Title: Rear brake light switch troubles
Post by: rkildu on November 13, 2011, 07:58:26 PM

My first post here,  but some of you may recognize me from K11OG site.

I am having frustrating issues with the rear brake light switch.  I went so far as to replace it last winter, but it still hangs.  I tested the old switch with a meter and it's working fine. 

I finally got it to perform in my garage and found that the brass lever arm on the switch seems to be flexing.  What I mean is that the arm is "L" shaped, from a front view, and my pedal pad (bolt?) is pressing on it way out toward the end of the 'foot'.  Apparently sometimes this flex is enough to prevent the micro switch from closing.  The switch itself seems to work.  The only thing I can think of doing is to bend the leg part of the lever arm in to get it closer to the pad (bolt?) center.

Has anyone else encountered this problem?

I am about to start a tear down to lube the clutch splines.  I will try to fix it while I have it apart.  Any other suggestions?

I have not encountered that problem but your fix makes sense to me. And it's cost effective too so what have you got to lose? You could also put something on the "L" to make it thicker.

Hey, rk, How's it going?

What to you mean by closing?  The reason I ask is that when you apply the brakes the switch actually closes the circuit to light the brake light.  Or is your trouble with the switch opening the circuit when you let off and the brake lever returns?

Hey guys,

The problem is that the stop light stays on when the brake is released.  This plays hell with my Kruse Kontrol working and it bugs folks behind me.  I have flashing brake lights.

It's possible to rotate the body of the switch a little when mounting it.  That might help.  Or just bend the arm a little.
