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
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.
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.
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. https://www.oreillyauto.com/detail/...101571/4559072/1975/dodge/dart?q=101571&pos=0 Pretty sure it's not going to work, and if not, which one do I need to get.
All of the 73-76 Dodge Dart manual disk brake units I've seen are over an inch. I'll look again. Thanks
