dual master cylinders. school me.

What are you guys using who have upgraded? I seen one awhile ago with a remote reservoir that seemed sweet that could be filled up from the doghouse but can't recall who made it. I'm looking to buy a brand new one and I don't want to monkey around with the later model dual one from later years. I've got a mustang II front clip on the way with disc brakes. What's my best options and why? Thanks.

I’ve used the D&D set-up (I think it used a Ranger master cylinder), as well as the Modern Form set-up which uses a Wilwood master with remote reservoirs. Both get the job done, but both are manual systems that take a REALLY annoying amount of pedal pressure. I’m getting ready to rip mine out and go with a 55-59 Chevy frame mount booster with a Corvette master. You can get a remote reservoir kit for the Chevy master, and the install is straightforward, especially if you’re putting in a new sub. Several guys have already done the conversion, and if you do a search you’ll see some good photos of how they did it. The only way I’d recommend any of the manual systems is if you’re planning on a radical cam profile and don’t have the vacuum available – but even then, I’d spend the $$$ for an electrically boosted system.

An electrically boosted dual master cylinder. I haven't stumbled across one in my searching. Any source?

87-88 Turbocoupe, but you have to gut the ABS. I have them if anyone wants to come to NC. and take them out. They are a PITA to remove.

Price is pretty brutal, but here 'ya go...

Brutal is right. That's the price I just paid for my entirae mustang II clip with a rack, bags, disc brakes, and tubular arms! Maybe I will just go the wilwood remote route.

Brutal indeed! For that price you could get personal trainer to buildup your leg muscles to use the manual brakes.

why dont you just adapt the 55 - 59 chevy truck kit like it did? its obvious you have the fab skills. that 7inch dual booster works great with my mustang II brakes and stock drums

Sure....I just don't know anything about it. I will look into it. I am just coulees about it all. I don't even know wtf a 7 inch dual booster is! Haha.

They are making a new GM style caliper that requires less pedal presure than stock GM calipers. I think it's SSB that's selling them. Of course special means more money.

Duane in Tennessee.

Along with my disc brake setup I also sell re-sleeved and rebuilt 67 master cylinders. I also, make a remote reservoir kit for them.
BY FAR the easiest is the 67 bolt in,,, done deal. Convert your early push rod and use an adjustable brake light switch the same as D&D does... simple...
Far as power brakes go use the hydro vac setup its also the easiest. Uses the power steering pump for it to work and is the smallest unit. SEVERAL done already,,

Great info here. I would like to add disk brakes with the dual master as well. You may want to consider just manual brakes for the simplicity though. I removed the power brakes from my 66 fury and went with manual so I had brakes all the time. Not just when the car was running. I went with a 1" bore rather than the larger 1 1/4, as  it  requires less pedal pressure to stop. I could see wanting power with drums. but with disk. there real is no need.
Just my 02 though

Thank you,,,, I work hard at it,,,

Just my O2,,,,, For years now have been talking to many of the tech people in regards to their brake kits,, and, of course disc brakes being the catalyst..... SERIOUSLY got into pressure multiplication, theorys and during the disxussions the masterf cylinder bore size at the heart of it all.
The manufacturers realized that with a smaller bore size and less effort required to engage power brakes that it actually made the chance of locking up the wheels far too easy. SO,, in most all power brake applications you will find a larger master cylinder bore size on purpose.... When I had been talking to the last techs about it in ours, using my AMC conversion Wilwood had advised using a 1 1/8" bores size.
In the not too far distant past,, LOL..... there was a pretty good thread in that the person was trying to play with wheel cylinder sizes and thought that he could improve on the present brake bias setup...
That person TRYING to use a Ranger 15/16th master cylinder bore size master cylinder in order to create his own cheaper version of power brakes. He did not take into account that by increasing the pressure multiplication which was the main intent, he forgot to also figure in the LOSS of total volume that he created and not having enough brake pedal left to even come close to fully engaging the brakes.

He HAD increased the pressure, but at the loss of pedal travel and could NOT STOP....

I have been advising people to buy and read a very valuable book now for many years. It IS an excellent source of good information and fully explains brake pressure multiplication, brake pedal travel, dual cylinder, rotors and even talks about drum brakes and how they actually are a cheap mechanical power brake by simple operation.... Residual valves, proportioning valves, and brake bias.
ALSO,,,,,,,,,,, DETAILED information about how to setup all kinds of suspensions. From trac bars to bump steer, how to bend a steering arm and make your own bump steer gauge. An invaluable research and study guide,,, WELL worth the price....

Damn Vic you are a fountain of knowledge wish I could sit and shoot the bull with you for about a week lol!!

I have the brakes on my 65 that it came with, I have heard the brakes suck - but mine actually seem to work fine. What I am wondering about though is there a power steering box that will fit in an E truck? Dont want to do the rack and pinion thing.... but if there was a box that would bolt in with no or few modifications I might do that.

I will definitely look into getting the book.I have a friend that runs 4 wheel manual disk as well on a mopar. maybe we got lucky? I will see about getting the book though. I am always up for learning more  

I have done two power steering setups using the Toyota box. There is NO bolt in or easy way to do it,,,,,
Vic

Which toyota box did you use Vic?
