69 front disc brake q's, advice needed

[C500]

Folks,

I'm deciding what to do with the front brakes on my 69 C500. They are originally drums. First thing for sure though, I'm definitely converting to discs.

I have an old set of factory Bendix calipers here from a 68 charger. I'm considering getting a rebuilt set from Calipers on line, sending my old cores back:

Questions...

Other than rotors and Master Cylinder, what else is required to make the system work from the old drum setup to the factory discs?
Will calipers mount to the front, given I have a sway bar? Not keen to mount the calipers to the rear.
Is the brass junction box the same between disc/drum set ups?
Where can I get a new set of rotors from?
Any major problems with the factory setup, using the re-manufactured Bendix calipers?


Other option is to get a new set from SSBC. I want to run 14 inch wheels occcasionally. I like the idea of having the factory setup, especially with the Stainless sleeves.

Thanks.

Simple....just snag a set up of any 1973-76 A body car..Be sure to get the Prop valve as well off the frame...No BS, just good 'ol factory engineering...

And the best part? most times, they are cheap if in not too bad of condition...

Power booster and master cylinder should be off a disc brake car, as well as all the prop/distribution/metering valves.

Here is a good pic of what the booster and all the valves look like , and I have more if you need them should you decide to go with the original Bendix stuff

Valves and lines in the engine compartment

You are also going to have to change the spindles and dust shields since I believe the spindles are different.  The backing plates are certainly different compared to a drum brake system. 

*If you need a set of spindles and backing plates, let me know, I have an extra pair that I am trying to sell.*

Thanks for all the replies guys

GTX, the second brass box under the firewall, is that a residual valve, and only for a disc brake car? Do you sell the Bendix stuff?

Resq, can you post a photo or 2 of the spindles and backing plates you have, and how much you're asking please.

Thanks,

Kiwi

Actually I believe it's called a holdoff valve,
yes it's disc brakes only and
No I do not sell bendix brake parts

I do have a rebuilt original disc brake master cylinder, but I'm not to anxious to let go of it just yet( gotta deal in the works and I may need it )

Rick ebooger has some good master cylinders in the for sale section here under someone elses thread, so will probably use those.

What I will need:

Calipers
Master Cylinder
Booster
Distribution/proportioning/metering vavle
Spindles
Dust shields (optional)
Backing plates
Rotors
Residual/holdoff valve
Seals and bearings

Is hydroboost better?

Rick ebooger has some good master cylinders in the for sale section here under someone elses thread, so will probably use those.

What I will need:

Calipers -out there available to be rebuilt
Master Cylinder - I have a spare available for a rebuilt but missing the cap and bail wire
Booster - very hard to find but they are out there
Distribution/proportioning/metering vavle - should be available repro through fine lines or in line tube
Spindles will get pics for you as soon as I dig them out
Dust shields (optional) - optional but also available new repro but I have good used ones
Backing plates - disc brake cars use dust shields
Rotors - -available repro but from what I have seen and heard, have to be machined a bit on the hub area
Residual/holdoff valve- available new through repro such as inline tube or fine lines
Seals and bearings - available new at local autparts stores

I'm not having any vacuum problems, so can't see why I would need one. I also want to keep things looking pretty original under there.

Thanks   The new boosters available from MP and SSBC would do the trick.

[resq302]

There are new brake boosters out there but they look nothing like the orignals.  Just an FYI.

Cool, do you know who does good ones?

[resq302]

If you are wanting to keep it looking pretty original.  I know a guy called the Ram man had been talking about possibly reproducing the power disc brake booster for the Bendix units and he had some rebuilt ones at Carlisle.  Might want to look him up and try him.

Thanks, just found his stuff on ebay http://cgi.ebay.com/ebaymotors/POWER-BRAKE-KIT-BENDIX-66-70-B-BODY-COMPLETE-/390252626376?pt=Vintage_Car_Truck_Parts_Accessories&hash=item5adcde81c8

I would like to keep it factory, but cost is going to be a factor 

[resq302]

Well, my charger came equipped with factory disc brakes.  However, someone over the years changed them out to the later style single large piston.  I had the correct booster but I needed all of the other stuff.  Getting the stuff was hard as hell to do but I eventually pieced it all together one small piece at a time and when I could afford it got spares of it all.  Now that I have at least one of everything for the "just in case" should happen the day or so before a show.

PS- you might want to contact Wayne directly as I think his prices were a lot cheaper out in Carlisle.  Prices might be higher on Ebay due to the fees and such!

$750 for a PDB booster and cylinder?That seems high to me but hell everything else does now a days.

[gasoline_24]

I have a booster and master cylinder that I installed on my car that was rebuilt.  I believe I bought it from lilwendel on here.  It would not work on my car because of vacuum issues.  I paid $350 for it and would sell it for that plus shipping if you are interested.  I could send some pics if you need more.  Here is one of it in my car.  It could use another paint since some of the screws got knicked up during the uninstall.  This isn't a great pic, but it is all I have on here right now.  I can take some pics of it tomorrow if you are interested.

[gasoline_24]

Here are some more pics

[gasoline_24]

Here are a couple more.

[C500]

Thanks for posting the pics, I'll send a PM tomorrow.

Cheers

[resq302]

Finally, after digging through all of the mess of parts in my basement I found em!  If you want them, $150 plus shipping.  I will even clean them up and paint them back to the original colors for you so they are nice and pretty when they go on your car.

[C500]

Thanks for digging those out Brian and posting. I'm still sourcing everything, and will let you guys know in the next couple of days. 

[C500]

PM's sent guys   

Alright, one more question...... if anyone has one and knows how effective a rebuilt Bendix setup is, please post your comments.
