Leaking master cylinder reservoir

[wapam]

Greetings,

The front MC seems to leak between the reservoir and the metal base. I've taken off the reservoir and cleaned the mating surfaces but it still leaks a little. The rubber o-ring was in good shape. I've tightened the screws as much as I dare.

Thank you.

Did you try a little silicone lube on the o- ring?

Worked for me.
