I have actually had very good success on my 93 (complete flush and bleed) using the autozone one man bleeder kit. Works very well 
and cost something 
like 5 bucks and comes with instructions too!!

What timing! We just had a thread get locked on this... But Speedbleeders do work quite well (URL edited to comply with Forum Rules): they're a checkvalve that replaces the plug on all 4 calipers. So you losen them up and attach a clear plastic tube, then pump the brake pedal until the fluid in the tube is clear and free of bubbles. Tighten them back up and then repeat for all wheels.
Although I have no experience with the Autozone kit - the speedbleeders are $7 each (you'd need 4) and work exceptionally well. Although a few have negative experiences, by and large the consensus on the forum is that they are a great niche product. I had mine 4 days after ordering from the online catalog.
No matter what the method - as there are many ways to skin a cat - just be patient, keep the master cylinder full and repeat as necessary to fully flush the system.

Recently I replaced leaking master cylinder on my 94. I purchased a vacuum pump to bleed since I had to get inside of car to bleed the prime line.
The pump and my shop manual made it the easiest bleeding of a brake system yet.

Speedbleeders worked great for me when I flushed my system recently. It made the job much easier.

I have a question for those who use the mity vac. I too, have the mity vac, but when trying to bleed with it, it seems to suck air from around the bleeder threads. Is there a way to make this an airtight fitting? Is there something obvious I am doing wrong?

I just open the bleeders and let gravity bleed the line. Only do one at a time and take your time, when fluid starts running clean just close the bleeder. Never had any trouble with getting air in system. It is a slow process but works fine.

By the way - I used my speedbleeders along with the clear tubing and catch bag yesterday. I was able to completely flush the system by actually seeing the new, clear fluid squirt into the catch bag (my old fluid was dark/black in color). Worked like a charm I was also able to verify the airbubbles in the clear tubing and watch them as they were pumped out. For my situation, one full pedal movement pushed fluid approximately one-half the length of the tubing I was using. Easy to check up on the one wheel I couldn't watch (right rear).

I tried the MightyVac with limited success. I have heard that it can cause air bubbles in the caliper, similar to what you are seeing around the bleeder screw. Apparently because you apply pressure at the bleeder and suck the fluid through. The Motiv pushes it through.
Just pump the pedal a few times before you hook anything up to get the air out of the PB booster. Attach Motiv PB with 1qt of brake fluid and set to 10-15lbs. Bleed away...
Easiest method so far on both my C4 and C5 is get the whole car on jack stands. Pull all 4 wheels. Follow the bleed order for your car. Go around the car twice. Second time just blled off a little to make sure it is still clear and free of air bubbles.
