I have his 11.7” rear disks on my Duster. I had no issues bleeding them and they work great. My parking brake is hooked up and also works great. I use his 15/16” master cylinder, his 13” front disk set up and an aftermarket adjustable proportioning valve.
have you asked Cass?
@DoctorDiff ?
The e-brake moves the piston, no drum set up.
