Steve, Thanks for the tip with the helper springs. Mine did not have any on them and I bought it with only 8,300 miles so I'm going to assume it did not come with them. I will contact Meritor and order a set. Thanks again. If one is mechanicly inclined, and can look at the difference the way the front caliper air cans ride as opposed to the rears, you can see that the rear air cans are much larger, heavier and mounted farther inward. This works like a lever pushing out at the bottom and pulling in at the top. It acually took a floor jack and one person to hold it on the floor jack because of the unbalance of the assembly. I was very lucky, I only had to replace both rotors and the pads. To anyone that has this brake system on thier coach I would recommend checking caliper/rotor alignment at least every 6 months.
