Who has Dr. Diff 8 3/4 rear discs?

Did you have a problem bleeding them?

I have his stage 1 rear disc kit with the mustang calipers, his 15/16 MC and his 73+ A body front discs on my 70 Dart with a drum distribution valve.

When the car is jacked up in the rear, idling in gear, I cannot get the rear wheels to stop when I push on the brake pedal. The wheels will slow, but won't stop.

I have bled them all along with the master, but I am out of ideas. I don't have parking brake cables, but did actuate the lever about 2 dozen times before bleeding. I haven't tried holding the lever (applying the parking brake) while bleeding, yet. I am getting fluid to the rear and can NOT turn the wheels by hand, if either brake or park brake is applied.

When the car is in the ground, it will stop if the car is idling in drive, but haven't tried it at any kind if speed.

Any thoughts?

No problems whatsoever with the kit itself. It went on really well, no problems bleeding them. You are better off getting everything from Dr Diff, his E cables and everything else is top notch.

My only issue is the powder coating is flaking off way too easy. Obviously the calipers didn’t get pre baked to get all the oils off the bare castings.

I have heard that some people can’t get the stock distribution blocks to work after messing with them...

If I ever have problems bleeding a new caliper, I usually end up cracking the bleeder over night... If that doesn’t work, I Clean them out and sometimes put a new rebuild in them.
