I can’t get the lever pull any better no matter how much I bleed them

On these brakes I’ve had for a while. The bite has always been sorta sucky, but no matter how I bleed them it always gets slightly worse.
I’ve tried using a hand vacuum pump (didn’t work)
I’ve tried using a syringe to suck from the bottom and then squeezing the lever (didn’t do anything)
I tried an MTB style lever bleed(obviously didn’t help)
I don’t know what I’m doing wrong, the brakes are new ish with little pad wear, and the rotor is brake new.
Anyone who knows how to bleed brakes please humor me because I’m totally lost here.

Is there a grub screw on the inside of the of the lever near where it pivots? Tighten it up a bit to remove slack at the piston.

That point, probably the brake master cylinder inside the lever is shot and the only fix is to replace the lever with a new one, preferably with a name-brand on.
_DARK_X@reddit (OP)
A new lever or entire master?
MesugakiBratTamer@reddit
Lever, you can't replace the master inside the lever

I’m not sure you can just buy a brake lever like that for these brakes
MesugakiBratTamer@reddit
Is that an ebike or an emoto you got?
_DARK_X@reddit (OP)
An emoto but it didn’t feel right posting this in the motorcycle subreddit and I’ve seen ebikes with similar brakes

I see, then yeah. You would be better off asking the motorcycle sub to see what gives. Many parts used in EVs could also be seen on ICE vehicles, and I believe brakes systems are one of them. I also believe you would be using DOT brake fluid over mineral oil, which electric bicycles use.
I wouldn't be able to help you much, unfortunately

Guess im not motorcycle enough for the motorcycle subreddit and to motorcycle enough for the ebike sub

Don't know what else to tell you. A lot more components are serviceable and replaceable instead of replacing entire assemblies

Theres an adjuster in the lever where you can set when it engages. Look what its set at becasue its common for it to not be adjusted at all.
_DARK_X@reddit (OP)
There’s no adjustments on my lever anywhere. I’ve examined it and it’s literally just a piece of metal pushing into the master

Ok, then its probably broken. Buy one with an adjuster.
