Bench Bleeding MC ?
I was bench bleeding the master cylinder with the tube kit that came with it. I pushed the cylinder in and out until there were no bubbles. After that I pushed it a few more times and notice that good bit of fluid move in the front but I could not see the level change in the back. Would that be normal? No more bubbles came out..
Thanks Louie

If you are not getting fluid from BOTH it is abnormal....I got this from the guy at Cardone when I asked the same question...

No it is not. You should be pushing fluid through both ports. This unit has
an internal problem and needs to be replaced.

Re: Bench Bleeding MC ? (Yanni88)
Yanni88 hit the nail right on the spot. If you have only one port giving pressure, you have a problem with the bias spring. IF you disasembeld the mc , then you need to go back in and properly set the spring and piston. Both ports should be giving even pressure. I always bench bleed the mc after mounting it on the car. It makes it easier this way.
Good Luck! :seeya

Re: Bench Bleeding MC ? (Louis J Hoppmann)
Thanks for the help. After I did the bench bleed I got out the manual. The manual has procedures for bleeding on the car. So I did it again that way. I did the front about 5 times before all the air was out. I had to do the back one about 15 times before all the air was out. With the unit on the car and the front system closed the back system had a good fluid flow. This unit is a rebuilt one I got from the parts store and I did not open it up. After bleeding all 4 wheels the brakes are good. I wish when I bench bleed it I would have closed the front and then checked the back.
Thanks Louie
