ZTZ MTB Hydraulic Disc Brake Kit — 2-Piston eBike Brake Pair with 160mm Rotors, 950/1880mm Hoses, Power-Cut Sensor (Black)

ZTZ MTB Hydraulic Disc Brake Kit is a complete two-piston hydraulic braking system for e-bikes and bicycles, supplied with 160mm rotors and power-cut sensors for safer riding.

Designed for mountain bikes, fat bikes, folding bikes and electric bicycles, this ZTZ kit provides even dual-sided braking pressure through 2-piston calipers, adjustable levers, and factory-fitted hoses (950mm front, 1880mm rear). It ships as a pair with rotors and a detachable 2-pin power-cut sensor that interrupts motor output when the brake engages. The system aims to increase stopping force and pad life while fitting a wide range of modern bike builds.

How does the two-piston caliper improve braking performance?

The dual-piston arrangement pushes pads evenly from both sides, reducing uneven wear and increasing effective braking force compared with single-piston designs. That balanced contact promotes longer pad life and a more consistent pedal‑to‑stop feel under load.

• Dual-piston oil pressure for balanced pad engagement
• Estimated 30% increase in braking force versus comparable single-piston units
• Pad longevity improvement through even wear distribution

Will these brakes fit my electric bike and how are the hose lengths configured?

The kit includes a front hose of 950mm and a rear hose of 1880mm—common lengths for many mountain and e-bike frames. Before ordering, measure routing needs on your frame and compare connector types to ensure the hoses and 2-pin sensor plug reach and match your bike’s wiring.

• Front hose: 950mm (37.4 in); rear hose: 1880mm (74 in)
• Suitable for mountain bikes, fat bikes, folding bikes, e-bikes, scooters
• Confirm your frame’s hose routing and connector compatibility before installation

What safety features does the ZTZ kit include for e-bike integration?

An included detachable power-off sensor detects braking and sends a cut-off signal to the motor to reduce power during braking. The sensor uses a 2-pin waterproof connector for reliable outdoor use—check that your e-bike controller accepts the same plug and signal type.

• Removable power-cut sensor for motor interruption during braking
• 2-pin waterproof connector for weather resistance
• Sensor can be tested and fitted or removed depending on controller compatibility

How should I install and maintain these hydraulic brakes?

Proper installation calls for steady alignment of calipers and pads to the rotor, bleeding the hydraulic system to remove air, and fine-tuning lever reach and pad clearance. After setup, confirm that the lever contacts the disc correctly and re-check fittings and hose routing periodically for safe, consistent performance.

• Align calipers and pads to eliminate rubbing and clicking noises
• Bleed the system to purge air and preserve braking responsiveness
• Adjust lever spiral function for personal reach and comfort

Who is this for: The ZTZ MTB Hydraulic Disc Brake Kit suits riders upgrading from mechanical or single-piston hydraulic brakes, e-bike owners seeking a motor cut-off safety sensor, and cyclists who want stronger, more durable stopping power across trail, urban, or mixed-terrain rides. It’s ideal for home mechanics and bike shops comfortable with hydraulic installation and bleeding, and for anyone who has verified hose length and connector compatibility with their frame and controller.
