1)Look for a wet spot where the master cylinder connects to the brake booster. In most cars, this is where the the brake fluid usually leaks. The brake fluid will eat away the paint on the brake booster. If it is wet here, the master cylinder needs replacing. When the master cylinder is removed, you'll see that it is wet (should be dry) where it was connected to the booster. 2)Check all 4 brakes and look for wet spots on the calipers & wheel cylinders. Same things apply here. Replacement might be needed. 3)Check where the brake hoses/lines connect to the brakes.
In a Chevy Cavalier, you put the brake fluid in the brake fluid reservoir located atop the master cylinder. You can find this under the hood, on the drivers side, near the back firewall on top.
