GY6 Rear Brake Arm Spring

Rear Brake Arm Spring for GY6 150cc and 125cc Scooters

This spring is made for GY6-engine scooters in the 150cc and 125cc sizes. It sits within the braking system and helps the brake mechanism work as intended. Like other GY6 scooter parts, it can be swapped out without much difficulty to keep your scooter running well. If you see signs of trouble such as a warped rotor or leaking calipers, it's worth replacing this spring soon.

What This Part Does

In the braking system, the rear brake arm spring helps bring the brake mechanism into action when you apply the brakes. When braking feels off, swapping in a new spring can bring back normal operation and support safer stopping.
