You shouldn't need to pump the pedal but any movement will dislodge air bubbles..
Watch the mess as the master cylinder over flows.
This has always been a quicker, better way for me to bleed systems.

You need a vacuum bleeder to do a good job and take the unit off the rear swing arm and make sure the air moves up to the bleed screw. Bleed the master as well. Even fully bled the system is slightly mushy on the rear brakes.
I was having difficulty bleeding the rear brakes on my WR after replacing the brake switch on the master cylinder. What I did was remove the caliper from the swing arm and zip tie it up with the muffler. I then went through the normal bleeding process and was finally able to get the trapped air out of it.

Another option:Open the top of the master cylinder,get a syringe, fill it with brake fluid, attach a hose between the fluid and the rear caliper bleed nut, open the nut and reverse the flow of brake fluid, add fluid until the bubbles stop...
This was the only way I could get the pedal to "firm up" & start actuating the caliper when I swapped out my rear line.
