Review on Motive Products - 0115 Late GM Plastic MC 💪 Power Bleeder: Boost Efficiency and Simplicity in Brake System Maintenance by William Hood

If you have the white plastic container shown in the picture you can use this brake bleeder. It's not perfect, and it's not as fast as adapters that screw on. Before installing, apply a thin coat of petroleum jelly to the rim of the tank where the adapter plate meets. First you need the 6" clamp that others have recommended (it goes right in the middle), if not two (better) slightly pressed (if using a 6" clamp) on each side if you use one of the ones provided Clamps use chains and J-bolts, wing nuts etc. Press lightly again. Before adding brake fluid to the hydraulic reservoir, be sure to hold the pressure, pump it up to 5psi and observe for 5 minutes. If yes, add liquid and continue. This pressure tank pump unit is pretty flimsy, taking at least 5 minutes of frantic pumping (she said) to get it up to 10psi. If you have that white plastic rectangular container, when you get to about that pressure, the plastic will bend or curve outward, losing pressure and seeping into the engine compartment. Just go to 9 psi and leave it. It's functional and will work reasonably well, but requires a lot of tweaking. Still better than a two man process when bleeding those troublesome GM brakes. Hope that helps.
