1997 Chevy Astro 6 cyl All Wheel Drive Automatic 110000 miles
My Astro's brakes have an odd, but intermittent problem. Occasionally when I try to stop, they will make a groaning sound and I can feel the pedal push back against my foot and the van doesn't want to stop. If I continue to push on the pedal, you can hear a thump and then the van will stop short. A couple of times when this has happened, the pedal went all the way to the floor, the brakes released and the van started forward more quickly as the idle speed kicked in. I've replaced the pads, rotors and calipers as well as bled the lines. Do I need a new master cylinder or sensors, or what?
