CILOYU Mini Bike Rear Brake Kit for CT100U GMB100 — 7/8" Lever, 61" Cable, 51mm Caliper Mount

CILOYU Mini Bike Brake Lever Cable Kit is a full rear brake assembly that includes a 7/8" lever, 61" cable, rear caliper and two pads designed for CT100U/GMB100-style minibikes.

This compact brake kit supplies the parts needed to restore or upgrade a rear braking system on many small-displacement minibikes and go-karts. The components are built from steel and abrasion-resistant cable materials and sized to fit 7/8" handlebars and a 51 mm caliper mount spacing. Check frame and handlebar dimensions before ordering to ensure compatibility with widened frames or high-rise bars.

Will this kit fit my Coleman CT100U or similar minibike?

Compatibility covers a wide range of minibike models, including CT100U and many Coleman, Baja and Motovox machines. The lever is sized for 7/8" (22 mm) handlebars and the caliper uses a 51 mm mounting hole distance, so confirm those dimensions on your bike.

• Lever size: 7/8" (22 mm) handlebar clamp
• Cable overall length: 1550 mm (61") with 55" sleeve
• Caliper mounting distance: 51 mm (2.01")
• Designed as a rear brake caliper — not a front version

How durable and durable is the cable and hardware for regular use?

The brake cable is built with abrasion-resistant wire rope enclosed in a protective rubber sleeve for longer service life under typical minibike use. Steel components on the lever and caliper offer strength and resistance to routine impacts and vibration common with off-road riding.

• Cable construction: steel wire rope with rubber jacket for abrasion protection
• Caliper and lever: durable steel construction
• Brake pads: replaceable pair included for maintenance
• Suitable for normal recreational and trail riding conditions

What exactly comes in the box and what should I measure before buying?

The kit ships with everything required to replace a rear cable-actuated brake: lever, full-length cable, rear caliper and two brake pads. Before purchase, measure your handlebar diameter, available cable routing length, caliper mount spacing and confirm you need a rear rather than front caliper.

• Included: 1 x 7/8" brake lever, 1 x 61" brake cable, 1 x rear brake caliper, 2 x brake pads
• Measure: handlebar diameter (22 mm), caliper mount spacing (51 mm), usable cable routing length
• Check: widened frames or nonstandard mounts may prevent fit

How easy is installation and what tools will I need?

Installation is straightforward for anyone familiar with basic minibike maintenance: attach the lever to the handlebar, route and secure the cable, mount the caliper to the brake plate, and adjust pad clearance. Typical installation requires common hand tools and minor cable tensioning to set brake bite.

• Common tools: wrenches, pliers, cable cutters, screwdrivers
• Adjustment: set cable tension and pad clearance for smooth operation
• Tip: inspect brake mounting points and clean threads before installing

Who is this for: This CILOYU brake kit is intended for minibike owners, mechanics and hobbyists restoring or maintaining CT100U, GMB100 and similar small-displacement minibikes who need a complete rear brake replacement. It suits anyone looking for a ready-made steel lever, a long 61" cable, a rear caliper sized to 51 mm mounts, and two replacement pads, provided the bike’s frame and handlebar geometry match the listed dimensions.
