Best method of bleeding MC under floor

Finished the brake job on my 34' Ford Coupe. New Mustang II 9" rotors/calipers/pads and rubber hoses. New MC 1" bore/Control Valve/2# Residual valves...Front/10# Residual valve rear and Rubber hose over rear axle.

It has a 7" booster and MC mounted under the floor. Can't seem to get all the air out of the system. Tried Mighty Vac and the old way of pedal pumping with assistant as I opened and closed individual bleeders.

How can I be sure all the air is out of the system? I've got good brakes but seems to me that they should be better. Pedal goes down quite far but not to the floor.

Should this 2700# car be able to lock up the brakes at 50 mph. on a black top road? It will lock up all four on a gravel road.

Any and all thoughts are appreciated!!!!

Have you done a bleed hob on the mC itself? loosen the fittings on the MC and alternately loosen-pump-tighten.

I have l almost the same setup you have on my 34, Willwood calipers all the way around, with a Corvette manual MC. I haven't driven the car yet, but the brakes feel quite capable.

Bleeding MC

Yes............The MC was bled with no air present after thorough bleeding. I'm just wondering what is the best way to get all air out of system with MC below the floor. Mighty Vac/Pressure Bleed or old fashioned way of pumping and closing bleeder.

i'd go with a pressure bleed. that MC is pretty low, and pressure may be the only way to force the air to the bleeders...

This is how I did it on my 1930 Model A with a similar set up as you have. Go to the parts store and get the one man bleed kit for about $7.00. Its a small bottle with clear tubing. The key is to place the bottle up higher than the caliper. I use a jack stand to mount the bottle to. Open the bleeder valve about an eight turn and pump the pedal up and down making sure your master cylinder does not run out of fluid. You do not have to close the bleeder valve each time you let up on the pedal. When you see no bubbles in the clear bleeder hose your done. Usually quicker if you start with the longest brake line and work to the shortest. This method has never failed me.
