Feralmoto Hydraulic Brake Kit for Mini Bikes & Small ATVs — Bolt-On Steel Bracket, Prefilled Master Cylinder

Feralmoto's bolt‑on hydraulic brake kit converts compatible mini bikes and small ATVs from cable brakes to a full hydraulic rear braking system for stronger, more consistent stopping power.

This all‑in‑one conversion package brings a prefilled master cylinder, reinforced mounting bracket, hydraulic hose and lever, and hardware to upgrade FRP GMB100 98cc, Motovox MBX10, Monster Mega Moto MM80/105cc platforms, and several Coleman CT100U/CC100X models (not for Coleman B100). The kit is engineered to accept standard 63mm ATV‑spec calipers, replacing undersized mini calipers to improve brake modulation and durability without welding or permanent frame changes.

How does the Feralmoto kit improve braking compared with a cable system?

Hydraulic systems transmit force more efficiently and resist cable stretch, offering faster, more consistent engagement and better lever feel. That translates to improved modulation when slowing from speed or navigating uneven terrain.

• Hydraulic master cylinder prefilled for immediate operation
• Reduces lever travel and increases clamping force vs. cable drums
• Better heat and load tolerance under repeated stops
• Improved rear wheel stability and pedal/lever feedback

Will this bracket and caliper spacing fit my bike or ATV?

The bracket is laser‑cut to accept 63mm ATV‑spec caliper mounts commonly used on small ATVs, providing a precision fit for upgraded calipers. Measurements should be verified against your machine’s rear hub and rotor before purchase.

• Designed for 63mm mount spacing (ATV standard)
• Includes spacers and washers to fine‑tune alignment
• Bolt‑on design avoids frame modification or welding
• Compatible with FRP GMB100, MM80/105, and listed Coleman models

What’s included and how difficult is installation?

The kit contains the bracket adapter, a hydraulic master cylinder with lever, a prefilled hose, and all mounting bolts, fittings, spacers, and washers. Installation is intended to be straightforward for anyone comfortable with basic hand tools and mechanical adjustment; bleeding or prefilled hoses reduce setup time.

• Complete hardware pack: bolts, spacers, and fittings included
• Prefilled hose minimizes bleeding steps
• No welding—bolt‑on swap with common wrenches and sockets
• Powder‑coated steel bracket resists corrosion and wear

How does the bracket hold up under heavy use and maintenance needs?

The mounting bracket is made from thick, laser‑cut steel and powder coated for long life, keeping caliper alignment stable under load. Routine checks of fastener torque and brake fluid level are all that’s typically required to maintain reliable performance.

• Heavy‑duty steel construction for dimensional stability
• Powder coating prevents rust and surface wear
• Easy access to bleed nipple and hose routing for service
• Replacement hardware readily available for periodic maintenance

Who is this for? The Feralmoto Hydraulic Brake Kit suits hobbyists, restoration builders, and riders who want a tangible safety and performance upgrade for small bikes and youth ATVs that originally shipped with cable or undersized caliper brakes. If you own one of the compatible models and want a bolt‑on conversion to a 63mm ATV‑spec hydraulic setup with minimal fabrication, this kit delivers a practical, durable solution.
