Will this power bleeding without special tool work?
Open the bleed valve, Have a friend push the brake to the floor, hold it there!!!
Collect all the old fluid. As soon as fluid flow slows down, close the bleed vale.
Have your friend pump the brake a few times.
Repeat above for all wheels till fresh fluid comes out.
Keep adding "Dot X" fluid so reservoir doesn't run dry.

PS: You probably need to have key to position 2.
