Well I know that's not the problem because I just bled the front master cylinder by using the plastic fitting with hose. I actually saw bubbles as my helper depressed the pedal. Yoou know what I mean where you take the hose and submerge it in the fluid. Same thing as bench bleeding but did it on the car.
Yes, I understand. If the MC is producing the required pressure then you should have pressurized fluid flow when you open the bleeders with helper pushing pedal. Either the MC is not producing the pressure or you have an obstruction. You should not be able to hold back the pressure from the MC while holding your thumb over the outlet hole with helper pushing on pedal. Sorry I can not offer more help. Frustrating when I can not get my hands on the car. mike...
Your master is probably bad, doesn't matter if it's new.
If you get flow with the Motive then the system is clear and full, including the differential valve, hoses, and the master pistons are relaxed.
You're simply not pressurizing the front circuit.
Probably nothing wrong with your calipers, talk to another shop.
My thoughts exactly. As soon as OP said he couldn't get fluid out of the front calipers when manually bleeding (but could with power bleeder) it sure says bad M/C.

Well I just went out to the car and gravity bled the calipers but just for a short time. At first I didn't have any fluid coming from the LF caliper then it started to flow. After awhile I closed the bleeder up and checked brake feel. Nice and firm so now for a test drive. I now have a firm pedal but it seems too firm if that's possible. I tried to lock up the tires but it wouldn't do it, I did this at different speeds. I don't know if this is correct or not. I did however order me the correct M/C, new bleeders and a set of stainless steel brake lines. The only way I was able to lock up the tires was in gravel and that was at low speeds but the back wouldn't lock up??
