Brake line pressures

You're correct that you only use half the number of pistons for the effective area calculation when looking at a fixed mount caliper. I know that it is counterintuitive, but just go with it. As for the master cylinder, no more bubbles doesn't necessarily mean no more air inside...just no more air coming out. I always plug both outlet ports and push on the piston to confirm that there is no more air hiding in the MC. A fully bleed MC will hydraulically lock after about 1/8" of piston travel, just enough for the seals to clear the compensator ports to the reservoirs.

Thanks again Tobin. So how would you get more air out if you've bench bled and pressure bled already?

I might get some plugs and give it a try. I still think it is a MC issue either a bad one or air in there. With air I would expect the pressure reading to be all over the place and not as consistent.

"You're correct that you only use half the number of pistons for the effective area calculation when looking at a fixed mount caliper." Seems then like a fixed caliper shouldn't work as well as floating then to cram pistons in.

Here are the Wilwood dual piston calipers that would swap on the rear. Might have to look at the dual 1.12 ones. But heck that is almost 3/4 the price of a Dynalite rear set up, but I'd have to pull the axles out to get the caliper bracket off.
