YES!
To bleed brakes on your 2008 Uplander front and rear, disconnect the brake line at the caliper.
replace the brake line and then bleed the brakes
no,not as long as you haven't replaced a hose,line or any thing else that might let air in
If it is a hose, that runs from a hardline to a caliper or from a hard line to the hardline located on the axle, then you simply remove the old one, using a line wrench, install the new one, and bleed the brakes. To bleed the brakes, you start with the wheel farthest from the master cylinder, but if you only replaced one hose, then only bleed that one. If you must replace a line, then remove that line, either have someone or make up a new line yourself, install the new line, and bleed the brakes.

You must remove it, fit a new one and then bleed the brakes to remove the air in the new line.
Always best to bleed both sides if you change a brake line. EG: Both front or both rear.
more than likely you have air in brake line and need to bleed brakes
You may have a collapsed brake hose or a pinched brake line.
someone sits in the car slowly pressing the brake peddle while you have the brake line open. When finished bleeding the brakes, don't forget to refill the master cylinder.
First you disconnect the brake line and place it into a large bowl. While someone is adding fresh brake fluid, press firmly on the brake pedal until all air is gone from the line.
Bleed the brake lines and make sure there is no air in the system.
If the pedal feels soft and spongy, you have air trapped in your brake lines. Did you prime the master cylinder before you installed it? Air in the brake line will not let the fluid fully compress. With all that you changed out, your brakes shoudl feel like new. Read up on how to bleed brakes or take it to a pro.......but don't continue to drive it the way it is.
