Of the 3 factory braking options, drum, disc & power disc, did they all use the same fluid portioning valve? Was the disc & power disc valve the same? Drum valve different?
The drum & disc brake porportioning valves are different. There is no difference in them, whether they are power assisted or not. Hope this helps
Yep. That's what I needed to know. I'm taking the power brake booster off my drag car and installing a non-power brake master cylinder and pedal assembly but will leave the disc brakes on front.
