TOYOTA 47715-43010 Brake Caliper Slide Pin

The genuine Toyota 47715-43010 brake caliper slide pin (PIN, CYLINDER SLIDE) is a critical safety component of the vehicle's braking system. Its function is to ensure the smooth, axial movement of the floating brake caliper during braking, guaranteeing even brake pad contact and wear.

Technical Features and Specifications:

• Material: Premium quality hardened alloy steel for high mechanical strength and wear resistance.
• Surface Treatment: Specialized anti-corrosion coating that minimizes friction and prevents seizing.
• OEM Quality: Genuine OEM Toyota part, ensuring precise dimensional tolerances and an exact fit into the brake caliper bracket.
• Maintenance Requirements: When replacing the slide pin, it is recommended to inspect and replace the rubber dust boots and apply a specialized high-temperature, silicone-based brake grease.

Role of the Caliper Slide Pin and Symptoms of Failure:

In floating caliper brake systems, the slide pins allow the clamping force exerted by the piston to press both brake pads against the brake disc with equal force. If the slide pin seizes or bends, it can cause severe operational issues.

Typical symptoms of failure or wear:

• Uneven brake pad wear: The brake pad on one side wears significantly faster than the other.
• Vehicle pulling during braking: The vehicle pulls to one side when depressing the brake pedal due to uneven braking force.
• Continuous dragging and overheating: The caliper fails to retract completely, causing the brake pad to constantly drag against the disc, resulting in overheating and brake fade.
• Metallic noises: Rattling or squeaking noises from the caliper area due to excessive pin play.
