I believe a brake bleeder canister is the easiest one man operation. The canister is partially filled with fluid and attached to the master cylinder. Then you add 6 or 8 LBS. of air pressure to the canister. Just work your way around and in a couple minutes you are done. No telling wifey when to pump and when to release. Happy happy!
I leave the 20psi on overnight. If it remains at 20psi all night, I know there are zero leaks.
As particular as you are Kube I'd bet "dollars to donuts" you have never had a leak! That was just a hint for us normal type guys. LOL And Thanx!
