Anyone know of a source for N.O.S appearing brake proportioning valves? I know Master power brakes has one that works, but is not stock appearing. Need one for a T/A. Any help appreciated.

For disc or drum?

If it's drum brakes. I can help you out with a fully restored one.
Let me know.

Ive never seen a PP valve for drums.Just a splitter for the dual master.Disc has the valve.Rocky

Disc setup has en extra metering valve connected to the main valve.

If you do have disc brakes, this picture might
help you identify exactly what you are looking for. see attachment.

AFAIK only available used.

I think this is an E Body thing. Here is a picture showing the third piece mounted to the driver side frame rail, inline with the rear brake line. I've seen this on a couple of 70 Challengers.

Third piece is not used on cars built after 1/1/70, as the P-Valve was combined with the safety valve on disc brake cars after that date.

The five different types of 1970 valves.

Is there any difference if the car has disc front and rear drum?

Unfortunately Jules, mine is a disc fron/drum rear car, with the set-up pictured by Beeb-Beep. "Still looking."

"IF YOU'RE UNDER CONTROL, YOU AIN'T GOING FAST ENOUGH."

It is my understanding that the metering valve is used to restrict front line pressure in disc/drum cars to allow the rear drums to overcome the return springs before the front calipers start to clamp down. In this manner, the brakes are used evenly and wear evenly, otherwise the caliper pads might wear much faster.

Where can I get a metering valve?

I have a 66 Dart with a Ford 8" rear (Ford 10" drums) and I have 75 Dart front disc brakes. I am using the 75 Dart proportiong valve/loss indicator, but I have no metereing valve.

Do A bodies even need it, or is it only used in heavier cars?

I wonder if the A bodies even had metereing valves, because looking at those pics it seems like one of the two ports for the front calipers on the prop. valve is plugged, one line goes to the metering valve which tees them to the front calipers.

My 75 Dart proportioning valve did not have a plug in either one of the front caliper ports, so I just connected them directly to the front calipers as was recommended to me. The brakes work great BTW, at least compared to the old 4 wheel 9" drums!

I'm confused now as to whether I'd even need a metering valve.

My Cuda had the prop valve and seperate metering valve as shown in beepbeep's pic. A few years ago I did a complete brake job and couldn't get the front calipers to release. The metering valve was clogged. I was able to bleed the front brakes but the calipers would not release. I tried to clean it out by soaking in pb blaster for a few days but still couldn't free it up. I ended up bypassing it and have no problems with braking front or rear for over 2 years now.
