Nothing to do with the OP's post.
I remember using my front brake mostly when I was younger over 40 years ago, because the rear cable was seizing due to lack of use
This all changed over night when I grabbed the front brake and due to lack of maintenance at the time (as I used to leave bike outside and didn't add lube till something squeaked
) the front nipple dropped out of the lever
On the bonnet and walking home
As most of my riding is down lanes - off road - moorland track etc, the back brake comes on first but is then joined by the front brake and I pull back with somewhat equal pull.
The result is that if its slippy then the back starts to slip and you can still control the steering, bear in mind that most of my riding is with a loaded bike of about 50 Ibs, and at times I will be just locking the rear and applying a small amount to the front to get max braking with no loss of control.
Motorcycles have whopping twin disc and a some what mediocre rear drum, and cars where like this for years, disc up front and drum at rear.
Riding on slippery surface with all two wheeled vehicles means you use the front as little as possible, your odds of reacting to a front wheel slide on corners is not good, rear on the other hand is relatively easy to master.
In the dry on a road bike you can afford to use the front quite hard as grip is not a problem with the weight moving to the front as you de-accelerate, the rear will lock easily because as with cars some 70% of braking is via the front.
Today I would probably never just apply one brake unless I was scooting then it would be the rear, applying the front scooting full weight on one side of bike won't fell good and easy off as it affects steering.
Riding motorcycles in all weathers you learn how to feather brakes especially with ice snow etc, probably easier on a motorcycle than a bicycle as the engine is a very controllable drag brake, acting on the rear.
Consequently my rear rim is always the first to suffer brake wear, I think this is where discs come into there own as loaded off road riding is chronic on rim brakes, fair weather road bikes can keep rim brakes.
P.S. Open Pro rims, never seen one and am still using early eighties rims / touring types, they seem to have equal likes and dislikes from the posts so I am not probably missing much, Argents have nearly two mm's of wall.
