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. Review: Fit a 79 Blazer with no issues - 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.
