master cylinder???

[lucifer]

Need some help with master cylinder selection.
I have installed four wheel disc brakes and I am not sure whick master cylinder and booster I should use. Please don't direct me to CPP. I just finshed installing a bunch of stuff from them that all needed modification to make it work.
If anyone knows the application I need I would really appreciate it.


Thanx

Don’t know what year truck you have, but you might want to check out the Master Power Brakes web site, at least to help identify the part numbers or applications that would provide the master cylinder you need:

Captainfab also sells booster brackets if you’d prefer to source your own booster and master separately from a kit:

I had good luck with Inline Tube http://www.inlinetube.com/ When I put power discs on my Chevelle.
I used CPP for the rotors and calipers on the 64 C-10 and had no problems there.
Master Power Brakes is also a good choice I am told.
Watch some of the aftermarket kits as they are metric and have smaller rotors (S-10 and others)
I think about any GM or aftermarket (wildwood , etc) will work, Just depends on the space available for your booster. Bigger boosters have more PSI assist. (Remember power boosters need at least 18 " HG Vacuum at idle to work properly)
You will need at least 1 1/8 bore in the master with power assist .A non power bore is closer to 7/8" or 1".
Remember to use the lower hole on your brake pedal for the pushrod or Drill one lower to increase leverage
I am using a 75 GM Impala booster and master for my Disc/drum set-up

You know that is the way things usually go on old truck projects, Everything needs tweaked slightly.

I added disc brakes on my 64 and used a 70 corvette manual disc brake master and I've had no problems. Bolted up with no mods to pin. And no booster of course.

If by chance your engine doesn't make enough vacuum to properly operate a vacuum booster, you might consider going with a hydroboost setup. I have the parts to make that work as well.

As for the master cylinder, most guys with 4 wheel disc's go with the Corvette master. A lot of newer cars and trucks have 4 wheel disc's, but those masters are typically aluminum bodies with plastic reserviors.

Thanks Captfab. Looks like the Corvette master wins! I only want to do this once so all the help you offer is great.
