I have a 1992 Toyota Pickup truck. I use the brake lever all the time when i park. Recently when I leave my parking spot I will push the lever back in and then after a few seconds it will pop out an inch or two and the brake light will come on. Basically there is a springiness to it and it won't leave it in its off position. Do you know if I need to tighten something or what I should do to fix this? Thanks!
