Product Description:

The RCK03103 Adjuster Pinion Gear is a precision brake caliper repair component located at the heart of the automatic adjustment group in heavy-duty disc brake systems, providing motion transmission. By transmitting rotational force in a controlled manner within the caliper mechanism, it increases system precision during brake caliper repair and reconditioning processes.

Used in service and maintenance applications, this part ensures the balanced and synchronized operation of the adjustment mechanism during brake caliper overhaul and caliper brake repair; it reduces gear wear, adjustment errors, and performance losses, offering a more stable, safe, and long-lasting braking performance.
