3556032 Caliper Tappet and Dust Boot Kit

What does a brake caliper tappet do?

This brake caliper tappet and dust boot plays a critical role in the movement of the air disc brake caliper assembly. By facilitating smooth sliding and protecting internal components, it helps maintain consistent braking force and prevents premature wear of the braking mechanism.

Fitment and technical specifications

This specific component is designed for heavy commercial vehicle applications where durability is paramount. The kit features a Ø 74 mm diameter to ensure precise fitment within the caliper assembly, providing high-strength protection against road debris and moisture.

Installation and maintenance

During installation, technicians should carefully inspect the caliper mounting pins to ensure they are clean and properly lubricated before fitting the new tappet and boot. Maintaining these components according to service intervals prevents uneven pad wear and ensures optimal braking responsiveness.

Component inspection

Regular inspection of the dust boot is recommended to detect any signs of tearing or degradation that could allow grit into the caliper mechanism.
