Technically, no, as Ken said.
But, if it needs a fluid change, now's a good time since you start at the back anyway. I bleed brakes by myself. I pour about 2 inches of fresh fluid into a Smart Water bottle (the kind with the flip top lid) to let the hose be submerged and to weight the bottle down. I use some clear hose I bought from Lowe's or Home Depot and stick it into the bottle until the hose reaches the bottom and curves to the side. The hose is a good fit through the bottle's spout. I slip the other end over the bleeder screw, crack it loose, then go slowly push the pedal- no need to pump. I learned that you should NOT push the pedal all the way to the floor. Try to not go any further than you would if you were making an emergency stop. I pump it a few times then quickly go check the hose for air bubbles. I check the reservoir then pump some more. Of course, you start at the right rear. So, you can bleed this one until the fluid in the hose goes from dark (the old fluid) to light (new fluid) and you'd have most of the old stuff out of the system. Move to the left rear and do the same. If your clear hose is long enough, you can position the bottle so that you can see it while you pump. A few times while pumping, I'll turn the key to the "on" position (not crank) to cycle the solenoids in the ABS module. I do this right after I start to push on the pedal. This will push out any air trapped in the ABS valves. It may sound like a lot, but it's really not and I can bleed much faster this way than if I had help because I don't have to keep barking out "Pump!" "Hold!" "Are you pumping?!" "How's the pedal feel?!" "Are you holding?!" "Are you still there?!"
