Question about disc pads (inside and outside) -- aren't the pin-type pads slightly larger in square surface area vs the slider type pads? IF yes, then there is an advantage, IMO, to having the pin-type calipers (or whichever is larger, speaking for both the inside pad and the outside pad).

Dunno, I do know that the pin type has more options in regards to friction material choices though thru Hawk. But Firm Feel does have some for the slider types too.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

I have done this swap on both my 71 Road Runner and 72 Charger. All you need since you have discs already is the Dr Diff spacers, B-Body 11.75 pin adapters and rotors. As said above C-Body will not work. Your calipers, hoses and hardware are a direct swap. I used Wagner BD60475 rotors and Bendix CQ ceramic pads on both.

In 1973, the pin caliper's fluid port location changed.

Hose routing is funky when this caliper is mounted toward the front on muscle era Mopar A,B, and E bodies. When this caliper is mounted toward the rear, the brake hose banjo bolt hits the lower control arm before full lock!

'70-'72 pin calipers are fairly scarce and costly. These fit nicely when mounted toward the front, but hose routing suffers when installed toward the rear.

Due to clearance purposes, most pre '73 A-bodies equipped with sway bars and pre '70 B-bodies equipped with sway bars require rear mounted calipers.

Wow, thank you for that. I my calipers have been sitting for a decade. I hope they are still good. I can rebuild them I believe though.

Dr. Diff, if I wanted to upgrade to the 11.75 rotor on my 71 Challenger. It would appear I need your sleeve kit to make it work?

Yes. The spindle sleeve/seal kit allows you to bolt '73 and newer rotors and wheel bearings to pre '73 knuckles.

Question -- Can the 72-older (72-71-70) pin type calipers be used on the 11.75 rotors... and must they, then simply, require the B-body caliper brackets for the 11.75 rotors? Also, will those 11.75 pin-type caliper brackets properly attach to the 72-older e-body disc brake spindles?

I believe the answers to above ar YEs, but, i just want to be re-confirmed.... then I'd need the DrDiff sleeve kit instead of swapping the spindles.

Yes, on all counts.

DR Diff/Cass -- T/Anks for the confirmation... saves some $$ to spend on other items.. such as your rear disc 10.75 setup! I'll contact you soon!

Now, I just need to locate the B-body 11.75 pin-type brakets (front end of car is apart now... timely to find them!!!).

I just picked a set of brackets up off a 1978 Dodge Monaco (the basic Monaco was on the B-body platform)

Everything checks out to being the correct ones, so once I get them cleaned up and order up the Dr. Diff stuff. I'll do an article on the upgrade.

Before you have too much time invested in those caliper brackets, run a tap through the caliper pin threads and make sure they are good. In your pics they look a bit rusty. They can be nearly impossible to heli coil as there isn't a lot of meat there to hold a sufficient number of heli coil threads to do the job. Been there, done that...had them pulling out/unthreading on me when screwing in the pins even after trying to loc tite the heli coil in place...that's one advantage the sliders have over the pin type brackets...

You're absolutely right, mine seem to have cleaned up nice, thanks to a thread chaser my friend let me use.
