01 / SENSOR CONNECTOR
Check Your 2-Pin Connector
If your scooter's original brake sensor connector matches our 2-pin plug and wiring, no extra sensor adapter cable is needed.

Choose the Right Braking System
Compare the key differences between standard mechanical brakes and the NUTT 2-piston hydraulic brake system.
Ordinary Brake
Standard cable-driven system
- Braking Performance: Slow response, unstable stop
- Sensor Feature: No power-off sensor, circuit risk
- Sealing Structure: Poor sealing, easy oil leakage
- Installation: Requires modification & adaptors
- Piston Structure: Plastic 2-piston, easy deformation
- Tube Length: Fixed tube length only
- Warranty: 6 Months short warranty
NUTT Hydraulic Brake
Advanced 2-piston hydraulic system
- Braking Performance: Sensitive & stable braking
- Sensor Feature: Built-in power-off sensor protects motor
- Sealing Structure: Leak-proof sealing, low maintenance
- Installation: Direct bolt-on replacement
- Piston Structure: 2-Piston CNC Aluminum Body
- Tube Length: Custom 1350/2200mm lengths
- Warranty: 1 Year warranty
Installation & safety
Installation Steps & Safety Instructions
Follow the fitment checks below before installing or riding with a NUTT hydraulic brake upgrade.
Confirm the correct configuration
Check the scooter model, production version, front or rear position, rotor side, mounting type and brake connector. Confirm whether a spacer, adapter cable or original washer is required.
Inspect the package before fitting
Make sure the caliper, lever, hose, brake pads and selected hardware match the purchased configuration. Do not install damaged parts or discard model-specific hardware before fitment is confirmed.
Remove the original brake safely
Secure the scooter before removing the original brake. Protect the rotor and hose area from contamination, and keep any original washers or model-specific parts for comparison.
Install the lever and caliper
Mount the lever and caliper using the correct hardware for the selected configuration. Keep the caliper aligned with the rotor and do not force parts into position.
Route the hose and check clearance
Route the hose away from sharp edges, moving parts and folding points. Check the gap around the caliper, rotor, fork, swingarm, tyre and other components before final tightening.
Test before normal riding
Check lever operation, rotor rubbing, bolt security and motor power cutoff. Complete a controlled low-speed test in a safe area before normal riding.

Hydraulic Braking FAQ
Everything you need to know about upgrading, installing, and maintaining NUTT hydraulic systems for a safer, smoother ride.
The Upgrade Experience
Why should I switch from mechanical to full hydraulic brakes?
Mechanical brakes rely on a steel cable that stretches over time, leading to a "mushy" feeling and frequent adjustments. NUTT Full Hydraulic Brakes use fluid to transfer power, providing:
- Effortless Braking: Stop with just one finger, even at high speeds.
- Consistent Power: No cable friction or stretch means maximum force reaches the pads every time.
- Self-Adjusting: As pads wear down, the hydraulic pistons automatically move closer to the rotor.
Will hydraulic brakes shorten my stopping distance?
Yes. Because hydraulic fluid is incompressible, the response is instantaneous. Most riders report a 30-50% improvement in stopping confidence and significantly shorter emergency braking distances compared to stock mechanical setups.
Universal Fitment & Compatibility
How do I know if this kit fits my electric scooter or e-bike?
You need to check three things:
- Mount Type: Most scooters use A-pillar (Post Mount) or B-pillar (IS Mount). Our kits include adapters for standard 140mm/160mm rotors.
- Hose Length: Measure your current brake lines. Our standard set comes with 1350mm (Front) and 2200mm (Rear) hoses.
- Electronic Connector: Check if your current lever uses a 2-pin (Red) or 3-pin (Yellow) waterproof Julet plug for the motor cut-off.
Are NUTT brakes "Open" or "Closed" systems?
NUTT uses an Open System with an integrated reservoir in the lever. This allows the system to handle heat expansion much better than closed systems, preventing "brake fade" during long descents.
Installation & Setup
Does the kit arrive pre-filled with oil?
Yes. All NUTT brake kits are pre-bled and factory-sealed. If your scooter has external cable routing, you can install them in 20 minutes without touching a drop of oil.
Tip: If you need to route the hose through the inside of a scooter frame, you will need to disconnect the hose and perform a simple "Top-up Bleed" after routing.
What tools do I need for installation?
Standard installation requires only:
- 4mm and 5mm Allen Keys (Hex wrenches).
- A pair of scissors or a utility knife (if you need to trim zip ties).
- Isopropyl alcohol (to clean rotors if you accidentally touch them).
Maintenance & Care
What kind of oil should I use for bleeding?
Use Mineral Oil only.
WARNING: Never use DOT fluid (used in cars). DOT fluid will corrode the seals in NUTT brakes and cause total failure.
How often should I change the brake pads?
This depends on your riding style, but generally:
- Commuters: Every 800-1200 km.
- Aggressive Riders: Every 500 km.
If the braking material is less than 1mm thick, it’s time for a replacement.
Common Troubleshooting
Why are my brakes squealing loudly?
Squealing is usually caused by contamination. Even a small amount of oil from your fingers or road grime can cause noise. Clean your rotors with Isopropyl Alcohol and lightly sand your pads to restore the friction surface.
The lever feels "spongy" and touches the handlebar. What happened?
This is a classic sign of air in the system. This can happen after a crash or if the hose was disconnected during installation. A simple "lever bleed" will remove the air bubbles and restore the firm feeling.
