I got an aluminum MC from Dr Diff for my 72 Challenger with manual brakes front disc/rear drum. Replaced the stock looking MC. Pedal height is higher, but much improved braking.Merry Christmas, I was looking at the universal master cylinder and they have a 1 1/32 and a 1 1/8 bore does it make a difference which one to get, going in a 74 duster 360 street car? Thanks
If you get one from him, be sure to get an adjustable MC push rod too. I got one from Summit for less than Dr Diff sells one for. Worked fine.Thanks Ricks70Duster340 that's what I was looking for
You certainly can, but if you use the 2 bolt adapter plate that comes with it the original pushrod will be too short to give full pedal travel.It says you can use your original push rod?

Ya that makes sense that it would be to short
Interesting. I was not able to get full braking with the stock rod. It was only after using the adj rod that things worked.100% not true.
DoctorDiff's master cylinders work just fine with the factory brake push rod, you do not need an adjustable length push rod. The factory brake push rod, with the DoctorDiff master cylinder and adaptor, results in exactly the same brake pedal height as with a factory master cylinder.
I have been running DoctorDiff's 15/16" master cylinder with a factory manual brake push rod on my Duster for over a decade now, I run one on my Challenger as well. Both cars were swapped from factory master cylinders directly to the DoctorDiff aluminum master cylinder with adaptor and both use a factory brake push rod, no change in pedal height.

So I want the 15/16 not the 1 1/32 ?
Have manual brakes. When I got the car the front disc brakes were not original so not sure what was correct or not with the MC. In my case to make the new alum MC work properly I had to use the adj pushrod.Did you have manual or power brakes? There are different brake push rods for manual and power, you can’t mix a power brake push rod with a manual brake a set up.
