Yup I am new to this board but I have been searching for 3 days for an answer to my question so out of frustration .. here goes.
I want to go to a dual master cylinder on my power brake drum/drum equipped 63 SWC. The only info I have found is that it can be done, however nobody has said how or where to get the parts. All of the single to dual conversions I have found are for converting to disk/drum or disk/disk. I don't have a problem with the drum brakes but the single MC is scary. I am old enough to have vivid memories of the brake pedal dropping to the floor at the most inconvienint of times.
So .. what MC do I need to install to get a dual MC system while retaining the original brake system?

TIA
Glenn
 
Glen welcome abourd. Allthough I dont know of a kit,and I do know that some 63 of the parts on a 63 are 63 only parts. Its not that hard to work on brakes or it tubeing.

I would think its as easey as getting a 67 master cylender and then just re piping it by just tying into the front T with a new custom line and then tying into the the rear lines with a new custom line

When I say custom just purchase some steel lines from a local auto parts store.
 
You are wasting money on this idea because a overhauled clean system with silicone fluid will probably outlast the car, my .02

Ken I think he is just looking for the peice of mind of having a daul master instead of a single,

My idea may be a problem as the drum brakes may have a problem with the master from a disk car.
 
You'll need a '67-up dual-reservoir drum/drum master cylinder (Camaro, Chevelle, etc.); they have residual pressure valves at both outlets. Disc brake masters don't have them, and you need them for a drum system.

Thanks! That was the info I was looking for. I can get a new M/C at autozone for $49.00 for a 67 Camero

I plan to replace all the lines and cylinders and use silicone DOT 5 fluid. I am considering boring the cylinders and installing bronze sleeves for that extra bit of life. (I have a lathe and mill) Silicon Bronze should outlast me in this application.

Thanks to all for the ideas and the welcome!

Sleykin,

Welcome to the :CAC

We're glad you signed up. Let me know if you need help with posting photos.

Thanks! I think I can figure out the Image posting here ... Shouldn't be too much different than the Porsche forums. I would just be seriously embarrased to post pictures of this basket case just yet :)
It has been parked in a state of "semi asembled" for over 20 years. I was able to locate all the major pieces except the engine block (has a 350 in it) It is a long story :) Hopefully I will be able to have it in "picture taking" condition within the year as I retire soon and this will be the first project on the list. The only really good thing about it is it is my wife's car so I will get lots of support when it comes to buying parts :) (her ex tore it apart and never put it back together)

Well listen I posted this photo of my vette when I purchased it and no person made fun of it, This is a real nice crowd here we are all car guys, And the majority of the member work on there own cars so youll see the tecnical advice is always available
 
Well .. at least your tires hold air :) That looks a lot like mine does now. I need to pull the body off and go over all that was done before. Little things like leaving out the body doghnuts and spliceing the metal fuel line with rubber hose .. under the body wher you can't get to it to replace it.
At least when ya start from here you can only go up :)
Thanks
Glenn ... maybe I'll take a picture when it gets light out :)

The '63-'64 Corvette drum brake cars used a 7/8" bore master cylinder. I think but not sure the Camaro/Chevelle is a 1" bore. Without the power boost that difference will give you a lot of pedal effort. With the booster, don't know. Just something to check.

JohnZ,

So the '67 Chevelle DMC (one inch bore) that I just purchased should work just fine with my drum brakes? No "hard" brake pedal?

Thanks, Cliff

If I understand all I have gathered from my research into this. If you bought the DMC for a 67 Chevelle with Drum/Drum brakes and you have power assisted brakes you should be good. The 1" MC will require more pedal effort than the 7/8" MC. The 7/8" MC will give more pedal travel all other things being equal.

You got it!.

The booster may make the effort a non-issue. If it wasn't PB's, I don't think you'd like the increase in pedal effort.
