I almost always over break to the point where I am getting back on the gas to get to the corner as I slowed down too much, which I guess is better than under breaking and ending up in the grass
I liked the idea someone had about putting cones out there to mark break points, I can flow lines from you guys all day long but since you have no break lights I cant learn your exact breaking techniques at all.
Turn 1 at Putnam is a prime example one of these turns for me, coming over that hill I am always positive I'm too hot, mid corner I'm kicking myself as I know I could have gone much much faster.
Braking too early is better than braking too late.
One of the key benefits to the race track is that we get to repeat, repeat, and then repeat. SO... that means that should you brake too early, wait a little longer to brake each successive lap until you reach your comfort point.
The cones, or some other external reference point is an excellent place to start. Try to brake in exactly the same manner every lap, same pressure, length of braking zone, etc.. in order to establish some baseline consistency. Then as mentioned above, brake later and later after your chosen braking point until it begins to get a little uncomfortable. It is KEY that you do this a little at a time, we aren't trying to get you to crash or miss the corner. One of the big things to think about is repetition. SMALL changes, baby steps, from a place where you can measure each change from will make it easy to brake later and pick up the throttle earlier. Concentrate on knowing your markers, make yourself mental notes for each and every marker. (Example: Ask any CR or A rider on where to turn in at T6 at Autobahn North, and they will all tell you about the corner of the patch)
As far as using a cone for the point to start braking, that just won't work. Cones are excellent to mark turn in points, apexes, and exits. Those are fairly consistent target points, however braking is a factor of how good your brakes are, how good your pads are, how well bled your master is, how fast you are going, how good your tires are, how much you weigh, available traction, and of course, the two biggest factors, how fast you are going, and how fast you can take the corner. ALL of these are individual points, which of course vary from rider to rider.
T1 at Putnam is a great example. How fast is it? Where does one brake? Some folks are still full throttle coming over the hill towards T1, some are off the throttle way earlier than that. Some brake hard entering T1, while others bang down a gear or two and rail through T1. A 250 needs zero brakes there, a liter bike might need brakes, depends on the rider.
The biggest thing that I can tell you is to reiterate what Dr. Skloss said above, practice, practice, practice. Time on the track will acclimate you to speed. The speeds that I went at the end of last season made me feel like I was gonna crash any second, and that my hair was on fire. Now, those speeds seem beyond tame to me. I can ride far above my prior speeds basically turned around watching the rider behind me navigate the turn, while I am completely relaxed. That comes from track time. Practice, practice, practice.
Wanna slow the track down? Look farther ahead.
It is amazing how our minds become more and more accustomed to the speed as we continue to go faster and faster.
