1969 impala disc brake proportioning valve
Permalink  

This is what I am looking for, but new.

1969 1970 69 70 Chevy Caprice Impala Front Disc Brake Proportioning Valve | eBay

 1969 1970 69 70 Chevy Caprice Impala Front Disc Brake ...

However, everyone wants to sell me one that uses at bracket off the booster.

1969 CHEVROLET IMPALA Summit Racing SUM-760185 Summit Racing Brake Proportioning Valves | Summit Racing

Summit Racing Brake Proportioning Valves SUM-760185

There is a 1969, Camero/Firebird block that looks the same.

Any ideas ?

Would a rebuilt one work?

If so, you could message John, 68sd396rag on here. He used to sell rebuilt units. He's getting out of the brake business but I know he still has some pieces left.

What you need Randy is a 69-70 Full size brake distribution block, a 69 bracket for it, and a 1968 69 brake metering valve.

Incorrect bracket. But I have a 69 bracket. You have to cut the bracket on the new, and weld onto the correct one. The bracket is staked not bolted onto the valve unfortunately. 

But you really could just go with used if someone might have one. I'm surprised you dont have one in your parts stash.

Correct bracket,

I have everything but the block.

I was thinking of cleaning up the original block but everything in this system is new or rebuilt.

I will message our member.

And if not, I will order the one above.

Thanks guys

I was thinking, by design, there appears to be plenty of meat in the bottom of the block. So If you do buy a new brass block, it would be no problem to cut the staking tab off, then drill and tap it for a short 1/4-20 bolt. No welding req.

This all looks ugly, but it'll blast up nice. You could just buy a hold off with a new plated bracket if you needed. The block bracket... you can't buy.

The steel block is dated 9 251 M if you want that too.

Sorry Mark,

The pic I sent was not mine, if was off the internet.

I have the same one you show.

The pressed one must be American.

The Camaro one uses a nut.

Great, so you're good to go.

Just buy a brass block and attach the correct bracket to it.

FYI - the 1969 & 1970 distribution blocks are different, and the line going to the rear brakes is a different thread between the 2 years.
I have a NOS 1970 distribution block if you're interested, but you'd need to order the lines for a 1970.

Clint, did the rear line become 3/16" in the 70?

I think the rear line is the same size as 1969, but the flare nut fitting is a different thread.

Hello John, 

Just curious. how would you get at the piston on these 67-70 distribution blocks? Would the front and back line seats have to be pulled out?

How is that done if you don't mind me asking?
