I have a 58-54 set up that I will be replacing the master cylinder and new pads and hardware I the rear. I'm a little confused as to the right way to do this. First thing is how should I bleed a single stage master cylinder? I've heard a few ways but they all seem to be different.
Then the next thing is once the master cylinder is bleed how do I go about putting fluid into the line? I'll have the 3 lines hooked up to the master cylinder. Do I just pour fluid into the resivoir till it fills the lines up? It seems like that would push air into the ends of all the lines. |

Bleeding a single circuit is the saame as a dual. Always start with the farthest corner, and work toward the master cyl. To get the fluid in the line, you fill the reservoir. Then you "Bleed" the lines, by pushing the fluid thru and the air out. Air int he line = a spongy pedal and a poor braking situation. You're aiming for a rock hard pedal. Bleeding is usually a two man job, one pumping the brakes and keeping the res. full, the other at the wheels being bled. If you let the res. get low enough to suck air, you get to start over...... Have fun.

I should bleed the master cylinder first before I connect it to the lines?
I know the process the bleed brakes once all the fluid is there is putting the fluid into the lines that I don't under stand. When I pour it into the resivoir do I open all the bleed ports on the drums so push the air out of the lines as I fill the lines? |

Bleeding the m/c prior to install is what we call bench bleeding. It's a personal preference IMO.
Some guys will fill the res. and open the bleeders and let it gravity bleed over night. THe std. method is to pump the pedal............this pushes the fluid in, air out as I stated above.

What is the way to bench bleed the single stage master cylinder?
I think we are getting confused. I mean filling the lines before I start bleeding them. I just pour fluid in and start bleeding that it or what? |

Don't worry about bench bleeding..............just fill the res. and pump it thru. Are we going in circles here?
