JOYOR Y8-S Brake Disc 120mm

The JOYOR Y8-S Brake Disc 120mm is a genuine replacement front or rear brake rotor designed specifically for the JOYOR Y8S electric scooter. It mounts directly to the wheel hub and works with the hydraulic or mechanical disc brake caliper to provide consistent, responsive stopping power. This 120mm diameter disc is engineered to match the original equipment geometry and mounting pattern of the Y8S.

Replace this brake disc if it shows signs of warping, deep scoring, excessive wear, or corrosion that compromises braking performance or causes noise and vibration during stops. Regular inspection is recommended—especially after heavy use or exposure to wet or salty conditions—as worn or damaged discs can reduce braking efficiency and accelerate pad wear.

This is a direct-fit, OEM-spec replacement part built to JOYOR’s quality standards for the Y8S model. No modifications required; installs using existing hardware and aligns precisely with the factory caliper.
