4104021 Compatible Brake Caliper Tappet Bolt

What does a brake caliper tappet bolt do?

This brake caliper tappet bolt plays a critical role in the air disc brake system by maintaining the correct positioning and adjustment of the caliper components. Manufactured with high-strength components, it is designed to withstand the intense mechanical stresses and thermal fluctuations encountered during heavy-duty braking cycles.

System compatibility and application

This component is utilized in various heavy commercial vehicle braking systems to ensure smooth caliper movement and consistent pedal feel. By providing a stable mounting point for the tappets, it prevents uneven pad wear and maintains system integrity during operation.

Installation and maintenance guidance

The bolt is specified with an M10 x 1.5 thread and a 20 mm dimension to ensure precise fitment within the caliper assembly. Technicians should verify that all mounting surfaces are clean and that torque specifications are strictly followed during installation to prevent loosening under vibration.

Troubleshooting and inspection

Regular inspection of the caliper tappet assembly can help identify early signs of wear or loosening. Ensuring that the adjustment bolt is properly seated helps maintain the optimal service life of the entire pneumatic braking system.
