service brake

Main vehicle decelerator

The service brake is the main braking system used during normal vehicle operation, as opposed to the parking brake or emergency brake.

It's the brake you engage with the pedal while driving: The service brake felt spongy after the fluid leaked.

The term appears most often in technical, regulatory, or commercial vehicle contexts.
