PACCAR Engine Brake
Overview
The PACCAR Engine Brake is a fully integrated engine compression brake that
provides braking forces through the driveline. It reduces wear on the service brakes
and improves vehicle control in deceleration events when active. The PACCAR
Engine Brake operates using standard dash switches, and is customizable to meet
the requirements of the driver or fleet.
