The Acura Legend utilizes a four-wheel disc brake system, a standard feature since its inception, and includes an Anti-lock Braking System (ABS). The ABS, designed by Acura, helps prevent wheel lockup during braking, maintaining stability and control. The ALB system on the Legend features two hydraulic circuits and an electronic control circuit, with a fail-safe design where the primary hydraulic system provides braking if the ALB circuit fails.
