Magura MT4 eSTOP Hydraulic Disc Brake – No Motor Cutoff – 2-Piston – Black/Silver

The Magura MT4 eSTOP is a hydraulic disc brake designed for modern e-bikes that do not require a motor cut-off switch. It delivers controlled, predictable braking for higher-weight bikes without integrating any electrical shutoff, making it a clean replacement option when a cutoff is not needed or not supported by the motor system.

Riders and shops choose the MT4 eSTOP when they want a high-quality, serviceable Magura brake with strong modulation and low weight—without adding electrical complexity.

Compatibility & Use Notes
• Designed for e-bikes and non-e-bikes that do not require motor cut-off
• Sold as a single brake (can be used front or rear)

Service / Ownership Context
Because this brake does not include a motor cut-off, it is best suited for systems where braking does not need to communicate with the motor. Hose shortening requires proper fittings and a full bleed using Magura-approved mineral oil. Lever reach should be set during installation to match rider hand size and braking preference.

Fit & Use Signals
• A good fit for e-bikes that do not require brake-activated motor shutoff
• Commonly chosen as a clean replacement for worn or damaged brakes
• Works well for city, touring, and mixed-surface e-bike use
• Not ideal if a motor cut-off switch is required by the drive system
• Not the right choice for downhill or gravity-focused riding
