CILOYU Mini Bike Brake Lever Kit — 180mm Rear Disc Upgrade for CT100U, 7/8in Lever & Caliper

The CILOYU Mini Bike Brake Lever Kit is a complete rear-disc upgrade that replaces worn drum setups and delivers firmer, more predictable stopping power for CT100U and similar mini bikes.

If you ride a Coleman CT100U, CC100X, Baja Motorsports or many popular mini bikes, this CILOYU kit provides the parts to convert or refresh the rear brake system with a 180 mm steel rotor, rear caliper, lever and cable. It’s built for direct bolt-on compatibility with 7/8" (22 mm) handlebars and includes pads, mounting hardware and a pre-measured cable so installation is straightforward for home mechanics and garage tinkerers.

How does this kit improve braking compared with stock components?

The kit replaces weaker or worn stock parts with a steel 180 mm rotor and a rear brake caliper designed for better bite and modulation. The lever’s smooth pull and the abrasion-resistant cable help transmit force efficiently, giving you a shorter, more controlled stopping action.

• 180 mm stainless steel rotor resists warping and preserves braking surface.
• Smooth-action 7/8" brake lever for predictable modulation.
• Abrasion-resistant cable for consistent response under load.
• Two brake pads included for immediate installation.

Which mini bikes and handlebars will this kit fit?

This CILOYU assembly is compatible with a broad range of small off-road bikes and pit bikes, including Coleman Powersports CT100U, CC100X, selected Baja and Monster Moto models. The lever mounts on standard 7/8" (22 mm) handlebars and the caliper’s 51 mm mounting-hole spacing matches many mini bike frames.

• Designed for 7/8" (22 mm) handlebars — common on mini bikes.
• Compatibility list includes Coleman CT100U, CC100X, Baja, Doodlebug DB30, Motovox MBX10/MBX11.
• Rear caliper configuration — check front/rear differences before ordering.
• Mounting hole distance 51 mm, rotor diameter 180 mm for standard fitment.

What are the kit dimensions and included parts?

The package contains the lever, a 61" cable assembly, rear caliper, two pads and a 180 mm rotor; key measurements are provided so you can confirm fit before installation. Cable sleeve and stroke specs are included to help ensure correct routing and lever travel on your bike.

• Brake lever for 7/8" (22 mm) bars; cable overall length: 61" (155 cm).
• Cable sleeve length: 55" with moving length ~4.96" for proper adjustment range.
• Rotor: 7.08" (180 mm) diameter with 37 mm center hole diameter.
• Caliper mounting hole distance: 51 mm; kit ships with pads and hardware.

How easy is installation and what should I check first?

Installation is achievable with basic hand tools and a bit of mechanical familiarity. Before you begin, confirm you need a rear caliper (this kit is rear-specific), check mounting hole spacing, and verify the handlebar diameter to avoid fitment problems.

• Check that your bike uses a rear caliper mount and 51 mm hole spacing.
• Ensure handlebars are 7/8" (22 mm) to accept the included lever.
• Basic tools: wrenches, Allen keys, and a torque wrench for safe tightening.
• Adjust pad clearance and cable tension after fitting for proper bite.

Who is this for: Riders and DIY mechanics who want a reliable rear disc brake replacement or upgrade for small off-road and pit bikes. It’s ideal for owners of CT100U, CC100X and similar models who need a durable steel rotor, a responsive lever, and an abrasion-resistant cable in a single, ready-to-install package. Avoid if you require a front caliper or a different rotor size — verify fitment before purchase.
