Jeff/Diane,
We had a similar experience when we first bought our 2000 PAT. We had a pre purchase inspection at a Cat Dealer in Missoula, Mt. We were told that the front brakes needed to be be replaced. The Cat dealer tried to find parts and failed.
We talked to Ken at BCS and he knew the parts needed and had them on the shelve. But there are many variables, the serial numbers on the parts is the best way to go.
But we couldn't wait the shipping time and our confidence in the Missoula Cat dealer getting low. So we brought the rig to California and to Sacramento Truck, they have a Coach Service Division, they knew about the recall and had the correct parts.
Sac Truck told us we had less then 10% brakes left, if I knew that in Montana I would have stayed in Mossoula and waited for the parts.
Sacramento Truck works on Cat motors and they are a Freightliner service center too. They do Quality work.
If you take to a shop, make sure they have the experience.
Good luck,
Bill
