wow, lost of writing since I last looked... …as far as the pissing contest, I don’t care. Everyone communicates different, some are better then others.

well,
The calipers are the same BMW E-36 M3, visual inspection they are installed the same and appear to be in good working order (no leaks, look symmetrical to each other).
Pads were replaced with Repco semi-metallic to minimize brake dust. Visual inspection they are wearing the same. The pads that were removed also looked to be wearing the same.
The BMW E-36 M3 front rotors (315mm X 28mm (12.4")) are the same and show no signs of overheating, warping, or inconsistent wear.
Front tires are the same brand, type, size, and have the same treadwear.
The flexible brake lines from the hard lines are stainless steel replacing the stock rubber lines.
The car was aligned and balanced at the same time. I did not ask what the value for each corner was or even the spread, I should have. I also don't know if there was dummy weight added for the driver. I am now living 3000 miles from that shop.
The vacuum is in the mid 20's and drops to about 0 depending on if the engine is under load. I can feel the brake booster "function" when the car is started, as in feel it in the brake pedal.
The car has always had this problem since day one independent of any of the changes made including: springs, pads, brake lines, alignment, balancing and brake fluid.
As of today, I have been unable to determine the pressure at the calipers due to the fact that today is monday and most buy-on-line places don't ship on sundays. When I do receive the two pressure gauges I will test both sides at the same time with the car running and off, to ensure the brake booster is function correctly and the pressures are the same.

I purchase the car as a new roller and installed the rest myself (not hard to do).

I am pretty knowledgeable in how my vehicle works and a number of other things: physics, fluid dynamics, structures, aerodynamics, and arrogance to name a few. How brakes function is a simple concept, even anti-lock systems. And I personally like the fronts to lock up before the rears so the rear doesn’t become the front under corner braking.

I will try to determine the corner weights and test the caliper pressures soon.
I'm just asking for ideas to fix the problem, that I haven't already tried.

Thanks for the help,
Rob
