Recommended Maintenance Items Pinned Electric recommends keeping the following service items on hand with your Formula eMoto Brake System: Formula eMoto Brake Bleed Kit – Recommended for routine brake maintenance, fluid changes, or removing air from the hydraulic system. The Formula eMoto Brake System uses DOT 4 brake fluid. DOT 4 brake fluid is not included with the bleed kit. Formula eMoto 4-Piston Sintered Brake Pads – Keeping an extra set of replacement pads on hand helps ensure you're ready when your existing pads become worn or contaminated. Formula Light E-Moto Replacement Brake Lever – A direct replacement for the original Formula Light E-Moto brake lever. Ideal for replacing a damaged, bent, or worn lever without replacing the complete brake assembly. Pinned Electric Tip: Brake pads are a wear item, and hydraulic brakes may eventually require bleeding or fluid service. Having both a compatible bleed kit and replacement pads in your toolbox can help minimize downtime and keep your Formula eMoto brakes performing properly. Important Notes Pinned Electric recommends confirming your fork, rotor size, rotor thickness, and mounting configuration before ordering. The caliper is compatible with brake rotors up to 3mm thick. The DOT 4 system provides improved temperature control and consistent braking performance during demanding use. Sintered brake pads provide excellent durability and braking performance under heat and aggressive riding conditions. Replacement Formula eMoto 4-piston sintered brake pads are available separately.
