TR6 76 TR6 New Brake Bleeding

[Don_Houston]

All new brakes and lines installed all around. New servo and master. Lines were tested from the master cylinder and pushed fluid out of all bleeders. After coupling the lines to the master I can't get any fluid pushed out to the bleeders. You can see it pushing air, but no fluid. I have opened all bleeders and tried with just one open. I removed the master and manually pumped it and it does push fluid (and servo operation looks ok).

What am I missing? Many thanks!

I don't understand the part about having all the bleeders open... you mean at once ?If that's so then that's why you keep sucking in and pushing out air.
One at a time starting at the right rear, then left rear , right front , left front ..one at a time.

It's a 2 person job. Station one at the bleeder for the longest brake line. Station another in the cockpit. Pump the pedal a few times, have the brakeman hold the pedal down, and open the bleeder. When the pedal bottoms, have the brakeman say so, close the bleeder and tell the brakeman to pump again. Repeat til no air comes out when you crack the bleeder. Move to the next longest line and do it again. And so on. After all 4 are finished, do all 4 again. Don't let the res run out of fluid.

Especially the low volumn portion in the front of the reservoir. It holds fluid for the rear brakes and empties pretty quickly during the bleeding process.

Thanks to all. The main problem was the upper portion of the new master cylinder which was air locked and would not push anything to the front brakes following your suggestions and other standard bleeding procedures. Thanks!
