Ok I realize that this question must have come up before,but here it goes again. what is the difference between bench bleeding and bleeding the master cylinder after it is mounted on the firewall before the brake lines are installed into the master cylinder?It would seem easier to do it on the car. I am installing chrome a chrome master cylinder with a 9" power booster. Thanks ahead of time for any input, Tony's Last Toy :gba: :shakehands: ps: I finished installing my race deck floor in my garage it took a full day it was easy looks good and it is nice on the legs not having to stand on the concrete any more.

I understand the the pedal push rod may not push the M/C piston all the way to the bottom of the bore, leaving some trapped air in the M/C. By bench bleeding, you can push the piston all the way in.

Plus you can bleed it and very easily keep an eye on the tubes watching for air in them while pushing the piston in.
