If you have air in your brake lines you must get it out because the air in the line will expand due to the heat comming from the brakes themselves making the brakes contract on their own. If you have your manual it can show you where your bleeder valve is on your brakes and possibly what kind of break fluid is needed for fluid replacement. just remember to bleed the lines while at the same time refill the reservoir so as not to get any more air into your lines. Once the color from your line has changed to the new fluid color your set to go. Caution: There are different ways to different cars so your safest bet is to get a couple extra hands to help and read the section in your owners manual concerning brakes. GOOD LUCK!
Then you need to bleed the brake system to remove the air.
When replacing brake lines, wheel cylinders or calipers air will get into the lines because they were taken apart. Usually air gets into the lines before you work on it because the master cylinder got too low on brake fluid letting air into the lines. Also a bad seal on a caliper piston and a brake wheel cylinder will allow air into the lines.
It sounds like you have air in your brake lines. It sounds like you have air in your brake lines.
Typically brake systems in cars and pickups have brake fluid, not air in the lines. There should never be air in your automotive break line
You Probably have air in your brake lines Or you may have low brake fluid. Mechanics can bleed the brake lines which will remove the air out of the lines. I do not recommend doing this yourself.
Bleed the brake system.

Air in the brake lines
You have to bleed the brake lines because if there is any air in the lines the brakes will fail. If there is any air in the brake line, when you step on the peddle the air will compress and not transfer the energy to the brake caliper or drum and not stop the car.
Air being charged to the brake system. When you pull the brake valve, the air in those lines gets purged. When you release the brakes, it has to refill those lines and chambers.
The service brake is the one which applies the brakes - the emergency brake system is the system which releases the spring brakes.
You probably have air in the brake hydraulic line. Bleed the air out of the brake lines.
