A drum-in-hat parking brake design is intended to hold a stopped vehicle rather than slow down a moving one.

A drum-in-hat parking brake is built to hold the vehicle in place when it’s stopped. It uses a cable to apply shoes against a small drum integrated into the rotor hat, creating friction that locks the wheel so the car won’t roll on inclines or after you’ve parked. This design is meant for static holding, not for slowing down a moving car, so relying on it for speed reduction can cause uneven braking, excessive heat, and loss of control. The main braking from speed is handled by the service brakes, which are designed for dynamic braking and heat dissipation. Some systems may interact with ABS, but the parking brake’s primary purpose remains to secure the vehicle when stationary, not to assist or replace high-speed braking or steering during braking.
