FVRITO Hydraulic Disc Brake Kit for Mini Bikes — 50in Left-Hand Hose with Master Cylinder & Caliper for 97cc Baja DB30

FVRITO's 50-inch left hydraulic disc hand brake assembly is a complete upgrade kit — master cylinder, caliper, and hose — designed to replace mechanical brakes on compatible 97cc mini bikes for stronger, smoother stopping power.

This hydraulic brake kit fits specific mini bikes and small-engine off-road machines, including the Baja Doodle Bug DB30 and several Baja Blitz models. It converts a mechanical rear brake into a hydraulic system for improved modulation and reduced lever effort. Read the fit notes and installation details carefully before ordering; this is not a universal direct-swap for all minibikes and some frame modification may be required.

Will this hydraulic brake fit my mini bike model?

Compatibility is limited to certain models and engine sizes. It's built for Baja Doodle Bug DB30 and selected Baja Blitz mini bikes with 97cc, and may work with other 79cc–212cc 2.8HP platforms, but is not a direct replacement for CT100U, Mega Moto 105cc, or some Coleman/Motovox frames without bracket modification.

• Designed for: Baja Doodle Bug DB30, Baja Blitz series (check engine size).
• Not direct fit: Coleman CT100U, Motovox, Mega Moto MMB80/105 unless you modify brackets.
• Hose length: 1270 mm (50 inches) to reach typical rear mounting positions.
• Bottom pump installation pitch: 51 mm (2.01 inches) — verify against your frame.

How does a hydraulic disc brake improve stopping performance?

Hydraulic systems transfer force with fluid pressure, providing more consistent braking feel and stronger stopping power than many mechanical cable setups. The FVRITO kit reduces lever effort while offering smoother modulation on trails, downhill runs, and flat-road braking situations.

• Smoother braking: fluid-actuated caliper movement reduces jerkiness.
• Higher braking force: greater clamping pressure for shorter stopping distances.
• Lower maintenance of lever adjustment compared to cable stretch.
• Sealed hydraulic lines resist contamination and improve reliability.

What must I know about installation and safety?

Proper installation is essential for safe operation. Confirm mounting hole alignment, torque values, and hydraulic connections; incorrect tightening can lead to leaks or failure. If your bike’s original bracket doesn’t match, you may need to cut and relocate the existing bracket or fabricate an adapter.

• Ensure mounting holes match bracket spacing (51 mm pump pitch).
• Bleed the system thoroughly to remove air pockets before use.
• Tighten fittings to manufacturer-recommended torque; avoid over-tightening.
• Test brakes at low speed in a safe area after installation.

What are the kit’s key measurements and parts included?

The assembly comes with a left-hand master cylinder, a compatible caliper, and a 1270 mm (50") hydraulic hose. Those dimensions suit many rear-brake layouts, but always measure your frame routing path and check pump-to-mount spacing before installing.

• Hose length: 1270 mm (50 inches) — room for routing along most frames.
• Pump installation pitch: 51 mm (2.01 inches) for mount alignment.
• Complete kit: master cylinder, caliper, hydraulic hose, basic fittings.
• Intended use: rear brake upgrade on compatible mini bikes and go-karts.

Who is this for: Riders and mechanics who want to upgrade a compatible mini bike’s rear braking performance — especially owners of Baja Doodle Bug DB30 or Baja Blitz bikes — and who are comfortable verifying fitment and performing or arranging a careful hydraulic brake installation. If you need a bolt-on swap for other models like Coleman CT100U or Mega Moto 105cc, plan for bracket modification or consult a fabricator before purchasing.
