I believe the rear brakes are bled using the ignition switch, and the front are bled the traditional way.
It is important to bleed a clutch master and slave cylinder to make sure all of the air is out of the lines. For a 1989 Chevy you would need to know model you had, and then find the repair manual for that specific vehicle.

You buy a non abs booster and master cylinder, bolt them in, and bleed the system.
To bleed the brakes on a 1989 Lincoln Mark VII LSC, start by ensuring the vehicle is securely elevated and the wheels are removed if necessary. Begin at the wheel farthest from the master cylinder, typically the passenger side rear, and work your way to the closest, which is the driver side front. Use a brake bleeder wrench to open the bleeder valve while a helper presses the brake pedal, then close the valve before the pedal is released. Repeat this process until clear, bubble-free brake fluid flows from the bleeder, and make sure to regularly check the master cylinder fluid level throughout the process.

To bleed or replace the slave cylinder on a 1989 Ford F-150 4x4, first, ensure the vehicle is securely lifted and supported. If replacing, disconnect the hydraulic line from the slave cylinder and remove the mounting bolts to take it out. To bleed the new or existing slave cylinder, fill the clutch master cylinder with fluid, then have someone press the clutch pedal while you open the bleeder valve on the slave cylinder, allowing air and old fluid to escape. Close the valve before the pedal is released, and repeat until no air bubbles appear.

There is a bleeder valve on the front of the clutch slave cylinder right next to the line running in. You pump the clutch a little and then you hold it to the floor while someone opens the valve and it spits the fluid out then you close it and repeat until it has no air in it and the clutch is tight. If it is for the brakes the bleeder valves are on all the brakes and you do it the same way with all four starting with the brake farthest from the brake master cylinder and work your way closest to the master cylinder. That is how you do it.
