about 7 repetitions, the pedal went all the way to the floor before opening the port each time - but fluid still came out when opening the port, just not much. no more bubbles from the 4th time to the 7th so we moved to the left rear - -same thing - the pedal went all the way to the floor before opening the port, but fluid still came out and there were bubbles the first 2 or 3 tries, but not the last 4 or 5. did all 4 the same way, still all the way to the floor. |

You'll want to bleed them with the engine off. How have you been doing it? Doc |

7 reps...took me about 40 reps to get the all of the air out starting from the the passenger rear when i replaced my master (bled it the old fashioned 2 man way that doc described)...the solid stream of brake fluid could be the old fluid still in the brake line with the residual air from the master still traveling through the lines (as i experienced)...i was going to give up after the 20th push but continued on and it eventually blew out more air...used half a quart of fluid)...top shape after... |
though, he's the one on the ground... ;-)

the master cyl FIRST, after a m/c replacement. Then bleed at the wheels to
flush the old fluid (and contaminates) out of the system.

Then bleed at the wheels to flush the old fluid (and contaminates) out of the system. H |
beside the master cylinder before installing it. Not every time but about
50% of the time all of the air is gone when bleed at the master cylinder
lines.
