no they don't have wear sensors on them, but if you look at your pad they have two or three grooves cut into them....these are like wear bars on tires except in reverse.....when the grooves are no longer there its time for new pads...

 

EBC HH pads are great! I just replaces the OEM pads, and after 13k miles on my 07 1kRR they still looked new but felt a little off. When I put the EBC HH pads on I also replaced the lines with Galfer steel braided lines and a good synthetic DOT4 brake fluid.
Don't grab too hard anymore or she'll flip over on ya'!
