1. A computer-implemented method, comprising:
determining activation parameters for an autonomous driving vehicle (ADV), wherein the activation parameters include historical usages of a primary brake system or a secondary brake system;
in response to determining that a brake is to be applied, determining whether to activate a primary or a secondary brake system based on the activation parameters;
sending an activation flag to activate the primary or the secondary brake system based on the determining whether to activate the primary or the secondary brake system; and
sending a brake command to the primary and the secondary brake system to activate either the primary or the secondary brake system according to the activation flag.
