I take it you do not actually ride anywhere with your bike. The first thing one learns with a road bike is to not depend on the front brake or it will send the rider over the handlebars. It is why the rear brake lever is on the right side as that is the stronger and dominant hand for most people. With mountain bikes it is a different situation with trail riding but that is a special case. Track bike have no front brake and no rear brake and this has always been the case. Maybe it is time to expand your limited knowledge.

My first serious bike had tubular tires or "sewups" and these are glued onto the rims. With too much heating of the rim from the rim brakes the glue softens and the tire can be dislodged from the rim. On on long downhill grade I found myself having to make a rapid stop with a car in the wrong lane and I peeled the front tire completely off the rim. More than a little unsettling and I was happy to have not crashed the bike and only did some damage to the rim.
