Last week, when I came home from picking up my kids with my Nissan I realised all brake lights weren't shutting down. I was kinda in a panic mood because I thought some wiring when crazy.
Thanks to the nice people at forum on the web they told me it might be a brake pedal rubber stopper that had broke so I went back to the car and found broken bits and pieces of rubber on the carpet and I am kinda relief it was only a $2.00 rubber stopper.
I drove to a local parts center, A&W Parts, to find the replacement. Unfortunately they don't have those but the lady boss was kind enough to let me take a set of Nissan Primera brake pedal that still has a good condition brake stopper.
That bright green button is the brake stopper. How does it work? Every time you press your brake pedal, the green brake stopper will be push away from the "brake light switch" hence switching on all your brake lights. When you release you brake pedal, the green brake stopper will return to touching the brake switch again to shut down all the brake lights.
To remove the green brake stopper all you need to do is pour the rubber with hot water for several seconds. Then use a flat head screw to slowly push it out
Next is to open you lower steering compartment and locate your brake pedal and find the hole similar to this Nissan Primera brake pedal to fit this tiny green brake stopper!
It took me 15mins to finally get the green brake stopper in and now the brake lights is back to normal!
