If you have air in brake lines?

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!
