85 sierra front brake hose removal

I replaced the front calipers on my 85 gmc sierra pickup 1/2 ton about 2 months ago and the passenger side front still locks up I believe I got to put a new brake hose on but can't seem to find anyone who can tell me how to do this what tools do I need etc. is it difficult to do if someone can tell me how to do it I can step by step if possible.or could it be a bad caliper they sold me?please help

Autozone.com repair guides will have the bleeding procedure and removing the hose is like replacing the caliper you are just unscrewing the hose from the line on the chassis, not a hard job if you did the caliper.

well it looks like to me I need a second person to help unscrew the hose from the chassis and find the right tools tried all I had and none fit doesn't look like a one person job like the calipers were except when I bleed them or I'm I missing something here but got dark out so will look again in the morning figured I had all the normal size wrenches but the one I need is not there if not put the tire back on and take it to a shop but hate to spend that money when I already bought the hose and they don't let you bring your own parts and install them so I'd be stuck with a hose.Autozone doesn't show you how to remove the hose completely
