[DML] "Bench Bleeding"

["Ed B." <mr.pants@xxxxxxxxxxxx>]

Hello everyone & Happy New Year to y'all from the Great White North...!

I,too, have less than stellar braking since I replaced my master 
cylinder, rotors, pads & callipers.  So bad, in fact, that with the car 
up on jack stands and the engine & tranny in 1st gear idling (no 
accelerator applied), all my weight on the brake pedal will just barely 
stop the rear rotors from turning.  Fronts seem OK & I can stop the car, 
however the stopping power/distance is not great & I'm feeling that most 
of my braking power is coming from the front.  When the car is on the 
road, I also have to press the brake once before the pressure seems 
right to stop the car.

I've bled many a brake system on many a car, and the DeLorean is 
certainly nothing complex, yet I don't know what I've done wrong.  I 
read here recently about "bench-bleeding" the M.Cylinder...  can this be 
done on the car?  i.e.: can I just disconnect the brake lines, connect 
two short tubes to the m.c. outlet nipples & bend them 'round back into 
the reservoir and have somebody pump the pedal?  Or does it need to be 
done outside of the car?  I am hoping that after I do this, my braking 
will be back to normal...
