1972 Blazer Rear Disc Brakes

If you want to part it together yourself you can use the rear calipers off a 77 Eldorado, they have a built in parking brake.

the Eldorado calipers are small and only use a lever to apply pressure. the Tahoe calipers are twin piston and use a drum in hat emergency brake... that would be my preference.

Do not back up with the parking brake on if you do the drum in hat axle (don't ask me how I know!).

What master cylinder and booster are you running with that set up?

So I have a unique setup. I have large twin piston calipers front and rear. I also upgraded to hydro-boost from the 2005 GMC 2500 that my rear axle came out of... I used a wildwood adjustable proportioning valve to be able to adjust as needed...

There is a lot of good information to read over here....
