Will any proportioning valve work? 1965

Postby whitecastle » Fri May 17, 2013 11:20 am

It's with shame that I just now make good on a two year old post about upgrading my MC. :oops:

I understand my 65 has a metering valve. It leaks. I have a Dual M/C I really should install, so need a proportioning valve.

Is there anything I'm looking for specifically? These are the three available to me in town.

I presume any will work, or is there a key difference between a Disc/Disc valve and a Disc/Drum?

Yes - I will add speed bleeders too.

The answer is: yes, any adjustable proportioning valve will work.

You will have to do some road testing to find the highest point of pressure below which the brakes do not lock. So just set it, go for a drive and do a really hard stop. If the rears lock up, adjust the valve down. If they lock up too much on wet road, go a little lower.

Your 65 has a metering valve AND a proportioning valve.

The metering valve is this one:

The proportioning valve is this one:

You need both. The metering valve helps reduce disc and pad wear by setting the minimum pressure at which the front brakes apply. The proportioning valve does the opposite and sets the maximum pressure at which the rear brakes are applied.

I just bought a combination metering/proportioning valve from Lincoln Land. $145.00. I am on the final stage of replacing the whole system. The combo valve may also be available from NPD. It looks the same. More information when I finish and STOP!!!

So just to confirm:
A combination proportioning valve replaces both the stock prop valve AND the stock metering valve?

Doesn't look like any of the above options will work then, as they are simply adjustable prop valves. Sounds like I'm looking for a combination proportioning valve (not sure if they are adjustable or not).

I finished the job. Installed new rotors, callipers, pads, hoses front and rear, master cylinder, rear wheel cylinders, and the combo valve. It is not adjustable. The car stops fine.

Yes. You want a combination valve. You may have to look for an NOS or used valve from a later model if you want to find one.

The industry doesn't talk about the metering valve much anymore. New caliper designs may have eliminated i's need from modern cars, but I'm not sure.

They may have just been merged into the computerized anti-brake systems so don't get as much attention as they should.

I don't know why, but the '67 setup is reversed, according to the manual. The metering valve is in the rear brake lines, and the proportioning valve in the front. Whatever, I was in dire need of a front valve for years. Finally got one last year, retrofitted it, and the difference in braking was amazing. Also amazing, the rotors stopped warping grooves in the edges. Wish that had occurred to me back in 2004.

Thanks Dan.

This is the one I think I'm going to use: Wilwood Combination Proportioning Valve
