Question about 1993 Oldsmobile Achieva
What else should we look for?
Try bleeding the brakes .When you pressed the caliper pucks in did you remove some brake fluid first? Check fluid level.

SOURCE: spongy brakes
I have had the parts stores give me the wrong pads for these before but also these have a little *** or bump on the back of the pad. this bump has to be in the right position or it can cause the caliper/piston not to seat properly. you may have to disassemble and look carefully for this problem. sometimes the caliper won't sit flat on the pad on the outside because of that little ***. also it can be under the piston. just get rid of the *** if you see it and reassemble. make sure you bleed from all the bleeders not at the closest line that comes free.

You need to bleed the brake system. To bleed the hydraulic brakes; you fill the reservoir, with brake fluid then,go to the farthest.cylinder,find the bleed plug(near the wheel cylinder, looks like a grease fitting) slip a hose tightly over the fitting, submerge the other end in a container of brake fluid,then loosen the fitting; (with a helper., slowly pressing the brake peddle down);fluid will come out to the container,if air bubbles,close the fitting at the end of flow then let up on brake peddle,do this till all air bubbles are gone, then go to next wheel cylinder repeat till all cylinder are bled(be sure all bleed fittings are re-tightened,when done. Good luck and keep me posted, be glad to answer any questions you may have.

You may have a leak in the booster or master cylinder. You can put a pressure tester on the system to test for leaks. It does sound like you have an air leak.
You can try to bleed the master cylinder, then slave cylinder, then brake lines.
