It includes a preassembled caliper, master cylinder sized for left 7\/8\" handlebars, a 50-inch brake hose, brake pads and basic mounting hardware so you can replace or refresh the rear brake setup quickly.\n\n\u003ch3\u003eWill this fit my Baja Doodle Bug DB30 or Blitz mini bike?\u003c\/h3\u003e\n\u003cp\u003eYes — the kit is made to fit Baja Doodle Bug DB30 (including Baja Blitz, Baja Racer, Baja Dirt Bug) and other 97cc–98cc, ~2.8–3.0hp mini bikes that share the same mounting pattern. Confirm your bike uses left-side 7\/8\" handlebars and has a 2\" center-to-center caliper mount spacing before ordering.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for Baja DB30 and similar 97cc–98cc mini bikes\u003c\/li\u003e\n  \u003cli\u003eLeft-hand 7\/8\" handlebar master cylinder configuration\u003c\/li\u003e\n  \u003cli\u003eCaliper mount: 2\" center-to-center bolt spacing\u003c\/li\u003e\n  \u003cli\u003eSome models may need minor brake-mount modifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does it improve braking performance on trail or street rides?\u003c\/h3\u003e\n\u003cp\u003eThe hydraulic caliper offers firmer, more immediate clamping than typical mechanical systems, producing steadier stopping force under load and repeated braking.
