SFNTXRT Hydraulic Brake Kit for Monster Moto & Coleman RB100/B100 — 50" Hose, 2" Bracket, Sealed Caliper

SFNTXRT Hydraulic Brake Kit converts compatible mini bikes from cable or drum setups to a compact hydraulic disc system for stronger, more consistent stopping performance.

Swap fragile mechanical linkages for a sealed hydraulic caliper and hose that deliver smoother modulation and greater bite when you need it—especially on steep runs, uneven trails, or when riding with extra cargo. The kit ships with the caliper, a rear mounting bracket sized to a 2" (51 mm) hole spacing, two brake pads, mounting hardware, and a 50" brake hose sized for 7/8" (22 mm) handlebars, so it's ready to fit and ride on approved models.

Will this kit fit my Monster Moto or Coleman mini bike?

The SFNTXRT kit is engineered as a direct replacement for specific small-bike models. It targets Monster Moto Mega Moto 80cc/105cc (MMB80/MMB105), GMB100, and Coleman models B100, RB100, and RT100. No frame welding or permanent modifications are required when installed correctly.

• Compatible models: Monster Moto MMB80, MMB105, GMB100; Coleman B100, RB100, RT100.
• Bracket mounting hole distance: 2" (51 mm) for secure caliper fitment.
• Hose length: 50" for routing to 7/8" (22 mm) handlebar master cylinders.
• Check your bike’s existing mount pattern and handlebar master cylinder size before ordering.

How difficult is the installation for a home mechanic?

Installation is intended to be straightforward for anyone comfortable with basic motorcycle or small-engine maintenance. The kit includes the caliper, bracket, pads, hose, and mounting hardware so you can replace the mechanical assembly without specialized fabrication tools.

• No welding or frame cutting required—uses the kit’s bracket and supplied fasteners.
• Requires basic tools: wrenches, hex keys, and possibly a torque wrench for mounting bolts.
• Bleeding the brake line is necessary; a helper or bleed kit makes this faster.
• Estimated install time: 1–2 hours for someone familiar with brake systems.

What performance improvements should I expect?

Switching to hydraulic braking gives a more consistent lever feel and stronger stopping force compared with many stock mechanical setups. Hydraulics reduce lever travel and improve modulation, which helps when you need controlled deceleration on variable surfaces.

• Improved bite and shorter stopping distances under comparable conditions.
• Smoother lever action with less hand fatigue during repeated braking.
• Sealed system resists cable stretch and grime for longer-lasting performance.
• Two replacement pads included for immediate use and spare readiness.

Who is this for? Riders who want a reliable upgrade path from mechanical to hydraulic braking on compatible mini bikes—especially commuters, trail riders, and anyone who frequently encounters hilly or rough terrain. If you own a listed Monster Moto or Coleman model and want stronger, more predictable stopping power without modifying your frame, the SFNTXRT Hydraulic Brake Kit offers a ready-to-install solution. Note: always verify model compatibility and follow safe installation and brake-bleeding procedures before riding.
