 Kart: the piece on the inner fender you're referring to is called the brake pressure differential switch.
Here's what I wrote in 2012:
Jay, Bob: what Sander has done will not compromise your brake system. The 2 end caps are removed and tapped with a 1/8" tap, around 10-12 turns (this means no fluid from one side will get into the other side, we do not tap the electrical switch outlet--no need to); then we use a brass allen plug putting teflon tape ONLY on the upper threads to ensure no tape will "clog" the fluid lines. We have to retrofit the later switches( '75 and on) since only one end cap can be removed for tapping. I keep a couple of them ready-to-go.

have plenty of the 1/8" brass allen plugs if you need them
