Ok I orderd a power brake unit for my 51 f1 its got a disc/drum master cylinder
is there any way i could use that master cylinder on a drum/drum set up?

 

The Disk/drum master will not work propley for a drum drum set up.. but you can get a drum/drum master from www.mpbrake.com for you truck to bolt up to the booster your getting.. Just save the disk/drum master for when you install disk brakes..

 

Good excuse to go ahead and convert to disc brakes. Believe me, you won't be sorry. It's the best single upgrade I did to my 51.

The only reason a disc/drum MC would NOT work for drum/drum is if it has built in proportioning valve and or residual pressure valve, many do not but use a separate valve. all you would need is the correct proportioning valve or an adjustable one. The biggest difference between a disc/drum and a drum/drum is the former has a larger chamber for the disc brakes as they require more volume. Check with your manufacturer tho for the definite answer.
