Product Description
This genuine Nissan brake caliper guide pin (part number: 44140-EJ20A, alternative OEM number: 44140VB201) is a premium quality, precision-engineered component that ensures the smooth and safe operation of floating caliper disc brake systems. The guide pin (also known as a brake caliper slider) allows the brake caliper to move accurately and evenly toward the brake disc during braking, ensuring optimal contact and alignment of the brake pads.
Technical Features and Specifications:
- Part Type: Brake Caliper Guide Pin / Slide Pin
- Manufacturer: Nissan (Genuine OEM part)
- OEM Part Number: 44140-EJ20A
- Alternative / Supersession Part Number: 44140VB201
- Material Composition: High-tensile, heat-treated steel alloy designed to withstand high mechanical stress and resist corrosion.
- Surface Finish: Equipped with an anti-friction and anti-corrosion coating for smooth sliding action.
Role and Importance of the Brake Caliper Guide Pin:
In floating caliper braking systems, the caliper must be able to move axially. The guide pins provide this sliding movement. If the guide pins become damaged, bent, or seized due to lack of lubrication, the brake caliper cannot retract properly. This can lead to continuous brake pad dragging, excessive heat build-up, and a severe reduction in braking efficiency.
Typical Symptoms of Wear or Failure:
- Uneven brake pad wear between the inner and outer pads.
- Unusual squeaking or metallic grinding noises originating from the brake assembly.
- The vehicle pulling to one side while braking.
- An unusually soft or excessively stiff brake pedal feel.
- A seized or sticking brake caliper, leading to severe overheating of the wheel rim and braking system components.
During routine brake system maintenance, inspecting, cleaning, and lubricating the guide pins with a dedicated high-temperature silicone-based brake grease—or replacing them immediately if worn or damaged—is strongly recommended to maintain maximum road safety.
