The curse.
Sadly, mine was defective. I spent 3 hours with this thing, even pulled it back apart and inspected the seals and boar. But could not get it to work, and it would just spit fluid out the top making a huge mess.
Sent it back.
The Blessing.
This gave me the chance to upgrade my 91 C1500 Silverado to a larger, more powerful Duralast NM4073 unit that fixed all of the squishy pedal issues on all of these Chevy trucks. If your curious, just look up “brake master cylinder upgrade gmt 400 88-98 trucks” on youtube. This was a super easy replacement and only needed one adapter to install, and that was a 1/2″ – 20 male thread to 9/16″ – 18 female thread. Ignore the package he mentions, as he says that it was packaged wrong and I ran into the same issue. Just tell the guys at the shop the size adapter you need and your good to go.
I also deleted my garbage abs dump valve, as these go out and will also contribute to your low pedal issues. I now have a better than brand new truck brake system.
The guy who does the above video also does a video on the rear abs delete. It turned out that I didn’t even need the abs delete adapter for mine, as both were the same size.
I wish I had known about this upgrade years ago. I take real good care of my truck, but the brakes were simply garbage, and no amount of new pads, new parts or bleeding would fix this issue. Apparently this is a well known issue for these trucks.
This was by far the simplest upgrade, and all it needed was one adapter and a small bit of line tweeking to make up for the adapter space. My truck now stops on a dime and gives me 9 cents change.
Funny thing was, I was real nervous about doing this in the beginning, but there were actually comments on Amazon for this on the Duralast NM4073 page, and the guy at my Auto zone that helped me, actually did the same upgrade on his truck and loved it.
It’s totally worth the time. Just make sure you bench bleed your master cylinder and only push the plunger in no more than 1″ inch. It takes some time but will bleed out just fine. Never push the plunger in all the way when bleeding.
Good luck!

Perfect fit

Perfect for what I needed. Great quality. Easy installation. Perfect for the do-it-yourselfers
JBE –
No issues, comes with detailed instructions on bench bleeding it before installing. You do not need any special tools to bench bleed it. Screw-in plugs for the brake line sockets would be helpful, but not a necessity. It comes with plugs, but they are not screw-in.

I primed the unit then put it on then bleed the air out and it worked perfectly.
