I have a set of scarebird disk brake conversion brackets for my '70 Challenger. I am wondering who has done this swap, what calipers and brake hoses they are using and if they are running a sway bar and gas shocks.

I bought these brackets, but I am having second thoughts and I'm thinking MP '73-'76 A body reproductions may be the way to go...

I used one on my 64 the brackets fit fine. For the brake hoses I bought fittings from AFCO and braided steel lines. once I replaced the bump stop for the upper control arms it was fine

I've got this same setup on my '67 b-body, and wasn't impressed.

I had to machine the plates to fit around the lower ball joint, had to have some spacers made for the oil seals to fit into the fury rotors once their bearing spacer was in place, and I am now using the recommended 70 b-body MC that doesn't seem to have enough capacity to work the truck calipers... My car hasn't been driven in almost 2 years now, but I'm hoping to get it back in my garage soon, and get this worked out...

I REALLY wish I had just used the 5th Ave discs I had planned on using...

racerAL, what master cylinder are you using?

This really concerns me, but I would need some '73-'76 Dart spindles(can't find any around here) to run regular mopar calipers...

I really don't want to open the whole F/J/M body spindle debate here, cause I'd rather not use those.

I was planning on running Crown braided brake lines if I couldn't find a decent set up...


What chevy pick up calipers? just 2 wheel drive 1/2 tons?

I was thinking a chevelle or Transam caliper myself...

I'm pretty sure the kits use different parts now, but mine used 90's 2wd GM truck calipers...

....I
am using a mid 80's reliant/k-car master cylinder.it resembles the MP piece but half the $.as a matter of fact i'am using the MP adapter.it fits perfect.i also use a in-line adjustable porpotioning (sp) valve,i can adjust the front and rear brake ballast.i'am not sure about how well this would work on the street ...but i have had NO problems stopping my 3400# car from the mid-11's at 120 or so..Also, i looked at my instr. sheet that came with the kit,and closer9 was correct.they had changed the kits.my kit came with the spacers and had been changed for ball joint fit,and also used mid 90's chevy truck calipers(2wd).

I'll look into that MC and the MP adapter. That may make all the difference...

Why not?

BTW, I have a SSBC in-line prop-valve in the rear line.

the "k" master doesn't have a provision for the rubber retaining ring for a manual pushrod ? or maybe not enough stroke ? this is interesting, as speedway motors sells a "chrysler style" master with an 11/16" bore for "disc conversion kits". i think this may be a "k" master.

Looks like a typo. I bet the master from Speedway Motors is a common 1 1/16" bore unit.

you mite be right doc. i never thought about a typo.....11/16 IS kinda small. i looked up the k masters in my wagner book and they list 7/8,21mm [.8268], or 24mm [.9449], depending on year and model.
