Sounds like the spring clip that holds the brake light switch has fallen out of place inside the switch housing. Need to disassemble the housing to replace the spring and switch.

Interesting. I didnt realize there was a spring that goes in there as well i thought the lever itself engagrs the button. Would any one have a diagram of how to properly install.

I used a piece of card board super glued to the inside of the lever for the time being. Micky mouse but will do for now.

The brake lights stay bright as tho they are being pressed bon stop. The way the lever works is the it is always pressing a button in the switch houseing until the brake is pressed which then unpresses the button makeing the brake lights bright

My levers are not pressing the button. So the lights stay bright because that button never gets pressed in.

I dont know how to make the lever press the button i must be missing something

Go in here:

The light is activated when the button is released. Since the button is not in the correct spot, the brake lever is not depressing it to close the cicuit, leaving the brake light on.

Here's some info from one of my older posts.
If the v-shaped clip is OK and in place you might have broken off the top of the switch button. To repair this issue, some members reported gluing a piece of plastic to the push button.

If you open up the housing and try to operate the micro switch check if there is a response from the brake/taillight.

The switch is located as shown in image 2 (p/n 2). Try to adjust the switch's position by bending out the wedge.

Here's how the brake activates the switch:

The pin on the lever (see image 1 p/n 1) pushes the plunger into the brake cylinder when squeezed... at the same time the brake switch which is mounted through the hole (image 2 p/n 3) is being released.

Could be the switch has been damaged. When you work on the brake side follow these instructions:

When you want to take off the lever from the handlebar and insert a piece of 4mm cardboard, the lever is pulled in a little allowing the pin to come off the brake switch's rubber cap. Now the lever can be removed without snagging this rubber cap.

When you re-install the lever, insert the cardboard as well and insert the lever as shown in image 3....

Thanks for posting that diagram. I'm computer illiterate in that regard.
