It is extremely atypical to be braking at 0.5g. That is an emergency braking situation, in which case, it is perfectly reasonable to be engaging the mechanical braking.

Modern cars emergency brake at 0.87-1.08g. Maybe 0.5g is not your everyday braking, but not something you'd remember in a few weeks. https://www.sae.org/publications/technical-papers/content/20...
