Front and rear discs at the min would be about 150.00, rotor work, caliper work, master cyl., vac. boost or hydra boost all cost xtra between 100.00 to 900.00 for complete overhaul entire system. If your van is locking up at little brake pressure its hydra boost. greg
For several years of the Chevy astro van had a power brake and power steering system that was linked together. Instead of a brake booster, the power steering pump provides power to the power brake system. Often, if the brake pedal would become hard to push, it is a power steering pump problem. Change the power steering pump and the power steering fluid and your problem may disappear.

The emergency brake release on a 2010 Chevy Malibu is located beside your left foot. You would push down on the emergency brake pedal to release it while having your right foot on the regular brake.
You either have a bad brake caliper or the brake hose is bad.
I found alot of Astro part at my local junk yard. most in very good shape. The only thing would be getting the correct color.
