UTSAUTO Brass PV4 Brake Proportioning Valve Disc/Disc Brake System Combination Valve

Fit perfectly.

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.

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.

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...

Did a disc swap on my jeep and this valve really worked out of the box. I fortunately had no leaks so some have had leaks, I'd say order this part and try it.

Universal proportioning valve works well , i recommend making sure you get the connector that fits the one sensor it is a universal so dodge and chevy factory connections wont work found out the hard way took an extra week to get the plug.

Fit well looks good ... Good price

Great for my 84 Chevy truck.

Did not come with accessories needed and couldn’t get them then did not know how to send back

This proportional valve is just what I need to complete my brake system on my project. I'd like to thank UTSAUTO for providing great service and fast shipping.

Installed in my truck and the unit was tripped making it useless to the rear brakes. Do not buy this piece.

The add says it is multi fit part and would work on my truck and it doesn’t
