So it was 71 degrees today. A group of friends and myself took a 250 mile ride which was great. When we were stopping for lunch I hit my front brake and felt a slight change. I couldn't see anything wrong. The brake still had good griping power and the rotor did not get hot. However my buddy noticed as we were almost home that my brake light was on all the time. Any ideas? What would you try?
Sounds like it is something to do with the brake lever. Might have got out of adjustment some how and it's keeping the brake light on but not actually putting any pressure on the master cylinder itself.
There is a small spring behind the lever that keeps the switch in the off pos. Make sure it's there it will add some resistance to the lever. You can check the switch by moving the lever back and forth if it's good you will here a clicking sound.
Sometimes things turn out to be simpler than I would have guessed. This rarely happens for me but today it did. The problem was the brake stop screw under the rear brake peddle. It had backed out causing the switch to remain engaged. So just after the celebration of finding this I went to start my bike for a ride and the battery has died. Oh well. Can't all work out the way we want :-)
