Change them now!
Staff Reviewer -
Had to replace all the brake lines on my truck due to rust.I figured while it was apart I would change the hoses,banjo bolts and bleeders as well.The bleeders had practically rotted away,but all but one came out.The other broke off in the caliper(had to replace caliper).Replacing the bleeders when you do brakes is cheap insurance when doing future brake repairs or service.
Bottom Line Yes, I would recommend to a friend
Dorman Brake Bleeder

I like to replace the bleeder screws when I flush the old brake fluid out of the system. Replacing the bleeder screw assures me I can remove it the next time I need to bleed the brakes.
