69 charger disk brake questions

Got Dads 69 charger back, well he put some conversion kit on the front from a newer cordoba, or something cause the calipers are not where near correct, and the brake hoses make a nasty 180 degree bend and hit the front shocks.

does anyone know from a casting number if I have the correct spindles to put the correct 69 front brakes on it?

is 69-70 C body stuff the same?

Post some pictures of the spindles, calipers, that you have.
Factory 66-69 B body disc brakes are BENDIX 4 piston calipers.
NO, C body brakes are NOT the same.
69, 70, C body would be Kelsey Hayes single piston disc brakes.
Totally different manufactures and designs.

Post a picture if you can. The late model brakes can be made to work but you'll need the correct caliper and hose combination. Doctor Diff can set you up with what you need if you don't want to do the leg work yourself.

Typically the best setup is to have the calipers rear hung then use late model FMJ calipers which were designed to be rear hung and then use a custom hose that has the correct ends and the correct length.

Andy F, are you making the ported water neck extension? Sorry to pirate the post, but I can’t get a response from you or your dealers.

Phil

69 Imp also used the 4 piston calipers.Ihave a set from the 69 I scraped.Rocky

Yes, that's true.
The Imperial carried over the 4 piston caliper brakes to the 1969 model year.
But The Imperial brakes are BUDD disc brakes.
Still totally different from the B body BENDIX brakes.

Don't think the Imperial line of cars, was ever designated as a "C" body, anyway.

Calipers should be in the front of the spindle..if mounted in the rear, the hose will be bent..

Calipers need to be rear hung on the OP car to clear the anti-sway bar. The FMJ calipers are designed to be rear hung so they'll work just fine.

I covered all of this in my B body book.

We would like to put the correct 4 piston stuff on the car, if anyone has the kit, spindles, and brackets, i would be interested. ill buy new calipers.

I cant load my pictures off my phone cause they are in the wrong format. I will retake them and load them.

The correct Bendix stuff is super hard to find. Ram Man is making a one piece rotor to replace the original two piece and Hoffman has reproduced a bracket or two. I'm not aware of any source for the calipers though. Wheel bearings wouldn't be an issue but I'm not sure about the inner seal. I think Inline Tube makes the cross over brake line and I'm sure you can buy the correct hoses. Not sure about the pads.

If you're serious about using the original Bendex setup then you should start a thread in the Restoration area. Oh, and check the balance in your savings account too!

Getting parts for the Bendix disc brake systems isn't that difficult anymore in this day and age.
Just gotta know where to look to purchase the parts.
Piston rebuild kits, individual pistons, are available from ebay, and Amazon vendors.
Rock auto too.
As far as complete calipers, again check Rock Auto, and any parts store that carries the Centric line of auto parts.
You can rebuild your own existing calipers, or send them out to the professional vendors that advertise, doing that type of work.
As far as rotors, there a couple of vendors that sell a reproduction one piece rotor, and another sells a original two piece rotor that you reuse your existing hub that you remove from the old and reinstall onto the new.
Repop caliper hard lines are available from the companies that sell fuel, and brake lines.
Repop caliper hose brackets are available.
Calipers bolt directly to the spindle, so no bracketry is neeeded for that.
If the OP needs original 66-69 Bendix disc brake spindles they come up for sale from time to time on the internet web sites, or placing your own wanted ad.
Buy yes, some of this stuff is expensive, $$$$$$$$$ dollar wise, depending on which way that you want to go, but all is available.

NAPA on line sells a rebuilt caliper. I think after talking with a few companies today im going to do a A body swap kit...

Well, what type of brakes are on the car right now?
You ever want to know, figure that out, anymore?

So who makes a repopped single piece rotor for 66-69 Bendix? I have only see the rotor that requires and original hub to mate too it.

There is this wonderful thing on the internet, called GOOGLE.
Do your own search, and homework.
Ever think of ebay, too?

Its harvest time so I have been in the field. I snapped a couple JPEG potos last night quick when I finished up the corn.

Hope these are good enough.

sorry guys Im not the greatest with pics hope these help

Looks like you already have the late model brakes on there so no point in doing an A body swap. You just need to change the calipers so the hose comes out the bottom instead of the top. Whoever did that swap used the wrong calipers for that application. You need the late model FMJ calipers and then new hoses. I think I already told you this in a previous post.

this is the only post I have on this issue.

I wish Dad was sitting here next to me so I could ask him WTH he was thinking sticking the hoses on like this

These calipers use the slider bolts,

Well, those are what's known as "pin type" calipers so they can be 70-74 Barracuda, or Challenger (E body) calipers, or 70-72 B body calipers.
As for as the Spindles go there are 2 types that were used.
70-72 spindles have a smaller diameter, inner wheel bearing to be used accordingly with that rotor.
73-74 spindles used a larger diameter inner wheel bearing.
You would need to take off a caliper, and rotor and measure the diameter to tell what's currently on the vehicle.

Also, looking at the disc brake dust shield in your picture, it looks to be a 70-72 shield, so I'm betting on either of those years, that's whats currently on your car.

Ok,

Kinda makes sense. the V code triple black 70 challenger the drive train came out of, 440 sixpac, hemi 833, and 3:54 dana all came from a 70 challenger. Long story there....

it was a gas crunch and Dad swapped a 318 and 318 drive train into a guys 70 V code and the guy paid dad for labor and they swapped drive train..

