Product Description:

RCK69103 – Adjusting Mechanism Nut Set is a set of precision threaded and nut components that plays a central role in the automatic clearance adjustment system of heavy-duty disc brake calipers. This mechanism supports stable braking system response by regulating the working distance between the brake pad and the disc in a controlled manner. Thanks to the gear tolerances in its internal structure, it contributes to the stability of the adjustment unit.

The condition of this set directly affects braking characteristics during caliper overhaul and maintenance. Worn or deformed adjustment nuts can cause irregular clearance control. This can lead to changes in brake pedal feel, uneven brake pad contact, or undesirable system friction. Replacing the RCK69103 helps to reassure the precise and balanced operation of the adjustment mechanism.
