85 W123 Brake Bleed Coming Up

[rmmagow]

I need to bleed my brakes and want to follow Army's recommendation about bleeding with the engine running. Do I have the second person pump on the brake pedal, hold hard, then I open the bleeder and watch for all bubbles to stop? Do this on all 4, watching closely the fluid level in the reservoir. I plan to put a block of wood under the brake pedal and bleed in the proper sequence. Rear brakes were recently completed, new calipers and rotors. Fronts are OK and bleeders are not seized. My problem is a low pedal and excessive effort to stop the car compared to how it was before.
I used a Motive Bleeder before and bled the brakes by myself and am thinking the pump-the-pedal method may be required for this car.
Last warm day in the US NE is Sunday :-(
