Premium Disc Brake for Pro3/Pro4 & MI3/MI4 Electric Scooters
High-performance CNC-machined aluminum alloy caliper with heat-resistant ceramic pistons for smooth braking and reduced fade. Precision-milled stainless steel rotor (140mm/160mm optional) ensures consistent stopping power even under heavy loads.

Ideal for urban commuters and delivery riders needing reliable downhill control. Includes pre-bled lines and universal mounting hardware for 10-minute installation.
