Re: braking
Mixing parts by an aftermarket adjustable one...that way you dont need to rip it apart again.
Make sure you start with a master that take discs. |

You always want to use an adjustable proportioning valve in any custom non-stock disc/drum or disc/disc system. Some, if not all, of the first valves used by Ford were also adjustable! Last edited by V8 Bob; 07-15-2015 at 09:26 PM. |

Re: braking
Adjustable proportioning valves are available through the street rod shops and Jegs or Summit.

Re: braking
I don't disagree with any of the above. Some aftermarket conversions (at least for 55 birds) include different rear cylinders, supposedly eliminating the need for a prop valve. Didn't work well in my case. You're going to want to start with a disc/drum master, then you have to consider residual pressure valves, and adjustable pressure valves. Some factory combination valves include some or all of the above.
If you're doing this on your own, go look at the aftermarket company kits, http://ssbrakes.com and http://www.abspowerbrake.com Are two that I've used. You don't need to buy a kit, but look at what's included. You'll need a good double flare tool, and maybe some other tools to make up the lines right. All doable, but brakes are not a place to make a mistake. If the old brake lines haven't been replaced, think about that. If you didn't do the hoses, they're next. My bird went from drum/drum, to disc/drum, to disc/disc, over the years. When you make an upgrade, the weaker parts show up. Well worth the effort to do it right. |
