Instructions (PDF)

Learn more about how adjustable proportioning valves work by reading our tech article. Brake System Selection.  

Note: This is a universal fit and that due to the differences in master cylinder castings, that it's possible the bottom of the master cylinder OR the bracket may require grinding/adjusting to fit the bracket correctly. The lines may need to be "tweaked" to fit correctly and due to the different fittings on master cylinders, adapter fittings may be required as well.

Better read the ''REVIEWS'', i didn't

December 26, 2015
I purchase a master cylinder and this proportioning valve, what a bad product , I wrote a review to tell them about this product , speedway call me, sent me a email , haven't heard back,they should really remove this product, if I wanted to have to drill and make this work I would have went to another brand , ''WISH'' I had read the ''REVIEWS'', I finally mounted the proportioning valve to my frame , and threw away the the chrome bracket, I even paid extra for. which is cheap chrome. I still make purchases from speedway cause they have great pricing on there products , but this one is bad for the Customer.
No, I would not recommend this product.

A few short of a good

November 10, 2015
A few issues: The plate that it is supposed to mount to hits the top of the brake light switch, which the top of it is slightly taller than the actual block for the proportioning valve. I added two thick washers between the two, solving the problem, but it wasn't going to work well out of the box. The supplied input lines were OK, but they are installed so close to the brake light switch and the proportioning valve that a normal tubing wrench is too bulky to fit. A open end wrench does not fit. I had to ruin stubby combination 3/8 wrench by cutting an opening in the box end side for the tubing, and its thin walls were sufficient to allow me to tighten the input lines. The Rear brake output is located on the rear of the valve block, which when installed in a car is extremely awkward to get the line installed. Luckily the wrench I made in prior step helped me with slight angle tweaks to the line I just made to get it lined up to screw in, but it was all by feel. The valve itself says Increase / Decrease and there are no directions. I thought this meant "Increase rear brake" so I adjusted that way. But that is NOT how it works, INCREASE means REDUCE rear brake. Other than those problems, now it seems to working well and solving the problem I had of adding new brake components to an older classic car and having the brakes work properly.
Pros:
  • works
Cons:
  • Rear Out Fitting Hidden
  • In Fittings Location Bad
  • Valve Nomenclature
No, I would not recommend this product.

Nothing fit together

October 04, 2014
The products individually are great, but they come as a kit and NOTHING fits together as it should. The proportioning block doesn't bolt to the bracket. (I had to drill my own holes). The stainless lines won't not line up with the proportioning block and master cyclinder. I have to make new lines now so I can use it. :(
No, I would not recommend this product.

This adjustable proportioning valve would be a great addition to your pedal assembly and disc/drum brake set up. The term combination valve can mean several things depending upon the particular valve. This 91031367 proportioning valve would be a very good choice for you brake system.

Hi, I purchased & just received item 910-31367. 1. The New Proportioning Block has too many Outlets, what fitting do I use to block off the extra port ? 2. The Rear Brake Line in my truck connecting to the old Master Cylinder is a 1/2" flared fitting. 3. What Adapter Fitting do you have that will fit my 1/2" Male Threads Fitting to the 3/8 Port on the New Proportioning Block ?

Plug part number 9103186 can be used to block one of the outlets for the front brakes if needed. Sorry we do not offer an adapter that will allow you to connect your current 1/2" thread brake line to this proportioning block. If your rear brake line is 3/16" OD then you will need to cut the line and remove the 1/2" flare nut so that you can use one of the supplied nuts and double flare the line. If your rear brake line is 1/4" OD then you will need to cut the line to remove the 1/2" flare nut, then use 7/16" flare nut 91031819 and double flare the line. Then you will need adapter 9103183-3/8 in order to connect the 7/16" nut to this block.
