Rear brake

[dan twomey]

Is there a brake light switch on the rear brake pedal?  I noticed today that my brake lights don't come on when I'm using the rear brake only.  3rd gen Magna by the way.

Yes,

Most are attached with a spring to the switch. You can normally adjust the switch up or down so your brake light will work when the pedal is pressed.

Now go check it out!

Yes, there is a switch. It is attached to the frame member just behind -- inboard, that is -- where the passenger's right footpeg is attached. It connects to the rear brake linkage through a coil spring.

Hmmm. I will check it out and let you know what I find.  My rear brake pedal has a lot of travel so I'm surpirsed it's not working.

Those switches are not the best engineered pieces of electrical equipment. Many times they will be corroded or have have gunk/grime in them. You can lube a little though not much help for the long run but give it a try.

I agree on design. It is  not an easy adjustment getting it back in the proper tension/adjustment. It is more trial and error Dan.

They do come apart not that hard small screwdriver and yep they corrode in there mine was pretty bad sanded it down and it works like a charm .

I found that it works, I just need to reajust it.  I'll figure that out while I have it on the lift, changing the oil, coolant and fork seals.

Thanks for the tips guys!  I spent 15 minutes spinning that little plastic collar back and forth and then back again. Like new again.   

I've linked the issue back to when I put a new chain and sprockets on last year.  The difference between the new and old chain was well more than an inch and now I recall that I had to readjust the rear brake when I changed the chain and never thought about the rear brake light switch.
