There will be no play with the way you set it up. Also remember how much cast iron is in those. After you get it on the road and use them they will heat and have a preload on the bearings. As you know that heat stays in them for a long, long time. Thats why GM wrote it up that way in the dealer service disk. I have a dealer interactive service disk on a computer in my shop. Just enter the Vin number on a vehicle and it pulls up the as built service for that vehicle.
I am sure you will find the brakes (after a bit of use) to be far better than before. I have got on mine hard enough to know that the ABS works from 60 mph to a stop. Missing 3 elk standing in the road right after a corner. Like all elk they just stayed there until I got it stopped.
Let us know how it goes..

We took the motorhome out early Sunday morning to bed the new rotors and pads. It was quite dramatic the difference in braking. Initially needed a lot of peddle pressure but after we did some 45 to 15mph stops and then some 55 to 20mph aggressive stops the brakes were smooth and stopped us much faster with less peddle pressure than before. It definitely takes a bit of peddle pressure but not like before we put new brakes on.
I jacked up the rear of the motorhome and checked the adjustment of the rear drum brakes. They are adjusted correctly. Now I am a little puzzled. This may just be the way it works, but I don't like it. With 4 tires on the back and lots of weight there also, I believe that we should have more braking from the rear.
Snowdance it looks like we have basically the same Motorhome, just different manufacturers (23ft, rear kitchen, chevy, rear drum brakes, front disks). I just have a larger engine (8.1 liter). Where you get around 10mpg I get around 9mpg (8.5 to 9.5). I also drive very conservatively just have more engine than is needed for the smaller motorhome. If your motorhome's brakes do ok....then I think it is what it is and I need to move on.
It was a interesting learning experience.

I agree with you, with so much weight and 4 tires in back, you would think Ford and GM would put monster brakes back there along with rear ABS to maintain good control. I have rear ABS with rear disk brakes on my newer 2007 rig, but the disks and pads are smaller than the fronts.
Regarding "Testing" of your new front brakes. Go easy on them as it will take some use for the new pads to seat properly to the new rotors. There is a break-in period, generally of a few hundred miles pending the vehicle. You don't want to ruin the work you just completed, making hot spots that might warp the new rotors.

Glad to hear you brakes are working well. Always a good feeling to know you have done a good job. They should get better in a while. But you are right they do not stop you like a car. My rear seem to stay adjusted too.I also agree the rear do not seem like much but I have found over time they do the job fine. Perhaps like the front they just had some rust ect.. Be sure to keep the parking brake cable lubed and free.
Got your pm.. We sure do have a lot in common. Even to the lay out in the rigs. We are on the Oregon coast often. Perhaps we can meet some time. Will pm you tomorrow.
