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.
Ho do you replace a master cylinder in a 1989 Winnebago Superchief?
You buy a non abs booster and master cylinder, bolt them in, and bleed the system.
What cylinder? Master (brake) cylinder? Rear Brake cylinder? Lock cylinder?

answerchange master cylinder and slave properly then bleed the system properly.

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.
Did anybody bleed the brake lines? There is possibly still air trapped in lines and air compresses brake fluid does not.
They are all pretty much the same, there is a bleeder relief on the slave, have someone pump and hold the master, you release pressure at the slave then tighten again ( make sure they keep pressure on the pedal ) then repeat until no more air comes out, if the fluid is dirty keep going until it runs clean, you will need to keep adding fresh fluid at the master as you go, dont let it run out or you have to start all over again.
