What does a brake caliper tappet do?

This brake caliper tappet and dust boot assembly plays a critical role in the air disc brake system by maintaining the correct alignment of the caliper components. By providing a sealed environment, it protects sensitive parts from contaminants, ensuring smooth and reliable braking performance under heavy-duty conditions.
