Looking at Pressure brake bleeders. I have only used the commercial model back when we had a service station that had a bladder so no air would touch the brake fluid.

Are they any issues with the Motive stye that uses air pressure?

 

All right LOL no one is using any break bleeders?

 

Im old school.
Pump it up!
Holding!
Pump it up!
Holding!
Are we done yet!

 

I would like to do it that way except I have to many cars to change the brake fluid in. Also it takes a helper that will not lift off the pedal LOL
