I know that. You know that. Unfortunately, 99 percent of the driving public don't know that.
Actually, you can brake in a turn... it's called trail braking. Works well for helping the car to rotate in a corner. Doesn't work very well if you have ABS in a FWD car though.
Many Instructors will say "DO NOT TAILBRAKE" or "NO BRAKING IN THE TURN". I agree with the 100% Braking in the turn throws the car completely out of balance. If you are in a RWD car and having problems with understeer in a Turn, you should be using the Throttle to Counter the Understeer. Braking in understeer will just make the Understeer worse.
Now, with a FWD car, there is a technique called "Left Foot Braking" which is VERY difficult to master but a FWD specialist can use left foot braking in a corner to Created more grip in the turn.... its way to fight the understeer.
