It replaces the stock mechanical cable brake with a sealed hydraulic caliper, a 180 mm rotor, a dedicated rear caliper bracket, brake pads, and a 50\" hose—engineered for improved modulation and shorter stopping distance on dirt and pavement riding.\u003c\/p\u003e\n\n\u003ch3\u003eWhat exactly is included and how does it fit my minibike?\u003c\/h3\u003e\n\u003cp\u003eThe package contains a hydraulic rear caliper assembly, a rear caliper mounting bracket sized for a 2\" (51 mm) hole spacing, two replacement brake pads, a 180 mm disc rotor, mounting hardware, and a 50\" (approx. 1270 mm) brake hose pre-fitted for standard 7\/8\" (22 mm) handlebars. It is designed as a direct bolt-on replacement for the listed mini bike models so installation is quick and clean.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHydraulic rear caliper and bleeder port for maintenance\u003c\/li\u003e\n  \u003cli\u003e180 mm stainless-style disc rotor for reliable contact surface\u003c\/li\u003e\n  \u003cli\u003eRear caliper bracket with 2\" (51 mm) bolt center spacing\u003c\/li\u003e\n  \u003cli\u003e50\" hose length and handlebar master cylinder sized for 7\/8\" (22 mm)\u003c\/li\u003e\n  \u003cli\u003eMounting bolts, washers, and two brake pads included\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does switching from a cable brake to hydraulic help performance?\u003c\/h3\u003e\n\u003cp\u003eHydraulic brakes transfer lever input through fluid, giving a more consistent, progressive feel and stronger clamping force compared with stretched mechanical cables.

This RZEOZU kit is aimed at minibike owners who ride Monster Moto\/Mega Moto 80cc–105cc or similar Coleman RT\/RB100 models and want crisper, more dependable rear braking. If you run off-road, carry heavier loads, or simply want a modern brake feel in place of an ageing cable system, this kit gives a compact hydraulic solution that installs quickly with the parts included. Note: compatibility is limited to the listed models—confirm fitment and measurements before purchase to ensure proper match.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Will this fit my Mega Moto MM80 or MMB105?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes—this kit is made as a direct replacement for Mega Moto MM80 and MMB105 models listed; confirm the 2\" bracket spacing and 7\/8\" handlebar size before ordering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need special tools to install the kit?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Only basic hand tools and a simple brake-bleeding kit are needed; no welding or frame modification is required for compatible minibikes.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"RZEOZU","offers":[{"title":"Default Title","offer_id":48084228079774,"sku":"B0FPQPS1GP","price":87.48,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/rzeozu-mini-bike-brake-kit-front-assembly.jpg?v=1785848682","url":"https:\/\/northtrailauto.ca\/products\/rzeozu-mini-bike-hydraulic-brake-kit-for-mega-moto-mm80-gmb100-rear-180mm-rotor-50-hose","provider":"North Trail Auto","version":"1.0","type":"link"}
