Re-reading my original post, I guess I wasn't real clear about what's going on. It's not so much of a problem with the outer pad wearing quickly, it's completely missing! Or is that what happens when the caliper doesn't move? When I removed the caliper it slid very easily on the bolts and bushings.

The hoses do seem to be long enough. Have a little play in them and not being stretched.

It's a 3 car, 36' stacker. 3 8000lb 8 lug axles. It's close on weight. Have 23,400 on the axles.

Thanks again for your help!
