Using mustang rotors for 4.5" bc

-
Thank-you VERY much. I was looking for Bendix #141017 and couldn't find it but like you said the Raybestos 6004R comes up good. Thanks again.
 
Mike, thanks so much for your reply and details; that helps me a lot.

I'm very curious about the interchangeability of other parts onto my car, and you mentioned parts from a Jeep Grand Cherokee. Are you referring to a ZJ (first generation)? And they would bolt up to a small bolt pattern axle on my car? Or, I assume this is the way to turn the rear small bolt pattern into a big bolt pattern to match the upgraded front. This is very intriguing to me because where I live, in Poland, Jeeps are very plentiful and parts are very available, and this would solve the rear brake problem as well. Excellent! Now, do you perhaps have any suggestions as to any possible swaps using front axle parts from a Jeep onto my Barracuda? Does anything fit? My father in law even suggested going that route because he has a 2nd generation Grand Cherokee and reports the brakes are outstanding. I had a ZJ for many years and felt the brakes were excellent on that Jeep as well, and I'm aware the next generation offers even better brakes. So if there's any way I can use Jeep parts on my Barracuda, I'm definitely going to go that route, because we don't have junk yards over here to scavenge vintage parts out of and shipping from the US is very, very expensive on these heavier parts, so it makes much sense to use what we have available over here and if Jeep parts can be made to fit, I'm in!!

Thanks again.

Hetman,

I haven't used them myself, but have seen the SSBC disc brake conversion for use on (I believe) the 10" drum brake spindle. They look like a quality product. IIRC, they can be had in either SBP or BBP configuration. If I had the money, I would consider them myself.

On the other hand, I've managed to scavange more than one set of the '73+ B/F/M/J/R spindles. Depending on which caliper adapter you have, they use either the 10-7/8" (good) or 11-3/4" rotor (better). The down side is they are heavy. A plus is this spindle is 3lbs lighter per side than the '73-76 A-bdy spindle.

There is one more option which, IMO, will maximize the performance of stock parts. That is to use either of the above spindles, with the Cordoba 11-3/4" rotors, and the AR Engineering caliper adapter which will mount Wilwood 4 piston calipers to the stock rotor. In other words, the best of both worlds.

The only down side I see is that those Wilwood calipers, IIRC, are not for four season use. I believe they do not have piston boot seals. In other words, maybe not best for daily driver use. But hey, I live in FL... LOL

This is the system I'm planning for multiple projects, paired up with the rear disc brakes from Jeep Grand Cherokee.

Hope this gives you more options to consider. Does your head hurt yet? Ha ha

Is anyone doing the modified rotors yet besides the Ramman who wants stupid money and is difficult to deal with

Good question, it seems like hes out of business or something: TRM - The Ram Man - TheRamManInc

I wish someone else was selling 4.5 rotors, Im sure quite a few would sell, Im not sure I can find anywhere that would take the milling job here in Sweden..
 
After being involved in a BO29 restoration learning a lot about these car. Chrysler actually made large bolt rotors on the a body spindles that they used on the 68 Hemi super stock cars. I aways thought they use B Body brakes, not true. Its to bad that Chrysler just did not just start using them on all A bodies. They were also available over the parts counter. Very hard to find, as I am looking for a pair of these rotors.

Interesting. Now the thing to do here is find an unmolested pair and get them repopped...
 
Fantastic thread. Will do this to my car. My new Wheels will be 215/65*15 in front and 245/60*15 in the rear. Magnum 500 7*15 and 8*15. Did buy them Before i had figured out how to solve the problems.
Thanks a LOT Longgone.

Where will you go for machining, somewhere local? Do you have any suggestions?
 
What are you guys doing for the centre bore? I cant find any hubcentric spacers for this size of 61.9125 mm?

I dont think they use the center

I dont know its the same design as stock just a different size.

Just to clarify, apart from turning down the outer diameter, in the first picture the highlighted outmost surface has to be cut down to the same height as the original disc and in picture two the bearing has to be removed and its seat has to be lowered by .271?
Last pic is an original disc for refernce.

Good pictures. Not got mine yet. As i understand that is the correct way. And use the old bearingseat for the seal. Will put them side to side as soon as i get them. Are you going to do it yourself?

Good stuff, oh so you will use the bearingseat from the old discs`s as seals a for the new ones? I wont do it myselft but I will go to different machine shops and ask, someone should take the job.
 
I'm interested in doing this to my 69 Dart 340 Swinger. What is the part number for the rotor that everyone is using? If it's posted I've read past it. Thanks.
 
Got super lucky and managed to find a guy in my town that did the job. He also made centric spacers for my new rims in a derlin fibre like material.

He CNC`d the bearing race as he was not confident turning it would be accurate enough. For the whole job he only wanted 110 dollars! I tried to give him more so we ended up at 130.

Will see how assembly and testing goes.

Im quite amazed nobody in the industry has taken notice,and just produced a ready made version...
