The kit includes a rear caliper, bracket sized to fit the factory frame mounting points, brake pads, mounting hardware, and a pre-measured hose so you can install without cutting or welding. It’s a direct replacement designed to match the MMB80, MMB105 and RB100 rear mount geometry—always check dimensions before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eWill this hydraulic kit fit my Mega Moto MMB80 or MMB105 rear brake?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the bracket and caliper are tailored to the listed minibike models and sit in the same 2\" (51 mm) hole spacing used on those frames.
