I bought a complete set up for converting my drums to disc. These came off a 71 Chevelle. Where does the porportioning valve mount? I didnt get the brackets with it? Does any one have any pics?My drum brake block bolts from underneath. The disc one bolts from side? Do I need something and any part # ? Thanks Guys.

Mine mounted on a bracket that held it up off the frame just under the master cly. The one that came with my kit is supposed to mount directly to the frame rail. The only problem is the header passes it with about 1/4 of an inch clearence.
I'm going to build a bracket to put it in the stock location.

Who did you buy the setup from? Does the prop valve have two holes in it through which to put the bolts, or is the bracket pressed on to the bottom of the valve?

I think I understand what you are saying, and it sounds like you have the aftermarket valve that will not bolt to the frame unless you build your own bracket. This type of valve will bolt to a bracket that attaches to the holding bolts for the master cylinder itself, placing it immediately, and just a few inches, below the master cylinder.

If that's the case, it's your call on mounting. I didn't want to make a new rear line for mine, so I made a bracket to mount the prop valve on the frame and tweaked the other lines and made some new ones. It was big fun!

The valve is a original Chevrolet with 2 holes in the side. My 67 one is attached to the bottom.

Interesting. My valve is an original all-drum valve, and it mounts with a bracket to the frame with no holes in the valve. That verifies what I have been told - that there were two styles used, as I have seen disc valves with the bracket as well.

I was told that the two-hole style was supposed to be bolted directly to the frame. I have not seen a photo of how those mounted. For me that would be a moot point, as I have headers and there's no way the valve would fit down there anyway.

I just made a little L-shaped bracket for mine and ran a bolt through the lower hole to the bracket, and then drilled a hole in the top of the frame and ran a bolt through the bracket to the frame. I don't know what you're going for as far as originality, so maybe that won't work for you.

Are you doing a factory-looking resto? If not, you have some mounting options.

Where did you buy the conversion kit from?

I bought a complete set up from GM Sports Salvage in SJ. I can make a bracket if needed? I was told the stuff came off a 68-72 Chevelle El Camino. Thanks again

I dont think the 1967 came with front discs? So the valve is just a juntion block and not a porportioning vale. Does anyone have any pics of a Chevelle or El Camino with the valve bolted near the left frame rail?

You can mount the prop valve anywhere you like. In the grand scheme of things it really doesn't matter. You may be right, that the '67 did not come with front discs, but I don't know for sure. If that's the case, your new valve will never look "factory" anyway, so you can mount it where you choose. Just make sure it's located so that it's not too close to the exhaust, and that it will not interfere with any clutch linkage if you have a stick.

If you don't have headers, and are not planning to add them, plus not having a stick, then you've got lots of room to play with the location. I've got both, so mounting was a bit of a hassle.

Do you want to mount it directly to the frame, or are you thinking of making your own bracket? The bracket took me maybe fifteen minutes at most to make. I just used some mild steel, bent it into an "L," drilled a couple holes in it...presto!

I've got a '68-'72 style factory prop valve that does have the little bracket to mount it to the frame, but the bracket is not removable. It is staked to the valve permanently.

J-52 front disc brakes were available for the first time in 1967. If I recall only about 500 cars got this option. The junction block number was part #3921043. Metering valve # 3905525. Master cylinder was 5435800

Alway great info ...thanks Guys
