Electric Brake Hall Sensor Switch for Zoom & TurboBrake Hydraulic Lever

• Electric brake hall sensor switch suits Hydraulic levers of:
  • Zoom such as those on Kaabo models of Mantis & Wolf, earlier model Dragon Lightning (including V2), Dragon Slayer and most (the non-NUTT) models of VSETT such as 10+ & Zero such as 10X hydraulic models.
  • TurboBrake, such as HB427-H calliper models of:
    • Teverun (including models of Blade and Fighter).
    • Dragon / Langfeite models with on Predator, later models of the Cyclone Pro, Hurricane, Lightning & The Beast. See note regarding M6/M8 connector.
    • and of course eSN TurboBrake levers.
• Available in three variants, choice of M8 (8mm - most common) or M6 (Later models of Dragon Langfeite & InMotion):
  • M8 2-pin red male with 50mm cable - as Zoom Kaabo Factory Spare.
  • M8 2-pin red male with 300mm cable - as Zoom / TurboBrake Spare.
  • M6 2-pin red male with 300mm cable - as TurboBrake Spare.
• Mechanism uses magnetics with a two wire hall effect sensor, responsible for informing the controller of the position of the brake lever which activates electric braking and brake light. If problematic, electric brake and brake lights may not respond as expected when engaging brake lever, or the switch could be applying brake continuous or intermittently when lever is not engaged. To operate effectively, it needs be calibrated - see notes below. If calibration does not restore operation, and it fails continuity test on multimeter, replace the switch.

• Adopts the common convention used amongst nearly all eScooter makes and models being normally open. This means when lever is not engaged, the circuit is open ("off"). When engaged (pulled) the circuit closed (switch is "on"). Closer type.

Notes:

1. Switches needs be calibrated periodically as pads wear or brakes are serviced. Prior to adjusting or removing existing switch, ensure you backing off the grub screw that secures the connector.
2. The hall type switch uses magnetics therefore be mindful of the lever's proximity to other magnetic fields such as that from throttle. Close lever-throttle proximity can cause unexpected signalling - move or disconnect the throttle.
3. To troubleshoot, you can temporarily fit the switch from the other lever, check continuity with meter and check 5v is being delivered to it. Signal output of two wire IC's is via different current levels, a multimeter on continuity mode is usually sufficient test.
4. Note the newer Dragon Langfeite models (e.g. Predator, Hurricane and later models of Lightning & The Beast) use a smaller M6 connector plug. M6 is less common. We also stock M8 cables. There is no polarity applicable so it is a simple matter of joining each of the two wires and it is best practice to have some sort of plug so you can disconnect if necessary.
5. This switch appears similar to that on earlier (older) the Logan levers as both have a 6.2mm diameter. The notch/key on earlier Logan type is longer and narrower than this Zoom/TurboBrake type. The Logan variant is available here.
6. Refer to Kaabo Spares Category Home Page for wiring diagrams.
7. These videos demonstrate how to calibrate / replace (not Logan specific). It is best to just work on one side, over the course of several rides so it has bedded in prior to making changes to the other side. eSN recommends having the ebrake switch engage first (early) then as the lever is further depressed the physical pads engage. Allowing the electric brake to fully engage prior to physical brake pad engagement improves braking stability, reduces brake wear and reduces heat.
