1999 Chevy Astro 6 cyl Two Wheel Drive Automatic 127986 miles
Brakes squeal or squeak while I am driving and stop when I hit the brakes or when I am at a stop or just idling. When It is cold or wet it also stops as well. At first it was just a faint sound, almost a knocking sound so I thought it was a muffler problem but then it turned into a squeaking that grew louder and louder over time. What is happening?
