Guys i need your help bad, I just finished a five lug conversion which went smoothly, and i also upgraded my front calipers to 300zx TT 30mm aluminium calipers. When i went to go bleed the lines everything went smoothly i freed them of bubbles and did exactly what im supposed to do. Then i found out that the bottle was labeled synthetic and a guy from autozone told me i cant use that, so i drained my lines and got some regular brake fluid. I pumped the new brake fluid through the drained lines and through the calipers, i even bled the MC. Now all that happend weds...it is now friday and i am stillllll bleeding the lines and getting no resistance on my pedal. So someone please help me because i am at the point where i dont know what to do next. Can i even still use my s14 MC with the new calipers, someone that did the conversion told me i could and that the 300zx MC is just for better performance. I am almost positive the rear rotors work because ill start the car put it in 1st and get the wheels spinnin and then step on the brake pedal, (gettin very little resistance) and i will stall the car out. So please let me know what to do i am stuck right now and dont know what to do.

Try bleeding the master at its lines.
