Interesting, I was checking to see why neither my front or rear brakes light up the brake light and then I find this thread at the top of the 660cc discussion.
In my case, I detached the wires front and rear and in each case touching the leads together lights up the rear bulb so unfortunately it's not the cheap
So, I figure both front and rear brake switches have gone bad. What are the odds? When i press down each lever, the switch does not seem to close, so I guess I need new switches front and rear.
What can cause these things to go? They look like sealed units to me, no place for dirt to enter.
Anyway, this discussion seems to suggest the rear one I can get at any automotive shop, but the front one is a BMW part (and there is no BMW dealer around here). Any other alternatives for the front, which looks to me, to be a kind of twist-screw type.
