Brakes problem
2004 Chevy Astro 6 cyl Two Wheel Drive Automatic 150k miles

When I apply the brakes there is a "honking sound" coming from the brakes. It sounds like a vacuum noise, after that the abs light comes on. I just removed the master cylinder and it appears to be in good condition. How can I tell if the problem is in the master cyl. or the booster? Is it prudent,at this time, to replace both as long as I am this far?
