NISSAN D1ABM-VB225 Brake Caliper Repair Kit

The NISSAN (SKU: D1ABM-VB225) brake caliper repair kit is a premium quality seal kit manufactured to factory specifications, designed to maintain the safe and efficient operation of the braking system. The original OEM reference (OEM: 41120VB225) guarantees a precise fit and dependable sealing during brake caliper overhaul.

Technical Features and Kit Contents

The brake caliper repair kit is engineered for comprehensive sealing and protection of the brake caliper piston and guide pins. The kit typically contains the following components:

• Piston Seals: Made from specialized brake fluid-resistant EPDM rubber material, ensuring the retention of hydraulic pressure and preventing brake fluid leakage.
• Dust Boots: Protect the caliper piston and guide pins against dust, moisture, road salt, and other contaminants, preventing corrosion and piston seizure.
• Bleeder Screw Caps: Prevent dirt and debris ingress through the bleeder valve.

Function and Importance of Brake Caliper Seals

The rubber seals within the brake caliper are continually exposed to high temperatures, mechanical stress, and environmental elements. Over time, rubber loses elasticity, hardens, or develops cracks. Damaged seals can result in brake fluid leaks—drastically diminishing braking performance—or lead to piston corrosion and sticking due to moisture intrusion.

Typical Symptoms of Wear or Failure

• Visible brake fluid leaks around the brake caliper or on the inner rim of the wheel.
• An unusually soft, "spongy" feeling brake pedal during deceleration.
• Sticking or seized caliper, leading to brake overheating, continuous drag, and premature brake pad wear.
• The vehicle pulls to one side during braking due to uneven braking force.
