I think you might be on to something regarding my pedal not pushing completely into the MC. When I was bench bleeding the MC, at the end it got to the point where I could barely push the piston in, so I figured it was fully bled. I would assume if the booster rod was pushing into the MC I would encounter that same resistance, but like I sad it goes right to the floor very easily. I'm gonna call Early Classics as well to see if they know anything about a spacer. Like I said I'm pretty sure the piston I was pushing against was flat with no shape at all, but to bleed it I did have to stick a phillips in to the MC about 1" to contact the piston.

One question. When the motor is running the pedal goes to the floor very easily, but when I turn off the motor there is a bit more resistance in the pedal. Any reason for that?

Also this is a dual MC kit with dual front lines and proportioning valve. There is a thick (rear) line and a thin (front) line coming of the PV. Thick line goes to the rear and thin line breaks off to the calipers. Doesn't seem to be any leaks and I did bleed all wheels after I hooked up the MC.

Thanks!

((One question. When the motor is running the pedal goes to the floor very easily, but when I turn off the motor there is a bit more resistance in the pedal.

I still think the little spacer is going to be the solution. I read about some 'Corvette-style' mc's last nite, & the site mentioned it included an 'adapter' for the different style mc.

This site mentions the different mc's, the deep-hole and the shallow-hole. Don't see the site mentioning including the adapter right now(gotta go meet my walking buddies).
