I need to change out the brakes hoses front right and front left in a 86 chev 1/2 ton with a 350 and also the pit arm assembly needs changed and how hard is it to change these items out can i do it my self
Re: Bake hoses and the pit arm assembly needs changed
Pitman arm assembly isnt hard with the right puller for the job.Brake lines need a double flare tool involved if doing it with only steel line and connections.Local auto part stores have made up lines that would work if you had the lengths you needed.Be sure to bleed the system well after fixing starting with longest line first.

start at the furtherest bleeder away from your master cylinder,bleed untill no air from each one move on to next further.that should be right rear-left rear-right front-left front.just keep an eye on the fluid between wheels.hope the booster was your problem and this helps
change the caliper and the hose new brake pads and make sure to cut or replace the rotors everytime you change brake pads ! do not do brakes without cutting or replacing the rotors please ! hope this helps
the only thing i can see you would have a problem with is the pitmen arm, for that you will need a special tool for that, it can be rented at autozone or someplace like that. Be aware they can be a bear to get off. you might be further ahead to have a shop do that for you, and you can do the lines.
The break hoses are fairly easy if they come loose from the hard line, the thing to do is to get some good penatrating oil lik PB blaster and spray the fittings where the rubber end meats the hard end and let it set for a while so it can penatrate, you will also need line wrenches as to not round off the fittings. its up to you if you want to tackel this project or not. This at least give you an idea what your up agenst.
The Quickest way to fix this is to Replace that Caliper. If you don't have the Dough right Now----Take the Caliper off, and Compress the Cylinder Back into the Caliper While Turning the Bleeder Valve Slowly, When no more Brake fluid Comes out of the Bleeder Valve Tighten Back and Reinstall the Caliper and Pump the Brake Pedal to ReSeat the Cylinder. Sometimes this works on the Chevy Trucks!
You say that you have changed the brakes, but did you change the calipers and rotors? I would also look at the wheel bearings to see what condition they are in. The other thing I would look at would be the proportioning valve and the master cylinder.
