Replace the braking assembly you need with a Strike Shadow brake set from Strike Cycles. The front option is a full, pre-bled set with a right-side brake lever for the Shadow 60V. The rear option is a full, pre-bled set with a left-side brake lever.
Pre-bled hydraulic systems arrive filled with fluid and bled to remove air, helping simplify installation. Keeping the hydraulic connections sealed during fitting helps preserve that preparation. Check mounting, lever feel, and brake operation before riding.
