Leaked oil coming from lever pivot pin


Active Member
EBR friends,
I'm new to disk brakes and my Tektro brakes are now both leaking fluid from the area of the lever pivot pin.
One of the leaks is substantial now and has been there since day one, the other started after I bled both brakes the other day.
I've tried googling it but found nothing much.
Any clues to cause and repair?
Thank you.
Do I need something like these?
