FVRITO left hydraulic brake master cylinder and caliper assembly is a direct-replacement braking unit designed to upgrade or repair 50cc–125cc Chinese ATVs, quads and mini bikes.

This left-side hydraulic brake kit includes the master cylinder with lever perch, hose, caliper, an extra set of brake pads, a brake switch and mounting hardware so you can restore consistent stopping power on a wide range of small-engine off-road machines. It’s engineered to fit many popular Chinese models (Taotao, Coolster, Roketa, Vitacci, ICEbear, Baja, Kazuma and others), and the listing provides key measurements to confirm compatibility before purchase.

Will this brake assembly fit my 50–125cc quad or mini bike?

Compatibility depends on mounting spacing and lever perch diameter more than the brand name alone. Use the listed dimensions to cross-check your machine: the lever perch is 22 mm and the caliper mounting hole center-to-center is 63 mm. If those match, the supplied 1500 mm brake hose gives flexibility for most frame layouts.

• Brake lever perch diameter: 22 mm (0.87 in)
• Caliper mounting hole distance: 63 mm (2.48 in)
• Brake hose length: 1500 mm (59.06 in)
• Compatible brands: Taotao, Coolster, Roketa, Vitacci, ICEbear, Baja, Kazuma and many Chinese makes

What comes in the package and what tools or parts might I still need?

The kit arrives with the assembled brake unit plus several useful extras so you can install or service the system right away. You’ll receive the brake assembly, three cable ties, an extra pair of brake pads, a fuel filter and an extra brake switch; basic hand tools are typically all that’s required for installation.

• Included: 1 brake assembly, 3 tie straps, 1 extra brake pads set

How does the assembly perform and what should I expect after installation?

Once installed and bled properly, the hydraulic caliper and master cylinder provide predictable lever feel and stronger, smoother stopping than many worn mechanical systems. This assembly is designed for small-displacement off-road vehicles, offering reliable service for daily riding and recreational use when maintained correctly.

• Delivers hydraulic braking for improved modulation over worn cables
• Includes spare pads to extend service intervals
• Durable cast caliper and sealed master cylinder for off-road conditions
• Requires proper bleeding for optimal lever feel

Who is this for? If you own a 50cc–125cc Chinese-brand ATV, quad, or mini bike and you need a left-side hydraulic brake replacement or upgrade, this FVRITO assembly is aimed at you. It’s suitable for hobbyists, DIY mechanics and repair shops that want a cost-effective, bolt-on solution compatible with many models. Before ordering, verify the 22 mm perch, 63 mm caliper mount spacing and hose routing will work with your machine; contact the seller with photos or model details if you’re unsure.
