Proportioning valve

[castrol69coupe]

Guys, I need to finish my disc brake swap, and its killing me to not
be able to. I need a 78-79 ish Granada proportioning valve. The one
my swap came with wont work, because it is missing pieces.

Help.

Someone on here has to know where I can get one of these things at
a reasonable price.

HELP ME PLEASE.

Thanks.

If a prop valve like that is used, is the distribution block still needed? Does this valve contain a check valve if there is a loss of pressure in the front or rear brake lines?

Check at the junkyards. I'm also pretty sure many different Ford vehicles used the same prop valve. Also look at Mavericks, and other similare sized FOMOCO's.

I don't have that exact proportioning valve, but the design looks to be simmilar to mine. The line from the larger resovoir on my MC goes to a distribution block which splits it out into lines for the driver and passenger side front brakes. The line from the smaller resovoir goes to the proportioning valve, to a pressure gague, then to the line to the rear drums.

No idea about the check valve.

I would second Opentracker's recommendation. When I did the Granada swap, I used a Granada proportioning valve. Well, it's close, but at the limit my back tires lock first. Not good.

The adjustable valve will always work, no matter what future brake mods you decide to do, or if you put in a bigger engine, put the battery in the back... any weight distribution changes the brakes can be optimized once again. It's a pretty useful thing to have, IMO.

Thanks guys. I just need to get this car back on the road ASAP. Its killing me to have it sitting in the garage like it is. Weather is getting nicer, and this thing needs to be OUT. Thanks for the advice.

That's the one I have too. Mine came with the Baer kit, is marked "Baer" but it's a Wilwood valve.

I bypassed my distribution block when I did the rear line; now the rear brake line goes from the MC, through the prop valve (mounted on the firewall), and to the rear brakes.

You'll get a brake fault in the instrument panel, but that can be eliminated by unplugging the sensor on top of the dist block. I left the ports on the dist block open, with the lines for the front brakes in place, and I've had no leaks or problems.

send 69StreetGrande (I think that's his name) a PM; he did a very nice custom job on his brake setup. You could probably find pics of it on his website:
