I am thinking of keeping the brakes manual and would like to use the stock pedals (clutch and brake pedal). What do I need to use for a master cylinder? It is my understanding that I need a dual chamber mc. If so, is there a dual chamber mc that will bolt in the original mounts, or will I need an adaptor bracket of some sort? Will I need a prop valve or any other device inline so the brakes work properly? Any pictures or part numbers from setups like this would be appreciated. Thank you. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Lemmm117, I would not recommend manual disc brakes, your pedal effort would be excessive. There are kits available to mount the master cylinder/booster under the floor and use your stock pedals. You will need to order a master cylinder for a disc/disc application (no residual pressure valves), and yes a proportioning valve is required. If you search for CPP and other suppliers of brake conversion kits you'll find a lot to choose from, hope that helps. | | | | | Joined: Feb 2000 Posts: 988 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 988 | Lemmm117 I have 49 3100 and I am going to be adding Disc Brakes to my truck too. I too am going to go with Manual brakes on my truck as well. I am not to the point of actually putting parts on my truck ( I have a son that would like to go to college first, kids!). Any ways I was figuring that I would use the master cylinder from an early 70's half ton truck with the Disc / Drum setup. I do know that will need a bracket to use the original pedals. I believe that most of the suppliers offer this bracket. I also believe that you will need a proportioning valve and possibly something else, but my mind isn't working right now.
Good luck

The problem with power was having to change or modify the crossmember. I also didnt want to move the MC to the firewall. It will be years before I am ready to test it, but others have manual front discs and are happy with the setup. | | | | | Joined: May 2006 Posts: 8,351 'Bolter | | 'Bolter Joined: May 2006 Posts: 8,351 | Bear in mind, disk brakes are not self energizing like the original Bendix Duo-Servo brakes found on the '53. Brake pedal effort will be higher than with the drums.

I found 2011 CHEV 1 ton express van rotors and calipers with all mounting hardware. I then purchased this unit per the recommendation of Hollister and other members. I also got the remote filler/reservoir and tool for the proportioning valve. It mounts in the stock location and uses the stock pedals. It only cost a few more dollars to do it the right way first!
