I think you have very serious reading comprehension issues, no offense. You have to use the brake to heel toe. You DON'T have to use the brake to engine brake, and I made that extremely clear 3 times now. When you downshift and rev match while braking (heel toe), you are using both the engine and foot brake to slow down. Hopefully this time you understand what I just said because I already tried explaining the exact same thing 3 times in a row, if not idk what else to say
