Jul 21st, 2025 | | | | Joined: Apr 2007 Posts: 10 New Guy | | New Guy Joined: Apr 2007 Posts: 10 | I am changing to a T-5 transmission, using an adapter from Buffalo Enterprises behind my 235, disc brakes on front end, and a '57 Chevy rear end. I want to keep my brake pedal in original position, but I need to change to a dual master cylinder. Does anyone know of a mounting bracket to do this? Or has anyone done this that could offer some assistance?
All help greatly appreciated.

Hard to tell what the "original position" of your brake pedal is without that. | | | | | Joined: Dec 2003 Posts: 975 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 975 | Buckeye Phil,
Most of the T-5 swaps I have read about on here all require some fabrication work for a master cylinder mount. I will see if I can come up with the posts...but do a search on T-5. Look for topics started by steppenwolf out of CA. He has some good pics of the process.

I used a dual master for a 69 mustang (drums front & rear) it works very well. I'll email you some pictures of my bracket that I fabed. (Sorry I can't post them here, long story)
Be sure and check out the links there is some great information there.

Just noticed you don't have your email in your profile. Shoot me an email and I'll get you the pictures.

Most of the MC options I find do not have clevis ends on the push rods. Speedway has universal pushrods, w/wo heim joint, but no clevis. They also have brake booster stuff for 55-57 chevy's with the clevis.
Ideas?
The pedal assemblies are forged steel - cut and weld new connection point maybe?
Cavebull | | | | | Joined: Jul 2006 Posts: 451 Shop Shark | | Shop Shark Joined: Jul 2006 Posts: 451 | Further browsing through the Speedway Cat, I found clevis, yoke, in the front suspension section (pg 67). They have one 3/8 forged steel, tapped for fine thread. Is this similar to the original application on the 46 brake MC? If so I will look at the possibility of matchup with the universal MC rods (pg 46).
Thoughts,
Cavebull | | | | | Joined: Mar 2000 Posts: 784 'Bolter | | 'Bolter Joined: Mar 2000 Posts: 784 | Cavebull, I just used the clevis off my orig master cylinder. The dual master I got had a round loop on the end of the push rod. I just cut that off and threaded the rod, and used a long connector nut to tie everything together. this also gives you some more adjustment options.
George | | | | | Joined: Jul 2006 Posts: 451 Shop Shark | | Shop Shark Joined: Jul 2006 Posts: 451 | Hey George,
I am sorry. I failed to mention in my post that I have no rod nor clevis. I am starting from scratch looking for a similar replacement. I would prefer that to modifying the brake pedal if possible.
You have the original brake shoes on the front and back of your ride, correct? With this master cylinder I assume you made some, if not all, of your lines. Did you use stainless - single flare, or steel and double flare?

George George, I'd like to check out those pics too. I might upgrade my master cylinder for a winter project. Thanks, john. | | | | | Joined: Mar 2000 Posts: 784 'Bolter | | 'Bolter Joined: Mar 2000 Posts: 784 | Cavebull, Yes my brakes are all stock, Huck style. I used steel lines with double flare. Seemed to be the best route.
John, the pictures are on the way.

Send me the picks as well, I am working on my Dad's 46 1/2 ton, His original MC won't keep pressure. After you release the brakes you have to pump several times before you have brakes again. I have convinced him to upgrade to a dual MC and need to know how it has been done befoe. I was planning on fabricating my own bracket since I am not able to find the right one from list of vendors out there. The idea came from the article in the Tech Tips. | | | | | Joined: Feb 2005 Posts: 338 Shop Shark | | Shop Shark Joined: Feb 2005 Posts: 338 | Here is a link to my web page. It shows pictures of how I did it on my 1940. I am using the Buffalo Enterprises bell housing and a T5.

I just lopped off the back half of my original pedal bracket and welded a plate I made that I could bolt the master cylinder to. The original clevis and rod is used to link the pedal to the master cylinder. | | |
