RZEOZU Mini Bike Brake Lever Kit Replacement for Coleman

RZEOZU Mini Bike Rear Disc Brake Kit is a complete 7/8" handlebar lever, 61" cable and rear disc caliper set designed to restore reliable stopping power on Coleman CT100U and many 79–100cc minibikes.

This replacement brake kit supplies the essential components to upgrade or repair the rear braking system on a range of small-engine minibikes. Built from hardy steel parts and supplied with pads, fasteners and simple hand tools, the kit arrives ready for installation and tuned for mechanical durability and repeatable braking feel.

Which minibikes will this rear disc brake kit fit?

The kit is engineered for a wide set of minibike platforms using a 7/8" (22 mm) handlebar brake lever and a rear disc caliper with roughly 51 mm mounting hole spacing. It matches many popular 79–100cc models, but it is specifically a rear disc assembly, not a front caliper and not a drum brake.

• Compatible with Coleman Powersports CT100U and CC100X models.
• Fits Motovox MBX10 and MBX11 minibikes plus Monster Moto MMB80/MMB105.
• Also suitable for Baja, Doodlebug DB30, FR* GMB100 and similar 79–100cc machines.
• Verify rear caliper fit and disc-style brake requirement before purchase.

What hardware and dimensions are included in the kit?

The package contains a 7/8" brake lever, a 61" steel braided-style cable assembly and a rear disc caliper, plus brake pads and mounting hardware. Exact sizes are provided so you can confirm fitment and routing for your bike.

• Brake handle sized for 7/8" (22 mm) handlebars.
• Caliper mounting hole center-to-center: approximately 51 mm (2.01").

How does this kit perform and what materials are used?

Crucial moving parts are manufactured from durable steel to resist wear and maintain consistent braking force. The design aims for predictable lever feel and reliable clamping at the rear disc, while the supplied pads give immediate stopping capacity out of the box.

• Steel construction for lever, caliper and mounting hardware resists deformation.
• Pre-measured cable and sleeve reduce trimming and routing work.
• Four spare brake pads included for initial wear replacement.
• Basic tools in the box simplify the install process.

Who is this for: This rear disc brake kit is intended for minibike owners, mechanics and hobbyists who need a direct replacement or an upgrade on 79–100cc small-frame bikes that use a 7/8" lever and disc brake rear setup. It is not suitable for bikes that require front calipers or drum-style rear brakes. Buy it if you want a durable, ready-to-fit rear brake assembly with the cables and hardware needed to get back on the trail quickly.
