You know what's freaky is I am always practicing panic stops out on the lonely country roads but NEVER IN THE WET!! This is incredibly stupid because that's when you need the technique the most!
The gentle approach really does work in the wet as I don't usually have a problem but the panic stuff made me throw all that 'finesse' stuff right out the window (or off the seat??)
I'm just surprised I grabbed the rear brake right away...I have a ton of gravel on the pavement rightat the end of my drive and have to stop on that every day. If I use the front, I'll go down for sure, so I always use the rear. Maybe that got me into a bad habit??
Well, the wet scares the best rider until they learn to deal with it. It does provide a different set of rules. Or at least a modified set. Now that you now, I'm guessing you'll be practicing.
Same as I do. Since as much as I'd like to be one of the best,... I have a LONG way to go. I might make it by the time I turn 90,... if I practice every day.
The good part about all of this is that now you know what you're programmed response is, and that you have to re-program. And you did it with no permanant damage.
Why do you say if you use your front brake on gravel you'll go down for sure? I use my front brake for all of my stops, and rear to bring the bike to a faster stop, or to stabilize the bike. (Often I use the rear with the front out of habit) In the dirt, I use almost exclusively the front brake. one notable exception is to "slow myself" down when going down a steep sand dune that I have to make a sharp left at the bottom of, or else free fall for another 100ft. Then there's a lot of rear brake and a little front.
It's all about moderation.
