10.  Release the vacuum in the Vacuum 

Pump with the Vacuum Release Valve.  
Then, disconnect the Brake Bleed 
Screw Adapter from the vehicle’s 
brake caliper bleed screw.

Note: 

 

Do not allow the Cup to fill 

completely with brake fluid.  Keep the Cup 
as level as possible during use and do not 
allow fluid to reach the Suction Lid at the 
top of the Cup.  When necessary, release 
the vacuum in the tool and empty the Cup 
of old brake fluid.  To assist in transport, 
this set includes a Transport Lid (2b) 
without hose connections.  
After the brake fluid is disposed of 
properly, resume bleeding the brakes.

11.  Remove the cap from the vehicle’s 

master cylinder, and refill the master 
cylinder back to its normal capacity 
with clean, new brake fluid.  Then, 
replace the cap on the master cylinder.

12.  Proceed to the vehicle’s next 

brake caliper, and perform the 
same steps as above.

13.  When finished using the Vacuum Pump, 

clean the tool and store it in a clean, 
dry location out of reach of children.

14. 

WARNING!  TO PREVENT SERIOUS 
INJURY:  Before driving the vehicle, 
carefully check for leaks and test 
for proper brake operation.
