Your Master Cylinder/Booster selection
« on: March 28, 2015, 07:17:35 PM »
Wanted to use the master cylinder and booster from the 95 Z28 I parted for the driveline...but it's huge...want are you guys using? 

The unit will be firewall mounted and with 4 wheel disc brakes.

Thanks

I usually go with a dual diaphram 7 inch booster and a corvette style  master cylinder. I have gotten most of the units I use through Gear head industries. They seem to get a bad rap, but I have never had a problem, and the pricing is right.

I used the same type as Ghost.  I bought it from my buddy at New England Rod Shop.  I did mount mine under the floor though.  I like it so far.

like the prior two posters said use the 7" dual diaphragm with disc disc POWER master.  Also use the correct gm proportioning valve for disc disc over the wilwood adjustable .  Factory one is superior.    Seeing as how you will be firewall mounting it,  no need for residual check valves

Now you may also want to consider IF you have enough engine vacuum as power boosters require 18---21"  to operate correctly.     I had to buy a stainless steel brakes electric vacuum pump , around $300, because my camshaft only produced 13" of vacuum.   The difference to the stopping power was nite and day !!!!!!!!!!!!

I used the early Corvette style master cylinder as well but I didn't want the booster on the firewall plus my cam was too hot to allow the engine to produce enough vacuum so I opted to use a hydorboost system that runs off the power steering pump. Having worked with GM I had a lot of experience with the system that was first introduced on the diesel Cadillac Eldo's and Sevilles in the 80's and is still used on the diesel trucks because the diesel engines don't produce vacuum. I used the early system instead of the truck unit because it is much smaller than the later units because it uses a spring system to maintain residual pressure rather that a gas filled calendar that the later units use. If the engine dies or something fails in the pump system I still get 3 pumps of the brakes with power assist before the system goes to totally manual brakes which is no big deal. The unit was mounted under the floor and because of it's size fit with no problem plus because it uses pressure from the steering pump it has much more boost exponential than the vacuum system which results in a much better braking system. It is not overly sensitive on initial pedal application but really gets the job done on hard stops. After using it on the 32 I'm spoiled by how well it performs over the vacuum system and would highly recommend the system. Because most people aren't too familiar with the system they shy away form it and believe that its too completed and failure prone but my experience with the Cadillac and truck systems has been just the opposite....It's a great system.

  Well i am like MOOSE and using very simillar equipment as most dual system and i dont have it on the firwall I have it in the trunk with a hydralic slave cylinder operating the brake system I will look around and see if i can not get you guys a picture of how this works. It is like a slave unit pushing a clutch only the line is long and it goes to a rod on the end of the booster and drives the brakes  simple actually and no clutter on the firewall OH and i am running drums/drums so have residual pressure all the time  vette59jdwl
  Ps  I do not drive this behond higway speeds its still only a plain jane six cylinder engine

That's what I have on my 33 Chevy, on my 34 Chevy looks like a stock Nova setup.

I heard of guys using Ford LTD boosters...but a new dual diaphragm booster is cheap enough in 7" or 8".  I may just buy a new booster and use one of my oem Camaro master cylinders. The LT1 engine is stock so it will have plenty of vacuum.

Took a steering column out of a 1990 Camaro, stripped it down, made mounting hardware and installed it in the 37 Chevy sedan today...fit nicely and even used the original hole in the floor.

On my 38 I don't have a booster but in the process of adding it along with the larger rotors. On  my 32 I using one I purchased from gearhead as the price was very competitive hope it does well

I'm just using the vette(C3) master, no booster. When I had my pair of '69s, my coupe had power and the convertable didn't.  I think the cam may have hindered the power brakes on the coupe. ::)The manual brake one had an easier pedal, so i hope my '35 will work the same.  :)

In corvette master cylinders there are master cylinders for power brakes and master cylinders for NON power brakes.  Preferably 1 1/8" bore on the master is the one to use.

There are GM combination proportioning valves for disc--disc brakes and valves for disc--- drum combos.

  4 wheel disc brakes use 3/16 " lines.
 
  Disc front uses 3/16" lines and drum rears use 1/4" lines .

Wow, I feel like a caveman. I got a bare bones dual resevoir cylinder from Speedway, manual,  no power. That's it. I do have front disc at least :)
Tighten it up til it strips, then back it off a quarter turn

Nothing fancy, I believe I just used 3/16" steel line. The rear is out of a '57 Chevy so the brakes are '57 Chevy drum. Car seams to stop with no problems. They are not too touchy and I don't have to stand on them either.

just make sure that if your going to firewall mount it, that it clears the valve covers.
