E-brake sensor
This is the sensor and wire that goes between the e-brake lever and the battery gauge and IT DOES NOT INCLUDE THE LEVER. In fact there are no metal parts on it except a little screw. It is the part that does the electrical function of turning the motor off when the brakes are engaged. It is screwed onto the e-brake lever with a small Phillips head screwdriver. The other end is a two pin connector plug that is plugged into a socket mounted on the PCB inside the battery gauge.
This parts comes with the purchase of a pair of e-brake levers. However, you only need this part, the sensors, not the levers, if your e-brake levers are malfunctioning electrically. You don't need these if your e-brake levers have mechanical issues such as poor braking power. How can you know? The controllor has a self-diagnostic LED that blinks three times if the throttle is off or if the e-brakes are engaged. If the throttle is on and you are not touching the e-brake lever and there is nothing causing the brake lever to be depressed by itself (such as a broken brake cable or sticky brake arm) then there is a chance that your e-brake is malfunctioning electrically. Simply unscrew the e-brake sensor from the underside of the e-brake lever. If the controllor stops its blinking and shows the solid red light, then the e-brake sensor needs replacing and you need to order this product that you are currently viewing. For your $20 you only get 1 of these sensors.
Removal of the e-brake sensor does not require any specific tools and can be attempted at home. Having said that, it's not an easy task and if the battery gauge becomes damaged in the attempt then it has just become a bigger task! Get your dealer to do this if you're not interested in becoming acquainted with the finer aspects of eZeebike design! Still want to try it? Here's how:
- Take a photo of what it all looks like (where the cable ties are, how the cables bend before entering the battery gauge etc)
- Use a small screwdriver to remove the e-brake sensor from the e-brake lever
- Clip the cable ties restraining the cables entering the battery gauge
- Remove the twirly black cable wrapping between the e-brake and the battery gauge and any cable ties
- Remove the small screws from the battery gauge and put them somewhere safe
- Carefully pull apart the battery gauge until you can see the insides. Note the white plastic sockets mounted on the PCB. This is where the e-brakes are plugged in.
- Use a small blade or pin or something pointy and sharp to break the glue holding the e-brake connectors in.
- Unplug the suspect e-brake connector.
** At this point it is a good idea to plug the new sensor straight in and screw it into the e-brake lever to confirm that replacing it will actually fix the problem!**
- Here's the hard part - remove the suspect e-brake connector by pushing it through the grommet that is holding all the other wires that go into the battery gauge. If you can't do it you can always cut it off but that won't help you in the next step and will also ruin the suspect part, which might be handy for further troubleshooting or if you want to claim the part on warranty.
- Now do the reverse. You have to push the new connector through the grommet and plug into the PCB. Don't do any gluing yet!
- Screw the e-brake sensor into the e-brake to verify that you've fixed the problem
- If you have a glue gun or some glue, glue the e-brake connector into the socket on the PCB. If you don't have glue don't worry about it, it will be fine.
- Put all your cable ties and screws and curly cable wrap back into place
- Pat yourself on the back, brag about your achievements to friends and email us your CV.
