Slave cylinder and braised pipe connector leak

[UKPhilTR7]

I started up tue tr last night and she started and momd forearms and back again without any issues. Quite smooth and easy. Little harder when the engine was not going, but when it counted it was good. After running and moving her, I pressed the pedal in and the sound was still there.

Going to keep an eye on it for now as the plan is when I do an oil and filter change, to put the speed blender on and bleed it again. The bolts on the cylinder seemed tight enough. Will try putting oil on the spring, it cannot hurt lol.
