Maybe a silly question, but can you run the early 68-69 Kelsey Hayes without a power booster? If not can you just change the master cylinder to exit on the fender side? Thanks!! Yes they are the four piston calipers.

my 69 car came factory with NON power disc brakes! [on the fender tag also] so yes! they are very nice feeling with no power also! cant help on the MCYL sorry dan

Do you mean the four piston calipers? If so, I've got them on my Dart with no booster. I used a late model m.c., and they seem to work alright....

Yes you can as I removed the booster on my gtx many years ago and it stops just fine with no power assist.

Make sure you remove the power booster linkage on the brake pedal if you have it. The manual brake cars don't come with it installed. After removal the pedal ratio will be right around 6 -1 which is good for manual disc brakes.

Hello:
My 67 Dart GTS came from the factory with Kelsey Hayes 4 piston Discs with no booster, just as I ordered it.

They work great without the booster. My old 66 Barracuda came that way. Also, they were used from 65-72 on a-bodies, not just 68-69.

Yep. running them on my 69 RR with no booster. Seem to work fine.
