I just recently change the power booster on 97 astro, and the brake lights wont go out..... i figured that i is just air in the line so i went to bleed it and the bleeder port (nipples) are all chewed up. so i put it off figuring it would work itself out. well its been a while now and no change. is it just air or could there be a problem some where..... Thanks.

Depending on what brake lights and what ABS system you have.
If the light is on you have a problem?
A ABS code check would be in order. Post back codes.
Is it 2W or 4W ABS brakes?
