What brake swap is this????

Hey everyone, I just got a 1975 cj5 w/ 304ci. It had a brake swap done to it and I have no idea what they are off of. This jeep has been molested up and down! And there is all kinds of stuff changed around and swapped out. I guess I can't complaint too much since it was free! Here are some numbers I pulled off of the parts. Rt rotor 121.63004 or 6741 02-00. Rt caliper ST8G 3. The diff tag says 5350863 3 73 41-11. I just need to replace a caliper and master. Thanks

I spent hours and hours on the interweb and found that its is the Chevy truck disc brake conversion! It has an ssbc adjustable prop valve by the rear axle. I have to get a new master cyl and was wondering if I could use a YJ master and booster? Also how many prop valve do I need I thought two but I'm not sure?

That is indeed the Chevy (or Jeep) Dana 44 brake swap. The calipers and stands are off of a Jeep or Chevy Dana 44, the rotors would be '77/early 78 CJ thick rotors. I did the same swap on my '75 when it had the Dana 30 front axle. I used the stock master cylinder with the residual pressure valve for the front brakes removed. The stock prop. valve worked fine as the weight bias didn't change as a result of the disc brakes in front.

Prop valve just adjusts braking bias between front and rear, so only one is needed.

That depends on what master cylinder you purchased.
