Extracting Brake Fluid from the Master Cylinder
1. Clean the exterior of the master cylinder and master cylinder cap. (This will prevent dirt from entering the
master cylinder reservoir when the cap is removed.)
2. Remove the lid of the master cylinder reservoir.
3. Select the appropriate “dipstick” tube and connect it to the main suction tube.
4. Insert the opposite end of the main suction tube into the top of the reservoir tank.
5. Insert the end of the extraction tube into the master cylinder reservoir.
6. Connect air hose to the venturi at the base of the PneumatiVac. This will require a male 1/4" NPT
fitting (not included).
7. Open the air valve thereby creating a vacuum inside the reservoir tank that will be used to extract the
fluids.
6. Once the break fluid has been extracted, remove the main suction tube from the reservoir tank; pour
the break fluid from the tank into a suitable container, and dispose of it in an appropriate manner. Rinse
out the reservoir tank with clean solvent or engine degreaser. Allow it to dry thoroughly.
7. After all repairs are accomplished, refill the system with new, manufacturer approved brake fluid from
a sealed container.
Prior to inserting the extraction tube into the master cylinder reservoir, be sure that the
extraction tube is clean and free of any other types of fluid. Failure to do so would result
in contamination of the brake fluid in the hydraulic system and cause potential brake
failure.
MAXIMUM TEMPERATURE OF FLUIDS: 176° Fahrenheit, 80° Celsius
6. Open the air valve thereby creating a vacuum inside the reservoir tank that will be used to extract the
fluids.
7. Once the desired amount of fluid has been extracted, close the air control valve to stop the extraction
process.
8. Remove the main suction tube from the reservoir tank; pour the fluid from the tank into a suitable
container, and dispose of the fluid in an appropriate manner. Rinse out the reservoir tank with clean
solvent or engine degreaser. Allow it to dry thoroughly.
9. Refill the system to the desired level.
10. Run the engine until it reaches operating temperature to circulate the new fluid and then re-check the
level to ensure that it is full.
