JOYOR S5 Brake Disc 120mm

The JOYOR S5 Brake Disc 120mm is a genuine replacement front or rear brake rotor designed specifically for the JOYOR S5 electric scooter. It mounts directly to the wheel hub and works in conjunction 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’s mounting pattern, thickness, and surface finish for optimal brake performance and longevity.

Replace this brake disc when it shows signs of excessive wear, deep grooves, cracking, warping, or severe corrosion — all of which can reduce braking efficiency and cause noise or vibration during stops. Regular inspection is recommended, especially after heavy use or exposure to wet or salty conditions, as disc wear impacts overall brake system safety and responsiveness.

This is a genuine JOYOR OEM part with precise dimensional and material specifications for the S5 model, ensuring direct fitment without modification and full compatibility with the factory brake caliper and mounting hardware.
