XTECH HB100 Hydraulic Brake Caliper — Aluminum Alloy for Xiaomi M365 / 1S / Pro / Pro 2 (Works with 110 / 120 / 135 mm Discs)

Upgrade your Xiaomi scooter’s stopping power with the XTECH HB100 hydraulic (semi-hydraulic) brake. Built from lightweight aluminum alloy, the HB100 delivers stronger, smoother braking than stock mechanical calipers. Compatible with M365, 1S, Pro, and Pro 2 when paired with the correct rotor size and mount/bracket.

Key Features

• Hydraulic assist caliper (HB100): powerful modulation and shorter stopping distance than stock.
• Aluminum alloy body: light, rigid, and corrosion-resistant.
• Disc size support: works with 110 mm and 120 mm rotors (120 mm recommended for better performance). 135 mm fits Pro/Pro 2 only (not M365).
• Model-specific fitment: designed for Xiaomi M365 / 1S / Pro / Pro 2 with suitable mounting bracket and rotor.
• Color options: Black / Red / Blue / Purple (see images).

Compatibility & Disc Size Notes

• M365 / 1S: Use 110–120 mm rotors. 120 mm generally provides better braking.
• M365 Pro / Pro 2: Use 110–120 mm rotors, or 135 mm with the correct bracket/clearance. 135 mm is not compatible with M365 (non-Pro).
• A mounting adapter/bracket and longer bolts/spacers may be required depending on rotor size and fork/swingarm tolerances (not always included).
