- These PV4 combination-proportioning valves are based on the popular AC DELCO 172-1361(disc-disc) valves.
- This PV4 proportioning valve great fit for your classic truck.They will work on nearly all vehicles that have disc brakes in the front and disc brakes in the rear.
- The perfect compliment to your disc/disc brake setup. This proportioning valve (also known as a combination valve) helps proportion the amount of pressure sent to the front and rear brakes, helping prevent rear lock-up.
- Please note that this valve has (2) 3/8-24" ports for the front left and right calipers and (1) 9/16-18" port for the rear brakes.
- The connections from the Master Cylinder are 1/2"-20 and 7/16"-24.

So far so good. Replaced a summit racing brand one that was leaking past the rear port seals.

Did a 4 wheel disc conversion on my Camaro. This valve is well built and very heavy for such a small part. Brakes function well now.

Did a disc brakes on the rear of my 1991 GMC V3500 and this improved braking substantially, this is exactly what you need if you're doing the conversion too.

It bolted right up to the frame and brake lines a 79 Blazer system and worked perfectly.I converted the rear axle to a 14 bolt and converted it to disc brakes. I’ve been using the El Dorado rear disc brakes with the stock disc/drum proportioning valve with a Corvette disc/disc MC and the system worked. I always felt the brakes were lacking and spongy. I didn’t know what I didn’t know is spot on.I’m amazed at the difference in braking. The brake system is so much more responsive.If you’ve done a rear axle swap and converted to disc rear brakes, buy the Corvette disc/disc MC and this valve. You’ll be very happy with the decision.I was a very reluctant to buy this based on the reviews. I was very concerned that I was going to get a problem part. After installation, I remembered a quote I heard. Just because it’s new does not mean it’s a working part. With any manufacturing process, there are going to be problems. Maybe this brand has more than others, I don’t know, but it worked great for me and I’m happy with the purchase.I’ve been driving with this in place on and off-road for a few weeks now. Best money I’ve spent to bring the brakes back to what feels like factory new.

Was as described, havent gotten to see how it performs yet. Bolted right up to an 81 gmc k20 that originally had front disc/rear drum. Put a set of discs on rear with jb7 calipers so we shall see if it does what i need in the near future...happy with purchase. Oh and all the brakelines fit where they should and the brake light wire also fit as it should....someone else said it didnt fit, but it did on mine...

All research I did on this combination valve said all fittings were proper size for my application. Rear brake input fitting is one size too big, is 7/16- 20, needs to be 3/8-24. Will need to find or make an adapter to make work.

Used in my 86 K5 with 1 tons and discs front and rear. No modifications necessary. Bolted right in and got rid of the "spongey" pedal feel. Brake bias front and rear is just about perfect. Have several thousand miles with it installed and no complaints. Not much else needs to be said. Good product, fast shipping.
