4108002 Adjustment Bolt, Brake Caliper Tappet

The 4108002 adjustment bolt is a critical component within the air disc brake caliper mechanism, specifically serving as a brake caliper tappet. This part is engineered to ensure precise movement and stability within the braking system, providing reliable functionality under heavy-duty braking-suspension loads. Its robust construction is designed to withstand the constant mechanical stresses found in heavy commercial vehicle braking environments.

4108002 is the OE-equivalent adjustment bolt used in MERITOR DX 195 and DX 225 systems. This component is also compatible with various heavy commercial vehicle applications involving brands such as DAF, VOLVO, CATERPILLAR, and BREDAMENARINIBUS. Maintaining the integrity of the caliper tappet is essential for ensuring the consistent performance of the entire air disc brake assembly during operation.

Workshop technicians should ensure that the direction (R) is correctly verified during installation to maintain proper assembly alignment. Regular inspections of the brake caliper tappet and adjustment bolts are recommended during standard service intervals to prevent wear-related issues. This part is designed for seamless integration with compatible MERITOR hardware to maintain optimal braking responsiveness and safety in professional fleet maintenance.
