When rebuilding your caliper with the Moose Offroad 18-3315 kit, cleanliness is paramount. Use a dedicated brake parts cleaner to remove all old oxidation from the caliper bore and piston before installing the new seals. Apply a small amount of clean brake fluid to the new seals during assembly to prevent tearing. Always finish the job by flushing the system with fresh DOT 4 fluid to ensure 100% air-free performance.\u003c\/p\u003e\n\n\u003ctable style=\"width:100%; border-collapse: collapse;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f2f2f2;\"\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eTechnical Specification\u003c\/th\u003e\n      \u003cth style=\"border: 1px solid #dddddd; padding: 8px;\"\u003eDetails\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eMounting Position\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eRear Caliper\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eApplication\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eMoose Racing \/ OEM Replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eKit Contents\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eRubber Seals, Boots, and Brake Pins\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eFitment Range\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #dddddd; padding: 8px; text-align: center;\"\u003eBeta 125cc - 525cc (2005-2024)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFAQ Questions\u003c\/h3\u003e\n\u003cp\u003eQ) \u003cb\u003eDoes this kit include the caliper piston?\u003c\/b\u003e\u003cbr\u003e\nA) No, this is a seal and hardware kit.
