JOYOR S10-S Brake Disc 120mm

The JOYOR S10-S Brake Disc 120mm is a genuine replacement rotor designed specifically for the JOYOR S10S electric scooter. It mounts to the front or rear wheel hub and works with the hydraulic disc brake caliper to provide consistent, responsive stopping power. This 120mm diameter disc is engineered to match the original equipment’s mounting pattern, thickness, and surface finish for optimal brake performance and heat dissipation.

Replace this brake disc when it shows signs of excessive wear, deep grooves, warping, or cracking — typically after prolonged use or following brake pad replacement if the disc is scored or no longer within minimum thickness specifications. Regular inspection helps maintain braking efficiency and rider safety.

This is a direct-fit JOYOR OEM-spec part, manufactured to exact tolerances for the S10S model. No modifications or adapters are required for installation.
