Contact Jay over at Mustang Depot, he is the owner and posts here often. He has the dual MC setup and is planning on taking it off. Refreshing (in my opinion) to find a vendor who is candid about the parts the aftermarket guys are hawking, and Jay certainly qualifies.
If you're going 4x disc, use an MC for an 85 Continental w/ Hydroboost..identical to the elusive SVO aluminum MC, looks stock and doesn't cost a fortune like the JMC setup (but you lose the major cool factor!)
I'd bet that's just a Baer 13" kit that JMC is selling anyway. I'd look into the Baer 13" kits and the MustangSteve Cobra kit.

I am switching to a hydro boost myself and will be selling the JMC Dual Res Set-Up. No hurry though...
The JMC kits are not the Baer Systems. It's a pretty nice kit but kinda spendy.

I'm switching it because I need a power brake set-up. I have a very quick car that needs to be just as responsive to stop.
The manual set-ups require too much foot/time to push it down and I don't have that time with this car. Plus I'm getting old, lazy and weak

here is apic of an SVO unit.
$24 at local parts store w/ $10 core charge not bad.
I also have a non-power 4 disc setup

Could possibly clarify this a little bit? What is your opinion of the JMC unit? As compared to a regular dual master cylinder (manual of course) or a normal power booster set up.
thanks..

It's a hard pedal. About the same or maybe a little harder than the regular manual units. I had the SSBC dual bowl pwr set-up before I went to the TKO III and the hydraulic clutch. So it had to come out.

Okay.. I'm trying to get educated here I guess. The pedal pressure I have in there now is hard. I understand that the power booster gives you braking power with less pedal effort. But does it actually help ultimately clamp the brakes harder? I mean... it's all about fluid pressure, right? So why would the JMC master cylinder clamp any better than a typical dual bowl master cylinder if it's not power assisted? Is there something I'm missing here? I don't care how hard I have to push the brake pedal... I just want optimum caliper clamping force on my rotors.... does that make sense?? Does the bore size off the MC effect anything?
I'll give this a shot: the function of the booster isn't so much to make the calipers clamp harder than it just makes for less effort to get on the brakes REALLY HARD.
You could brake the same way in a PB car as a MB car, but with manual brakes, you'll have to do your best to instantaneously shove your foot through the floor to get the same effect as mashing the pedal on a PB car.
I guess the best way to sum it up would be that with power brakes, you get more for your money -- more braking force for a given amount of leg pressure. There is a point when the calipers have clamped all they're going to clamp; a booster, or anything else shouldn't effect it that much; as to giving BETTER clamping, assuming the existing system does the job.

The two biggest arguments for using the JMC (in my opinion) is that they look great and you don't have to use a proportioning valve for bias.CornerCarvin67 said:
A power booster does not increase the braking power of your car assuming you are in position and have the strength to mash the brake pedal really HARD, it decreses pedal effort only.
Bore size has more to do with how much fluid gets moved than pedal effort, which size to use depends on the fluid capacity of your calipers. Small capacity calipers with a large bore MC will not necessarilly increase pedal effort but it will decrease pedal movement, short movement makes modulation more difficult.
