Clarks SYNC-2E Hydraulic Disc Brake Set – E-Bike Motor Cutoff – 2-Piston – Front/Rear
The Clarks SYNC-2E is a hydraulic disc brake system designed specifically for e-bikes, combining dependable stopping power with motor shut-off integration for added safety. It uses a 2-piston caliper tuned for smooth, controlled braking rather than abrupt on/off feel.
Riders and shops choose the SYNC-2E when they need an e-bike-rated brake that works cleanly with motor systems, is easy to set up, and remains serviceable over time using mineral oil.

Service / Ownership Context
Mineral oil systems are low maintenance and less corrosive than DOT fluid but should not be mixed with other brake fluids. Hose shortening requires proper installation of new olives and a full bleed. Motor cut-off wiring should be routed carefully to avoid strain or interference during steering and suspension movement.
Fit & Use Signals
• A good fit for e-bikes that require brake-activated motor shut-off
• Commonly chosen for commuter, cargo, and utility e-bikes
• Works well for riders who want predictable braking over outright bite
• Not ideal for riders seeking high-end downhill brake power
• Not the right choice for non-e-bikes or systems without motor cut-off compatibility
