I used the CPP boosted master from botp I think. It is corvette style. Had I known that I would have used the Mustang booster and truck master instead but I had just bought the truck and I am happy with it I guess.

Although GM they ate at least 3/4 to sized parts.

 

TSR used my spindles to do the original setup for the F3. They were very good to work with and gave me a nice discount on the set. I sold mine to another guy on the forum because I went with the Jag front end. He said they worked as well as I though they did. They stopped my F3 with a 5.0 EFI 5 speed very well. Hope that helps.

 

Wow, I really like the idea of using your setup vs the antiquated Chevy setup.

Some questions: Do you have a schematic of the caliper bracket you fabricated? Where did you source the calipers & rotors from? What is the bore diameter of the master cyl you used? Do you think using the under-the-floorboard master cyl & booster would be the way to go with this setup? Thanks!

I'm currently using stock drum brakes on my 1950 F3, but I plan on towing ~2000 lbs on a towbar (race vehicle) and would like to stop when needed.

 

No I kinda just winged it, had dimensions scribbled on bits of cardboard and such while making them. Holes are filed to finish fit. They were not hard to make. I did not have backing plates but if you did you could just copy the bolt pattern from there, or measure like I did. The spacer between the 2 pieces of 3/8" plate is only 1/4" but probably plenty strong. They are fully welded both sides all the way around. I used wooden wedges to jam the caliper in place. Then with the brake pad outter edge in from the rotor outer edge by 1/8" and marked the mounting holes there. I had measured and figured I needed the 1/4 plate to be 1-7/8" but being lazy I just used 2" and put a washer on.

The calipers were also switched left to right.

I bought all the parts from Orielly's, I would have used Advance Auto but they do not exist in WA where I just moved to. The master cylinder is the normal boosted under floor setup for disc-drum from CPP. Corvette style.
So yes I think under floor is the way to go. I think it is cooler/neater. I may one day make a hanging pedal system that still actuates the under floor system with in cab linkages.
If you look around people use the antiquated Ford system from the early 80's it does use the same rotors and same SIZE calpiers but they mount with those weird rubber blocks with stainless strips around them.

I like what I have, after I finally learned how to adjust the rear drum brakes. It can stop HARD. Have not done a full on brake test yet, but I will when I get back from Japan(work).

 

I think I should clear up the dual piston calipers used on Ford trucks over the years:

Well that is most of them...

 

Great info, thank you!! I think I can do this!

 

How are your welding skills? I am not certified and learned to gas weld and Arc weld from my Dad. TIG and MIG I bought and learned by myself with much internet reading and leveraging off the knowledge my Dad gave me.

 

Pretty much the same here...I'm not a certified welder. I took 2 semesters of TIG welding at my community college. I've been MIG welding for ~10 years now, making furniture pieces, auto restoration projects (structural & not) & the occasional art piece. I learned MIG from a rollcage and off-road truck builder, he's a very patient and knowledgable fellow. I have a Miller 211now, but started on a Miller 420 GoldSeal.

That is an awesome thing you have done here! I don't want to violate my "Baby" with GM parts either.

I have access to a full machine shop and all the welding equipment I need. If you don't have the patterns for what you did. Could you give me some idea as to how your process went down?

Should I get all the parts from the newer truck first and then do all the fabing or what?

Any help will be appreciated!

 

I did not really make any templates. I just fitted all the parts together.
I would say to start by making the 3/8" plate that fits in place if the old backing plate. I think I made that plate about 1/2" bigger all the way around. This has to clear the rotor so it is a good idea to have ask the parts when you start.
Next I bent up the piece of 2"x1/4" plate that is the webbing between the two 3/8"thick plates. This has to hug pretty close to the axle flange because the caliper comes really close and it almost just barely fit. I think I had to grind/bevel the able flange for my wells because it was that close. I would say you don't need to weld the inside there.
Next you make up the caliper holding bracket out of 3/8" plate. When you look at the caliper mounting bracket you can see my bracket ended up with the mounting points being angled outward there are some massing angles for the bracket to engage.
I used a wedge to jam the caliper on the rotor while it was all assembled on the axle to position the caliper. I set the caliper so the edge of the brake pad was about 1/8" in from the outside of the rotor as this seemed about right.
Now to bring the caliper perfectly centered on its range of motion I put a 1/8" washer between my bracket and the caliper.

Sorry I do not have dimensions. I am more of a fly by the seat of my pants fabricator.

 

Thanks Jules! That little bit of information set me on my way!

I have access to a complete machine shop so I am sure I can manage. I was just wanting to get a starting point idea.

Thanks again!
