Clarks M3000 E-Bike Hydraulic Disc Brake Set – Motor Cutoff – 2-Piston – Front/Rear

The Clarks M3000 is a hydraulic disc brake system built for e-bikes that require integrated motor cut-off functionality. It combines dual-piston braking with an electrical sensor that signals the motor to disengage when the brake lever is pulled, improving control and safety on powered bikes.

Riders and shops choose the M3000 when they need a dependable, serviceable e-bike brake that integrates cleanly with common motor systems and uses mineral oil for straightforward maintenance.

Service / Ownership Context
Mineral oil brakes are lower maintenance than DOT-based systems but must never be mixed with other brake fluids. When shortening hoses, new olives must be installed and the system fully bled. Electrical connectors should be secured and routed to avoid strain or water ingress.

Fit & Use Signals
• A good fit for commuter and utility e-bikes with motor cut-off requirements
• Commonly chosen for hub-drive and mid-drive e-bike systems
• Works well for riders who want predictable braking and easy serviceability
• Not ideal for aggressive downhill or high-heat braking demands
• Not the right choice for non-e-bikes or motors without compatible cut-off inputs
