This is my 1st venture into a forum. l came here hoping someone here might save my life. I quit riding in 82 when I became a dad. Fast forward to 2018 when i bought the 2017 Kawasaki x 300 versus intending to stay off the roads of texting drivers. A month later after a safety course I am back to my old vintage 1982 self, riding aggressively enough to stay ahead of traffic putting myself in the sweet spot. I now have 3 additional bikes. A 98 Honda Valkyrie Tourer, which led to 99 Honda Valkyrie Interstate (wanted the CB/FM radio full dresser look) and an 03 Honda VTX 1300 I got really great deal on. The Interstate is my baby and has taken me to Tennessee and back twice. I am having issues with the rear brakes on the Interstate just disappearing from time to time. Pedal goes down and bam, no rear brakes. Topped off fluid, tried putting weight on it overnight and thought it was fixed. Coming home today, lost rear brakes again. Got home, shut off bike. Went back in 10 minutes and had brake pedal pressure. Any one with ideas of what could cause this. I'm here to learn more about how motorcycles work and to become a better rider. In addition, does any know the location of the CB fuse. I can't find it and the CB has never powered on. I might not know what to do to power it up.
