Choosing a disc conversion kit

[Smokinnjokin]

Its finally time to do the manual drum to disc conversion for my ‘67 satellite, and i am having a hard time choosing, there are a lot of options.

PST and Dr Diff are both highly recommended, at this point i guess it comes down to fitment and component quality.

I have 15” scott drake front wheels, was planning on doing the largest factory style kit that will fit with a manual master cyl. Thoughts? Dr. Diff has been ‘out of stock’ for a long time, but has more options than PST.

My biggest concern is hassle free installation.

Option 2 Purchase parts for 73-76 Dart from Rock auto calipers, rotors and get a set of Forged Spindles from same years as dart.

I like the wilwood disc brake kit. Easy to install. Don't forget to order the brake lines thats required for the kit.

How does the stopping power of this route compare with the conventional kits? The calipers seem undersized at a glance but I'm not certain.

Something to consider in your swap. Which conversion can you get replacement parts for in under a week when there is an issue? Thats one of the benefits of going oe based conversions.

No difference all dot approved I’ve used that setup and originally recommended by Richard ehrenberg from mopar magazine

I used the "disc o tech" setup in the late 80's on my Challenger. Made sure I used the 11.75" rotor setup for max leverage/swept volume/stopping power. Along with that on the front, I put 11x2.5" rear drums from a wagon on the rear. Worked very well.

I have used Dart, Volare,E body and Cordoba on many B bodies over the years and never a problem even on 10 second bracket cars.

What is correct donor car to get the master cylinder i need? 4-stud mount on '67 b-body, is there a version of raybestos MC36412 (1-1/32 bore) that comes with the 4-stud style mount?

 

[bolson6333]

For the race cars I liked to use the Mopar Performance with a I inch bore and used an adapter from the 4 bolt mounting to the 2 bolt cylinder. for a street car a 69 or so with disc should work fine. Your raybestos # crosses to MCA 88787 available at parts store like Carquest.

This is what I have on my hemi car perfect

Use a Mopar oe setup whatever you do. Did the conversion on my RR, stops on a dime.

 

[ckessel]

If you do decide to go with non oe, like Willwood/Baer/StopTech etc, do yourself a favor and have some service items in your parts stash. Pair of rotors, caliper seal packs, pads, pair of flex lines. Replace them when your inventory gets used. Nothings a pisser like when you need something and its not available.

Master Power on my car.

You shouldn't have to tie yourself down
with high $ after market kits. Jeep used
the same axles, and the selection is more
plentiful and a lot cheaper than Wilwood.
The brakes on my rear axle are pieced
together. Ford Explorer calipers, Chrysler
rotors. With a little homework you can find
the backing plates by matching up the bolt
patterns on the axle flanges.

Can't help much on the front as mine are Ford
with rack and pinion on custom A-arms, using
Ford PINTO spindles.

Wow that frame is a work of art! And no, i am not interested in aftermarket kits like wilwood, strictly OE.
