Hey! I had this issue with my rear brake light always stuck on. I consulted the service manual to figure it out. Which by the way you can find on this forum via 'home>service manuals'. My brake light switch had already been adjusted fully so that was not an option. After figuring how it worked I just removed the brake light switch spring and re bent the hook 5 mm lower. Works a treat now. I don't know if the front brake works the same though... maybe a similar adjustment can be made... I am interested to find out myself
