Got a small kink while cable routing my new brakes. I unkinked it but is this a problem? Will it be fine like this?

I think kinks in hydraulic brake hoses are dangerous. I know on motorcycle it is a no go, it can prevent the brake pistons to return because the liquid is not able to come back up. In other word, it can keep your brakes (partially) engaged after you release the brakes. I would replace the hose be safe.

That’s not a small kink.
