Rear Mechanical Disc Brake Caliper
The caliper uses a ball-ramp cam system to translate cable pull into axial pad pressure. If the internal return spring fails or the pivot arm binds due to environmental contamination, the pads will not retract to their neutral position, causing constant friction against the rotor.

140mm Rear Brake Rotor
Mechanical disc systems on e-scooters have very tight tolerances. If the steel rotor develops lateral runout (warping) due to heat cycles or impact, it will intermittently or constantly strike the brake pads regardless of caliper adjustment, manifesting as a dragging sensation.

Brake Cable and Housing Assembly
The brake system relies on the caliper's return spring to overcome the friction of the entire cable run. If the inner wire is frayed or the housing liner is compromised, the friction prevents the cable from sliding back fully, leaving the caliper partially engaged.
