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?

 

Yes, manual brakes.


Thanks

 

Never heard of what exactly?

 

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

 

Actually went with one from a 5th ave. That work?

 

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?

 

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