Hi all, Was practicing my slow speed riding today (mostly figure 8's) to practice for my P's test, using throttle and rear brake to control the speed. After around 10-15 mins of constant figure 8's, the rear brakes became spongy then I had no rear brakes anymore. So then I rode home (with no rear brakes). Took me 5 mins to get home, parked the bike in the garage, turned off the engine and now my rear brakes work again?? WTF? Did I momentarily lose the rear brakes due to excessive use and it overheating? If so, then how can I practice my slow speed maneuvering if I can't use my rear brakes constantly? Am I doing something wrong? I'm confused.
