1. A system, comprising:
one or more processors coupled with memory to:
determine a value of roughness associated with traversal of a surface by a vehicle;
generate, based on the value of roughness, an instruction to actuate a brake of a wheel of the vehicle to reduce an amount of separation between a rotor of the brake and a pad of the brake;
perform a lookup with the value of roughness to determine an amount of actuation with which to actuate the brake, wherein the amount of actuation reduces the amount of separation between the rotor and the pad to less than a first threshold and greater than a second threshold; and
facilitate, based on the instruction, actuation of the brake of the wheel.
