After undertaking an intermediate riding course on my 06 Triumph America, I decided I needed to practice my emergency stopping technique. So I found a nice quiet stretch of bitumen and stopped quickly several times. Until the last time, I ran out of brakes. The brake level had no more brake left in it and when I looked at the front caliper is was dripping brake fluid. Obviously, I had braked very hard several times and had overheated the fluid, but is this normal?
