Dual circuit master cylinder mounting kit 41-49 Cadillac

[Caddy Wizard]

I have manufactured some adapter kits to adapt a dual circuit master cylinder to fit on the frame in the stock location and use the stock pedal mechanism.  Uses a Wilwood dual master that works with the factory drum brakes or can be easily re-set to work with disk brakes.  Fits like a glove.  Provides peace of mind that a catastrophic brake failure won't happen to you.  Includes a powder-coated custom bracket, some hardware, and a special length push rod.  $160 including shipping in the lower 48 states.

Would it be possible to use some, or all of your kit to adapt for a 1951? Or do you know what it would take to do this type of mod on a 1951?

[Caddy Wizard]

I have done this on a 50 and the bracket had to be modified a good bit.  For 41-49, the bracket bolts directly to the frame with no problem and mounts the master very nicely.  For the 50, I had to make a substantial change in the bracket to fit to the 50 frame, which is different from the 49 frame in shape.  I am guessing that the 51 frame is very similar, if not identical, to the 50 frame in this respect.  Send me your email address and I'll send you some pictures of what I had to do to make it work on a 50.

FYI - here is Art's kit in process of being installed on my 41.  A bit easier to see now with the body off and engine out of the way!

Anyway, this is a nice kit and it installs with no issues.

I sure would like to make this mod to my '55 CDV.  Anyone done so?

[Caddy Wizard]

Dave,


Someone may have done a conversion like this, but I haven't sold my conversion bracket kit to a 54-56 owner (and haven't done this on my 56 -- haven't figured out how to do it on the 56 yet).

RPM out in California makes a kit and MP Brakes does too I think.  I went with power assist and disc as well, but I also like what I'm seeing here from Art.  The best kits (like Art's and those from the suppliers I've mentioned) require no sinificant modifications so that the original stuff can be put back on if some new buyer wants to do that.

I'm also waiting for Art to figure out how to do it on my '49 which has stick shift.  Problem is that part of the clutch linkage sits squarely in the way of the tubes that come down from the dual M/C and the bracket may also interfere.  He told me he can solve it. 

[Caddy Wizard]

My kit is completely reversible -- no modifications are made to the frame or body.  It is truly a bolt-on item and works with the stock drum brakes.

Hi Art,
I'm not normally a thinking man, but I'm thinking I need something better for my 53 S62. I had brake failure coming back from Atlanta this weekend. It was highway all the way back. Then towed to the shop. I think your bracket you used on the 50 will work for any 50-53? Yes/no? Cost for the complete kit, and what's included?
Thanks, Mike

Mike,


As stated elsewhere, I made 50 of these kits specifically for a 49 Cadillac.  Well, it turns out that 41-49 Cadillacs have the same mounting for the same master, so it works fine on 41-49 Cads.  For my 50, I had to take one of my 49 brackets and modify it heavily to fit the 50 frame (which is shaped entirely differently than the 49 frame where the master mounts up).  I have no idea about the 51-53 frames (although they use the same master as the 49, so there is good potential).  Since I don't have a 51-53 frame to work with, I'd have to copy my 50 set up and could maybe sell you one like that. 


For the 41-49 kits, I sell them for $160, which includes the custom-engineered, powder coated bracket and some special hardware (especially the custom length push rod).  The master is purchased separately for about $135.  To do this on a 50-53, I'd have to charge a pretty good premium over my standard price, since I will be destroying a perfectly good 41-49 bracket and will incur some significant expenses in revising it to fit (we hope it will fit!).  I'd have to charge about double, in order for it to be worth my while (even at that, it is more trouble to me than the price justifies).  Sorry, I wish I had a part on the shelf I could sell to you cheap and quick.  But I'd have to make a custom unit for you and there is the risk that it won't fit.  I really wish I had a 51-53 car here to do the engineering work with to make sure the modified bracket will fit correctly.


Call me to discuss.

Art are you in Atlanta area? We may be in that area for a short while around the 25th. I plan on some window work in Forsyth for about a day. Maybe?

[Caddy Wizard]

I am in one of Atlanta's northern suburbs and should be around on the 25th.  Will you have the car with you?


Art

[52Cadillac]

Yes, if all goes well Atlanta will be on our return leg of the trip. We should be leaving this Weds for Texas in the Caddy. That may be a bit pricey, but well see. Maybe we can work it out for a looksy.q. 
My mechanics theory so far is that the brake fluid may have basically evaporated because it wasn't driven a lot. I believe in more concrete evidence to come to a conclusion. I noticed no brake fluid leaking. The single master on was new when installed a few years,back? So my thinking is its the master, and a backup system would be helpful. I already have a master as an extra that came with the car. Have you ever heard of the evap theory Art?
Thanks, Mike

Mike,
      If you're coming through the Austin area give me a shout, especially if you have any car problems.  I'll be out in the shop working on the '41.  It got up over 103 here the other day so watch out for the heat.  My number is 512-626-7268.

Brake fluid doesn't evaporate much, if at all.  Probably a leak somewhere.

[52Cadillac]

Art, I'll call ya soon to discuss the bracket kit. It did have a leak Art. It was tiny, but a leak nonetheless. Alls well, but would sure appreciate backup.

Ken, I'll be in Dallas area, near McKinney on Fri for a few. I think Austin is a good piece from there? But appreciate any help I may need. If I run into any problems ill buzz ya. So far so good on the motoring. She's running excellently. A tiny bit of pwr steering fluid is leaking. Tightening her up this am. Fun as h--- to drive.

Thanks, Mike

Art,
Your kit to mount a dual circuit Master Cylinder sounds intriguing.  Now bear w/ me as I need to ask the question that nobody seems to have posed yet, namely; has anyone tried your kit on an earlier car?  Specifically, I am wondering if there is any chance it could be modified to fit a 37 LaSalle.

From Jay's post, it sounds like you have been looking into the issue of installing it on other stick shift cars.  As you know, the 37 Series 50 cars (LaSalles) were only offered as stick shift and they were also the last year that the top mount stick was used.  Mine is unaltered from the original, so yes it has clutch linkage, but at least there is no shifter linkage to deal w/ as the shifter is floor mounted.

I am not familiar with the 37 LaSalle frame, nor its master cylinder.  So I don't know if it will work or not.  My kit takes advantage of the fact that from 41-49 at least, the master was all the same and mounted the same way to the frame.  Send me some pics of your master mounted to the frame.
