Ok.. they work fine. It my brake lever. When i push it down, it stays down. I have no idea why, and it wears down my brakes in the back while riding if i forget to kick it up. Whn i press it down with my foot, it stays down untill it is brought up manually. What is wrong? Thx.

 

sounds like the pedal is stuck on the shaft alittle. remove it and relube it .
or you lost the pedal return spring that brings it back.
theres 2 springs on it 1 for the brake light and 1 for the pedal return
good luck

 

Check your return spring on the pedal. Make sure it's still attatched and make sure the tension is good.
