Disc brake decision for a 1957 Ford

I building a '57 Ranchero. Power disc brakes have always been in the plan. The decision I have is to convert over to Granada spindles or use a kit that converts the original spindles to disk brakes. Both will provide 11" rotors. The Granada spindles need to be reamed to fit the '57 lower ball joint. In other words, the '57 lower ball joint connection is larger than the Granada's raising my concern regarding strength. When you look at the two spindles, the original '57 spindle ball joint material is greater.

My question has to do with the spindles with regards to safety. Is there a concern about the larger ball joint connection? The Granada spindle is the preferred Mustang conversion approach but the Mustang is a lighter car.

Does the Granada spindle have the benefit of 15 years newer metallurgy and made to address the heat of disc brakes? But then again the original '57 spindles will certainly insure original geometry but the Granada's are very close.

As additional information, I'm planning on installing a power Rack & Pinion steering setup. Don't know if that is important to this issue or not. It will have a small block Ford motor and C4 for a few pounds taken off the front. This car will be my daily driver on So. Calif. freeways and 5-7k miles a year.

You comments are welcomed. Thx in advance, r

OK...Just wanted to make sure you weren't considering a MUST II conversion. There is also now available a modified SAGINAW box conversion that will rid you of the linkage P/S.

As for disc brake conversion, the 70's intermediate spindle conversion seems to be a little heavier than the GRANADA.

Which system(s) interest you and I will post the info.

Disc options

The first and what I did before was the spindles off of a '74 Mercury Montego. Early 70 Torinos and Montegos go right on and are stout. I could do this again but getting to old for this level of pick-n-pull.

Next, is the Master Power Brakes. They utilize the original '57 spindles which has a nice ring and look like a quality product and all new USA made rotors, Calipers, etc. They like new USA stuff.

Third is DC Enterprises which use the Granada spindles. Another clean setup but my Ranchero might be heavier than the Granada. Components are re-manufactured with the spindles giving up some lower ball joint material as they must be reamed.

Replacing the 292 Y-block and cast iron automatic with a 302 or 351 and C4 should remove about 250-300 lbs off the front end. I think the Ranchero will weigh in at 2800-3000 lbs when done.

I'm interested in the pros and cons of the latter two options. Remember this is a long time driver for me. Safety followed by reliability followed by driving enjoyment are my priorities.

thx, r

I think you will find that the MPB KIT (among others) uses GM componenets...

The GRANADA spindle will hold the FORD and has been popular for the 57/64 upgrade. The intermediate is best in my opinion and a large yard should not charge too much to remove the components.

Let us know what you decide...

Great input!

Great input and threads.

You know, deep down inside a voice kept saying "...lets do the Torino Montego setup again..." Since a friend and I are going to get an engine and tranny for the '57 I guess I will take my pickle fork. Those kits are tempting though with all the pieces/parts.

thx for the information, r
