The Stovebolt Site Forums The Shop Area General Truck Talk Brakes, have y'all seen this before?

Without spending the time to check the numbers. I will say this.

Gm is and was known for the pictures in the service manuals to not match what is on the truck/cars. this still takes place today.

Even the info on the pages are not always correct.

Here is what can be the case with your truck.

or there is a chance that gm chose to use another type of setup other than what is in your book such as a optional rear end?

Someone should be able to help fill this in.

The way I would figure is what you have shown.. It works fine.

if you can get the kits to rebuild the wheel cyl. than don't replace anything.

If it aint broke than don't fix...
