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!
When the caliper doesn't slide the outside pad wears quickly, this is the only way I could see the pad coming out of caliper. I have seen a failure when the bonded brake material has come off the steel backer and pad has come out. I have gone to all riveted pads on my trailer for that reason. Napa should have riveted pads (pads from a 1985 Cadillac Deville along with calpier are the same as Kodiak parts). Check the wear on the inside and outside pads to be sure they are wearing the same or close. when I service this style brake I pull rubbers and sliders and make sure they are clean and no debri. make sure to use disc break slide grease on all slider bolts.
