the sequence below:
•Main brake cylinder - if it is equipped with a socket for hose connection.
•Break callipers in the following order; start with the wheel closest to the main brake cylinder and move on
gradually towards the most distant wheel.
•Bleed the main brake cylinder if it is equipped with a socket for hose connection.
If you installed a new brake cylinder you must always bleed the cylinder.
•Choose the suitable hose coupling adapter and slide it into the hose.
•Place the adapter on the bleeding screw.
•Press the pump 10 - 15 times to create the necessary vacuum.
•Check the value of the vacuum on the pressure gauge.
•Turn the bleeding screw 1/4 up to 1/2 of a turn and fill about half of the container with the break fluid.
•Close the bleeding screw to close it.
•Turn the pressure equalizing screw to equalize the pressure in the system with the atmospheric pressure
outside.
•Empty the drained fluid from the container.
•Refill the engine break fluid reservoir with new break fluid, all the way to the line marked "max."
•Move on to bleed the next wheel.
•Repeat the above steps until you bleed all wheels.

After you finish your work
•Clean and flush the entire set with water, disassemble all parts and let it dry.
•Remove (unscrew) the scored screw knob for pressure equalizing and apply few drops of oil inside the hole.
Screw the knob back in and press the pump handle several times to evenly distribute the oil inside.
