P32 sticking rear caliper

Mechanic couldn't find anything wrong. I did fill up the hydroboost resevoir that was on cold fill when hot. He thinks that caused it. I think it is the hoses. I'm going to replace them when I get back.

Where can I order a set of aftermarket brake hoses? He says he can't get them. I checked an Autozone and I know they can't order them.

I found my front hoses at Napa and rear at Orielly's. I found I can find more parts if you tell the clerk Chevy P-30 chassis and the year. I would completely disassemble the rear brakes and remove all rust with a wire wheel use the hi temp silicone grease to lube and reassemble. I just gravity drain my fluid by jacking the front up and allowing the old fluid to drain out installing new fluid when the reservoir is almost empty. When the fluid comes out clear I bleed the drivers side rear next then go to the passenger front then drivers side front. Beside the hose and sticking caliper slide it could also be the rubber seal/ around the caliper piston not returning the piston for clearance causing the brakes to drag. I know your mechanic said it looked good to him and it could have been just a rusted caliper slide that you freed up by use, but I would at least drive it locally step on the brake many times and see if that caliper is hotter than the others before I took it on a long trip.
