its very hard for 1 person to do by yourself, the best answer is ask a mechanic at a local garage, they'll show you in 5 minutes for free, or they can do it for 20$-50$,well worth it if something breaks,which always happens on old rusted bleeder valves and lines.let a pro look at it for 5 minutes.
YES!
Replace the brake line, bleed the brake. top up with brake fluid. Done.
Replace and bleed line
replace the brake line and then bleed the brakes
Always best to bleed both sides if you change a brake line. EG: Both front or both rear.
If you have not opened the brake system ie. taken off any lines or lost any fluid, you should not have to bleed a brake system. Brake jobs are best done by experienced technicians.
You can't bleed it any other way, you have to bleed it through the bleeder valve to get all the air out.
replace the line and fill and bleed breaks.
You have to remove the brake line making sure you have something to catch to fluid that will drain out. Plug to the line to prevent the system from draining completely. Remove/replace the brake line and refill the master cylinder reservoir and bleed the air from the system( if it is the hose at the caliper, you usually only need to bleed that wheel). If the reservoir drained completely you would have to run a ABS/bleed system test using a scan tool. After the air is all bleed out, recheck/top off the reservoir.
You probably have air in the brake hydraulic line. Bleed the air out of the brake lines.
To bleed brakes on your 2008 Uplander front and rear, disconnect the brake line at the caliper.
more than likely you have air in brake line and need to bleed brakes
