Maintain a clean and properly sealed braking system with this Genuine Nissan Brake Master Cylinder Reservoir Cap, designed to suit Nissan Patrol GU Y61 models. This OEM cap fits securely on the brake fluid reservoir, helping protect the brake system from dirt, dust, moisture, and other contaminants that can affect brake fluid quality and overall braking performance.

Over time, the original reservoir cap can become brittle due to constant heat exposure, engine bay vibration, brake fluid fumes, and age. In many cases, the sealing rubber can perish, locking tabs may break, or the cap may go missing during servicing. A damaged or missing cap can allow contamination into the brake fluid, which may lead to reduced braking efficiency, internal corrosion, and unsafe braking performance. Replacing it with a Genuine Nissan cap ensures a secure factory seal and helps maintain reliable brake system operation.
