When I first started biking inn the late 70's I was taught to ride by my older brother and that was just the basics. This is how you pull out, this is how you turn et'c, et'c,.
I was 16 and graduating from pedal power to engine power and, trust me on this, if you used the front brakes to stop the bike like you do on a motor bike You where OFF, no question.
I have talked with many of my contemporaries and they all did the same thing. Many of them still being rear brake heavy up until such times as they tried instructed track days or advanced training. I was broken of the habit when I had to re-take my licence about 15 years ago.
That being said there are always occasions when using more rear than front is sometimes a better way of slowing. Very slippery conditions, I'd rather have the back squirm as it locks than let the front wash out.
Like others I would suggest practicing stopping on some empty straight roads. Here in the UK part of the Driving test for Motorcycles is an emergency stop so you are taught basic techniques of front first and then rear as you come to a stop. works well but how many of us actually practice emergency braking or even hard braking unless the situation arises when it is definitely needed. NOW.
I'd suggest trying a few now and then. keeps you in touch with how the bike feels under hared braking
