    You need a hose (clear so you can see the air bubbles and new fluid) to put over the bleeder valve so the bleeder doesn't suck air back in.
    Start with the wheel farthest from the MC, so the passenger rear wheel.
    Put the hose over the bleeder, open valve, and have your friend pump the pedal 12 times.
    On the 12th pump have them hold the pedal down then close the valve.
    Repeat for all wheels in the order of:
    Passenger rear
    Driver rear
    Passenger front
    Driver front

    Make sure to check the fluid reservoir and add fluid after every wheel so you dont starve the lines.

    As for the clutch.
    Put the hose on the bleeder vlave, open the valve and have your friend pump the clutch until you see fresh fluid coming through the hose. Have your friend hold down on the pedal and close the valve, then they can let off.
    Keep in mind that no matter how many times you pump the clutch it will stay on the floor, this is supposed to happen.
    All you have to do from there is simply keep pumping the clutch up and down until it regains pressure.

    Thats how I've always done it and it never gave me problems.
    One question though. Did you wet (fill with fluid) the cylinders before install? Doing so will make it easier to bleed after install. Hope this helps OP!! Good luck, man!

      I hate bleeding brakes, these help. I have them on both of my track cars.

          Both rears, the fluid seems to come out much more, front both much less but steady with no bubbles...

          After that i pump few times, brake paddle feels pretty firm, then as soon as i start the car it becomes super light and brakes dont work much... if i press really fast it feels like it would get harder and car almost chokes...

          brake booster? but it pumps fluid thru?

          I will buy power bleeder, just thought someone close by have one...
          it feels like the engine is choking when you are using the brakes?

            That is the brake booster. You got a vacuum leak somewhere.. Could be a bad booster (torn diaphragm perhaps?) or maybe the line/connection to it is rubbing somewhere? Make sure it's not dried or cracked somewhere.

            When there is no vacuum, the brakes will be harder to push to begin with. As soon as you start the car, the pedal will get light like you said.

            Could have leaky seal from the piston seal in the MC to the Booster.

            I haven't seen this issue on BMW's as much as I used to see on GM products.

              I have always had great results
              using a power bleeder and or gravity.
              do all my cars and motorcycles this way.
              I use the power bleeder if need be to start the flow. Then i just let gravity pull the fluid thru, keeping an eye on the fluid level in the MC.
              of course i use a tube into a container to collect the fluid.

                Don't buy Den ... I have one. I do believe SpiDmang has it ... Let me know by PM if you'd like to borrow it. I consider it fair trade for when you lent me your hoist.
