Front calipers not releasing

Thats not the intended purpose of that tool and will not wok for bleeding brakes as far as I am concerned. It's use is to lock the brakes while measuring caster. Works for checking brake lights too. Brake bleeding? Nope
Been doing it with a similar tool i made. Works just fine. I have had some real winners help me bleed brakes and this one does what it is told.

i do auto repairs for a living, working out of my home shop.cant always rely on someone to stop in and assist me. Some of the newer cars require a scan tool to initiate the bleeding process, no pedal jockey required.
