Do you have to bleed the brake lines when changing brake pads on ABS models??

This is on a 99 GMC sierra 2500. I%26#039;ve changed brake pads before but not on one with ABS. It says to bleed the lines when depressing the caliper piston do I have to????





Thanks.|||no you are going to be ok you dont have to bleed the system unless you open the system up to replace a caliper or brake hose