Hey the guy came to dad LOL

I would have just swapped him the green 70 challenger the 318 and parts came from lol

Soooooo, now that I know what I have, I can just order a booster and master cylinder, and get A body calipers and mounts Id expect.

I might just turn these rotors here at work.

Ya, you can install A body 73-76 "Slider Type" calipers onto those spindles Ok if you want too.
Your right, you would need Slider type caliper mounts, and accordingly slider type calipers.
If your going to keep calipers mounted toward the rear, your gonna need hoses to work with that swap.
People use hoses from the Aspen, and Volare cars, without any problems.
FYI, i have slider type mounts. Wanna buy a pair?

I may have a set off my Demon as I put willwood on the front of it. If I cant find the mounts Ill PM you. I sent ya a PM already so we will keep in touch


thanks!

anyone out there have any positive or negative opinions on these

Look here.
I knew i had it filed somewhere in one of the computers that i use, but i didn't know which one, until i found it.

This is what I recommend:

New, powder-coated rear mount slider calipers, pads, hardware, flex hoses and caliper brackets $200

Thanks Doc...

Ill be in touch

I have the original stuff off of my stock disk 67 R/T. I switched it to the Master Power Brakes kit for the disc to disc conversion.. Therefore, I used the same spindles but took off the calipers and rotors. I am sure they need work and would be $$$ to ship the heavy beasts. They will sit in my garage until I sell my car and I will offer them with the car.
It was just so much more expensive at the time to rebuild them and deal with the pads and for safety preferred the new A body calipers.. Actually back then in 2009 we couldnt find anyone to rebuild them or a source for rebuilt calipers...
THe MPB kit has been great. Now 10 years later I am getting my front left caliper hanging up every now and again and it smells toxic. Need to figure that out.

Looking at that rotor I bet your inner disc is well below minimum which was only .94 with a disc that started at 1.

New one piece disc for the small bearing spindle are just $55 Rock Auto.

New pin type caliper for the 70-72 B/E also pretty cheap at local auto store or RA.

I had to go through all this with a 70RR.

You just need to verify which spindle you have, but if the 10.98" rotor it should be the small bearing.

Your most likely right.
Never personally had to research it any further, when that page first showed up, as I'm not in the market to purchase one.
Then it's advertised incorrectly.

How about this one, sold by Year One?
Appears to be correct for fitment on the 1966-69 B body line of cars for the BENDIX disc brake system.
I knew someone has (had) these rotors, but i was confused where i saw the ads, and who is selling what, and how i bookmarked them in my computer(s)
That's my error.

"Reproduction rotor and hub. Improved one piece design. No pulsation like original two piece rotors that expanded at different rates. Wheel studs with right hand threads already installed. Works with original Bendix or Kelsey Hayes caliper's."

I had to do research for my 69 disc b body. I separated quite a few 2 piece Bendix and KH rotors to take measurements.

I still think that one is a problem too, though I have not personally seen one. Look at the note above. Says it works with both Bendix and KH calipers. Clearly not meant to. Bendix was the 11.19 and KH 10.98. Plus height/hub differences and spindle mount surface offset. I think this may be a bastardized rotor in the middle. From what I read, folks had to turn down the inner surface to get it to work with a true 67-69 Bendix set up.

It really would be more helpful if Year one and others provided the full spec like RA does with their 70-72 Rotor.

The dura brake rotor only is made to the Bendix spec, you just have to mount the hub correctly.

I suspect that Year One ad has gotta be a miss statement in the description stating Kelsey Hayes calipers.

There now is a one piece rotor that's available for the 65-72 Kelsey Hayes, 4 piston disc brake system, used on the A body line of cars.

Mancini is selling them.
Check out the ad, in the link.

There are various threads floating around the internet on the Year One rotor for Bendix brakes. Everyone seems to agree that it is a bad Chinese reproduction part. Ram Man has a video where he shows his Bendix rotor and explains why his rotor works and the Year One doesn't.

I did a quick search yesterday and did not see any listed on ebay, other then the dura brake rotor only. I did not find ram man rotor either. His website has changed and not all sections have stuff in it. I will look a little harder.

I just imagine disc brakes for early b bodies being a new thing to mopar did not have sufficient productions numbers to justify the variety of reproduced rotors that A bodies and Later B&E did. Especially as disc became more popular.

I actually have a set of single piece KH rotors made for the 70-72 B as over the counter replacements. But Bendix rotor and calipers seem much harder to come by at swap meets and such. I did score a useable pair for my 69 as backups, and purchased the dura brake set of rotor.

For the original poster it would be pretty easy and inexpensive to get all the correct 70-72 stuff on the car since he has the 70-72 spindle most likely.

You can tell the year of the disc brakes you have on your car by the numbers cast on the calipers.
1970 are KH80012
1971 are KH86166
If they are the 1970 calipers and you want to sell them let me know.

Those pictures shows the spindles are on the wrong sides,swap left to right, calipers will follow and sit in the front and the hoses will line up..

He can't do that, the calipers will hit the anti-sway bar. The calipers are on the rear for a reason. He just needs the correct calipers and hoses.

Yup!

Andy, I also have the small bearing spindles, but Dr Diff has the fix for that.

Ill order the stuff and get the hard lines taken care of, just waiting on more parts....


waiting and waiting...
