I recently updated my rear differential to disc brakes, no longer have to deal with drums. But now I’m not getting any braking power on the rear, and I’ve already changed my master break cylinder and have no leaks anywhere-it’s new. Any thoughts?

Can I use a disc/drum master for four wheel disc brakes?
Usually not. For 4 wheel disc brakes to function properly you will need a master that has a longer stroke.

And proper proportioning valve..

See explanation here..

Thanks for your insight, guys, it was very helpful. I will change my factory proportioning valve from a "combination" to a "disc/disc" to get an even brake power. If that doesn't do the trick, I will change my master brake cylinder with a hydraulic one. I'll keep you updated! Cheers!
