Q:

I have a 1983 s 10 blazer that i converted to rear discs. My existing proportioning valve has two ports in and two ports out. Can I just plug one of the outlets on this proportioning valve?

Asked by on July 17, 2017

A:

I believe you can. It's 1 out for rear and 2 for front

Q:

Will this work if you have front disk brakes already and convert rear drums to disk brakes.

Asked by on June 29, 2017

A:

Yes, this valve is designed to be able to support rear disk brakes. We put if on a 97 GMC Suburban that we have converted to a Cummins 12 valve diesel engine and GM 6L80 transmission. We removed the ABS since they work marginally well and replaced that with this p[roportioning valve. We still have the rear drum brakes on the vehicle but our next portion of this project is to either replace the rear axle with one from a late model Escalade with disc brakes or put rear disk brakes on the current axle and that is why we used the valve that will support rear disk brakes. The Summit site says it will support rear disc brakes.

Q:

What is the proportioning reduction on this valve front to rear?

Asked by DERREK on January 01, 2018

A:

A proportioning valve regulates brake line pressure distributing more pressure to the front brakes where 65% of a car's braking power is. This type of valve was used on GM cars when disc breaks first came out (mid/late 60s). The valve was needed because disc brakes require more brake line pressure then drum brakes anyway.

Q:

I am doin a rear disc conversion on a 86 Monte Carlo ss will this work without any other modifications

Asked by GARY on June 23, 2018

A:

Thank you for your question. The SUM-760185 proportioning valve will work well with your 4-wheel disc configuration. You may need to modify the fitting or line size depending on your stock configuration.

Does not fit 1991 Pontiac Firebird!

Summit RacingSummit Racing Verified Purchase

SUM-760185
What ever you do don't buy this as a replacement as I did for my 91 Firebird. It doesn't fit even though the Summit application list say's it does! All the fittings are of the double (trumpet type) fitting and the 91 car has the single (bubble) type fittings. The rear brake pipe fitting is also in completely the wrong place for our cars. It just doesn't fit period. ...read more

Works better than expected

SUM-760185
I have an '86 Grand National and I did a rear drum to wilwood 4 piston disk brakes conversion. This valve was an exact replacement for my factory one and I was able to use all of the same, stock fittings. After I replaced my rear brakes, I drove the car home on the stock valve which is not made for rear disks since it holds about 10 pounds of residual pressure, and I found that my car did stop a lot better in the rear than before. I am not sure if my stock valve had some sort of a blockage issue, but once I installed this valve from summit, no exaggeration, my braking performance increased by about 300%, mostly in the front. I can hammer the brakes and the car stops like I never thought possible without locking up the rear, even without abs on 4 piston wilwoods. ...read more
