I took driver's ed waaaay back in 1968 and was taught that pumping your brakes when slowing is a good technique for two main reasons. First is that the brakes going on/off gets the attention of the driver in the rear and secondly, between pumps allows brake cooling. Made sense to me and I use the technique today. Being a biker, I am acutely aware of drivers behind me and want to alert them when I intend to slow so by pumping a brake lever in a random order, I get their attention. I have adjusted both levers to activate the brake light at the point where slack is met with actually braking so that I can use the technique effectively while still getting the maximum longevity of my pads. What do other riders do in this regard?
