Please see Questions and Answers for some topics that frequently appear on this board. As you can see, this board loads rather slowly. If you are posting something for sale, please remember to include your location since someone who might otherwise be interested might not be able to use a part or a vehicle that is too far away. Posting your location when you're selling something that needs to be hauled will save everyone's time (and reduce the number of posts on this already too-slow message board). Thanks.

The switches do go bad,
Replacement switches are readily available,
And yes, some brake fluid will dribble out the hole when you remove the old switch. It will not drain your master cylinder, however, unless you step on the brake pedal while you have the switch removed.
After you've made the swap, check your brake fluid, add fluid if necessary, and bleed the brakes.
Remember, do not overfill your master cylinder. I chased a non existent leak for six months because I kept over-filling the master cylinder. It would run down the side and collect in droplets on the brass "Y" fitting.
Good luck!

: I believe the brake light switch on my master cylinder might be bad.

: Will removing the old switch drain the master cylinder?

: I'm new to these beasts and my manual doesn't say anything related to this. It just says something to the effect of "...replace if necessary..."

: Just want to make sure I'm prepared for some brake bleeding if need be.
