Genuine 44139-ZK30A Brake Caliper Guide Pin

The Genuine 44139-ZK30A is a factory OEM disc brake caliper guide pin designed for select Nissan vehicles from 2005 to 2017. This precision-engineered component ensures proper floating caliper operation by allowing the brake caliper to slide smoothly and evenly during braking, which is essential for balanced pad wear and optimal stopping performance.

Key Features:

• Factory OEM Nissan part manufactured to strict quality control specifications
• Allows caliper to float and slide for even brake pad application on both sides of the rotor
• Prevents uneven pad wear, brake drag, and caliper seizure when properly maintained
• Front lower position application (through 03/2016 production)
• Direct replacement for worn or seized guide pins
• Backed by Nissan manufacturer warranty

Guide pins are critical components in floating caliper brake systems. They enable the caliper to slide back and forth when hydraulic pressure is applied, ensuring both the inner and outer brake pads clamp evenly against the rotor. When guide pins become corroded, seized, or improperly lubricated, the result can be premature pad wear, reduced braking efficiency, pulling during braking, and potential safety issues. Regular inspection and proper lubrication with high-temperature brake grease during brake service is essential for maintaining smooth guide pin operation and extending brake system life.
