Leak under brake reservoir

I went to see 10+ K11's to buy today, only one 2 did not have evidence of a leak under the brake reservoir (towards the power steering fluid reservoir).

Is this a common "known" issue, and does it have an easy (cheap :p) fix?

Just to be more detailed, the fluid seems to be coming off the pipe going to the power steering reservoir, but gunking up under the brake fluid reservoir.
