Stop my front brake lever screws from vibrating out? One of the most common maintenance tasks on my Mongoose Tyax Super is to tighten a small screw in my front brake level. It shakes loose both due to use, and from a habit I picked up riding in Cambodia, where I "tick tick tick" the level as a subtle alternative to ringing a bell when passing pedestrians. 

I assume that I could use loctite or some tap/adhesive, but I'd still like to be able to remove/clean/replace this screw. I like to adjust it between downhill and commute (I like less travel and more give on downhill). Any tips? Cheap solutions, and retail solutions?
Loctite Blue 242 is a light duty, adjustable, and removable loctite designed for jobs like this one. It will prevent vibration from loosening your screws without preventing the adjustment you need for your brakes.
