There's a reason it's sealed - it keeps water & everything else out of the fluid,
and the fluid in the reservoir. Cutting a hole in it is like cutting out the floor to
let a rain leak drain. If you have a leaky slave, fix the problem - don't create
a new one to mask it.
I've always had a can over the lid so rain don't get in its little vent hole.
But that brings up the next question.
What rain? LOL :)
As far as fixing the slave that's been planned to do for almost a year along
with replacing the bearings and a few gears (including their synchro sleeves)
in the ZF. I got the new slave and ZF parts that long ago.
Looking like it's gonna have to wait another few months and got tired of
adding brake fluid almost every time we drove it so made it, so, now only
have to add it every few times we drive it and it's now more convenient
to add the fluid to, since that rubber baffle/seal don't have to be removed
first. The wife's not complaining about the new setup, so why should you,
The slave is toast.
The master is cheap and easy to replace if it gets damaged by dirt.
(got an extra anyway)
So what's there to protect at this point? :)

ps- Oh BTW, I -drilled-holes- in the floor to let the rain out! LOL :)
Did that in the bed of my '75 F150 when I first got it, drilled my
dune buggies (that had a floor) and drilled holes in the groove
under the plastic threshold on the Bronco. Anymore questions? ;)
