Re: [BaadAssGremlins] Re: I need a Proportioning valve!!!!!! Got one????



There is no proportioning valve in drum brakes on a 74 or any all drum
brake car. Are you talking about the brass block below the heater motor
that the 2 brake lines go into from the master cyl and then to the
front and rear wheels? That's only a distribution block with an
electrical switch in it to activate the brake warning light on the dash
should you loose pressure in either the front or rear brakes. I've never
heard of one of these going bad. If it is not leaking it is not bad. The
wire on my original 74 hasn't been on for 25 years. If you loose
pressure in either the front or rear brakes you will know it if the
light is off or on. Maybe someone has one off a parts car that has front
drum brake's.

I think there was a miscommunication. I do not have disc brakes.
I had planned on doing disc's but I couldnt wait to find a junker car for the swap.

I am rebuilding my current drum set up on my 1974 just to get it on the road.
I need the drum style porportioning valve. My orginal drum style porportioning valve was not repairable.

What year is your car? 74 was the last year for any US car to have front
drum brakes with disc's as an option. After 74 all cars had disc's on
the front. The thing that is needed to know is what year car did the
disc brakes come off of to properly ID them? Also did you get the
spindles with the disc brake setup. I understand that there is a slight
difference in spindles from drum brakes to disc's, but both bolt on the
same steering knuckle. I just unbolted the 4 bolts and took the whole
setup spindles and all from the 79 Concord donor car and just unbolted
the drum spindles and all and installed the disc's. Of course you need
the disc brake hoses which I used new ones along with rebuilt calipers
and had the rotors cut.. After 30 years of driving this car finally I
can beat on it with no brake fade.

My car has drums on all four corners.
Does that help?

I am not really up on identifying the difference in brakes but by years.
Maybe someone can be more specific in identifying the kind you have by
sight. I believe the 71-75 were the Kelsey Hays and 76- to at least 79
were the Bendix. The 70 and older were I believe 4 piston calipers or is
it 2 ? the later Bendix & Kelsey Hays are single piston calipers. If I
had the wheels off of both Hornets I could tell you. The new 74 has the
stock factory Kelsey Hays and my original 74 has 79 Concord Bendix
brakes. The 79 Concord 4 door sedan I parted out was a non power brake
car with no proportioning valve as was my friends other 78 Concord 2
door sedan which was power but without a proportioning valve. I plumbed
in a Wilwood adjustable proportioning valve before the disc brakes were
added and set it in he middle for the drum brakes and didn't have toadjust the valve at all after the disc's were installed as the car
stopped just fine. Oh it also has the stock drum brake power booster and
master. I have investigated this drum brake swap for a few years and
some people say you need the proportioning valve and some say you do
not. From personal experience I have to side with the don't need it
contingency. Both cars stop fine with the car with the conversion
needing a little more pedal pressure to stop as it has the single
diaphragm power booster where as the factory disc brake setup has a
double diaphragm booster. The additional pedal pressure is not
significantly noticed unless you drive the factory stock braked car and
then you can tell the difference.
