years ago, I bought a "1 man bleeder" tool. It is kind of tubular pogo stick like contraption with a flat collar that locks in any place along the tube so that it will push down on the brake pedal and hold when the collar is propped against the front of the front seat bolster. As I recall it wasn't that expensive but it did require a lot of up & down on my part. I was much younger then, hahaha.
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
oh, it works ok, but it is much. much easier to just grab a friend, or relative, even a kid to work the brake pedal. I've never tried a mity vac, so I don't know how easy that is to use.
Glad it works for you. Mity vac sucks. LOL
The way I see it, compared to a human, is that there is no "follow through" kind of like a bunt in baseball. Kinda sorta works but no real hit.
When you push the caliper piston away from the rotor it will take a significant amount of pedal travel to move the caliper pistons back into operating condition. The drag on the rotor can be significant in a static environment.
If the brake pedal is firm, I would say not. The O ring in the brake caliper is square, if that makes sense. When you apply the brakes, that "square" O ring rocks a little. When you let off of the brake, that "square" O ring un-rocks a little. That is what relieves the brake pressure from the rotor. Not much movement to say the least. Add in some dynamics and wheel bearing clearance, now we have a lot less drag.
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.
careful, burn your fingers if they are dragging.
notice I said touch the wheels not the rotors/drums.
