Quote: could someone explain why my 70coronet brakes perfectly with NO prop valve at all? i put an 73up A body disc setup up front and retained 10 inch drums in back. i was going to get an adjustable one but since it drove fine been about 5 years now. are my drums maybe just pooched? i've been curious about it ever since. sorry to hijack. Same here on my 70 Dart and 72 sat. Converted to disc, never put a prop valve on either, just used the correct master cylinder and it works fine. No wierd brake wear or anything. Not saying that will be the case on all conversions, maybe I just got lucky. 70 Dart Swinger 72 D-100 440 shortbed 76 Pinto, 68k 21mpg!

It has the valve inside but its only for the brake light in the dash. I can only speak from an '73 model perspective, but in the '73 factory service manual, you are indeed correct---only for an A-body. All the other models show an actual proportion valve. Thus in replumbing my brakes in my '73 dartsport when i did a manual brakes, aluminum 2 bolt cylinder and line lock, i removed the distributon block and used theline lock to split the fronts. The rear was feed directly off the M/C. Car had discs fronts and drums rear (10"). I never had a problem with the few panic stops i encountered, but the rears would slightly lock first. And lets face it, in my application with 3.5" front wheels with 165r15 tires, the fronts werent going to do a whole lot. Just my personal experience in modifying and doing a little research in factory systems---your experience may vary. Outcast Dodge guy.
