Feralmoto Mini Bike Hydraulic Brake Caliper Bracket Kit — Coleman B100/RB100 Fit, bolt-on conversion with master cylinder

Feralmoto's Mini Bike Hydraulic Brake Caliper Bracket Kit is a complete bolt-on conversion set that replaces cable rear brakes with a small-caliper hydraulic system for compatible 80–105cc mini bikes.

This all-in-one kit is built to bring smoother, more consistent braking to Coleman B100/RB100, FRP GMB100, Monster Mega Moto MM-B80/MM-B105, and Realtree RT100 mini bikes without welding or frame modification. The package includes a laser-cut steel bracket, a compact hydraulic master cylinder, a pre-filled hose, a compatible control lever, and mounting hardware so you can swap from cable to hydraulic braking quickly and with few tools.

How does this kit improve braking compared to cable systems?

The hydraulic setup delivers firmer, more even stopping power and better modulation under load, especially on rough terrain or steep descents. Because fluid transmits force more efficiently than a stretched cable, you’ll notice quicker engagement and less lever travel.

• Smoother force transfer for predictable braking response
• Improved modulation — easier to control bite and release
• Reduced maintenance versus stretched or frayed cables
• Better rear-wheel stability when braking hard

What is included and will I need extra parts?

The kit is intentionally complete so you don’t have to source separate components. It was designed to match small 51mm hydraulic calipers and includes all necessary fasteners for direct mounting to compatible frames.

• Laser-cut steel caliper bracket with protective coating
• Compact hydraulic master cylinder with lever
• Pre-filled hydraulic hose and fittings
• Mounting bolts and installation hardware

How difficult is installation and what tools are required?

Installation is a bolt-on process that doesn’t require frame modification for the listed models. Typical hand tools are sufficient, and the pre-filled hose cuts out the need to bench-bleed the system for most installations.

• Standard socket set or metric wrenches for mounting bolts
• Hex keys for lever and bracket adjustments
• Torque wrench recommended to secure fasteners properly
• Minor trimming or repositioning of cable anchors may be needed in some installations

What materials and design choices make this kit durable?

The bracket is precision-cut from thick steel and finished with a black protective coating to resist corrosion from outdoor use. The cutout pattern reduces weight while retaining rigidity so the bracket supports braking forces without flex.

• Laser-cut steel for consistent fit and strength
• Corrosion-resistant black coating for outdoor longevity
• Optimized cutouts to balance weight and stiffness
• Pre-assembled hydraulic line minimizes leak points during install

Who this is for: Riders who own compatible 80–105cc mini bikes and want a practical, factory-like upgrade from cable rear brakes to a hydraulic system will benefit from this kit. It’s aimed at DIY mechanics, weekend trail riders, and anyone seeking improved braking performance and reliability without extensive frame modification. If your mini bike model is listed (Coleman B100/RB100, FRP GMB100, Mega Moto MM-B80/MM-B105, Realtree RT100) and you want quicker, more controllable stopping power, this Feralmoto kit provides a compact, ready-to-fit solution.
