Alright, getting ready to put the disc swap onto our 65 Valiant.

I have the following

from a 87 5th ave
Spindles
2.75" calipers (front mount)
11" rotors (just shy)

From a 73-76 A body
Uppwer control arms
Upper ball joint
Lower ball joint (bolt and nut style)

We plan to use banjo lines from a 69 Camaro, seems this is the thing to do. We're also replacing the lines front to back, splitting it into two circuits and putting a dual resivior MC on. Still need the adapter plate, but that's in the noise.

Assuming (yeah I know) this is all good, do I need a "special" MC pushrod?

so i'm assuming you're doing manual brakes? you need a manual brake push rod. make a wanted add or get one from Mancini or Dr Diff. make sure you get the rubber piece that holds the rod in the MC

Yes, manual brakes.


Thanks

Never heard that before, other than a power version .
 
A brake rod difference for drum to disc, but its been a long time since i fooled with converting.
Maybe i read the question wrong.lol

Ah, i think it has something to do with the adapter adding 3/8" but I'm not 100% sure, hence the question. Thanks for clarifying
 
If your car was a manual brake car originally, your manual brake pushrod will work with your manual disc master cylinder. I'm assuming you're using a 73-76 a-body manual master cylinder.

Actually went with one from a 5th ave. That work?
 
I used the a-body master because it has a 15/16" bore and provides a better pedal feel. The larger the bore, the harder the pedal feel.
 
Correction, not from a 5th. Bore on the unit I got (Dorman M39476) us 24mm, just a tad over 15/16.
 
We eventually plan on swapping in an 8.8 rear with discs as well.
 
Ok, an update. To avoid having to use an adapter, then needing a different pushrod, I went ahead and bought a MC for a 73-76 dart. The one with the 15/16 bore was/is for power brakes, and the other one listed for manual brakes had the larger bore (seems backwards to me but I looked at a few different suppliers to make sure). Now, though, I have a master cylinder that doesn't have the retaining groove inside the pushrod grommet.

Pretty sure it's not going to work, and if not, which one do I need to get.

Specifically which one did you use that is for manual brakes with a 15/16 bore?
 
73-76 Dodge Dart manual disk brakes. Try Dr Diff’s prices because his kit is 100% complete for $450

All of the 73-76 Dodge Dart manual disk brake units I've seen are over an inch. I'll look again. Thanks
