Hydraulic brake 3 pin sensors

[Wayners]

I've bought some hydraulic brakes with built in sensors for one of my bike conversions. Chinese brand so no spares or documentation. I didn't want to mess about with adding brake sensors to something like Shimano MT-200 as I've read it's better to get integrated sensors.

I have a 3rd build where I need to feed the pipe through the frame and may need new olives and cut pipe so I'm thinking I may need to get something with like the Shimano MT-200 for that purpose.
Are the stick on brake sensors ok?

Thanks

I have them on 2 of my bikes, was a bit of a faff getting it to work reliably, think I ended up wedging a washer in the brake lever arm to mount the magnet on to get the distance correct, not very elegant , but it works.

I've had them for a few years and they work fine. Called hydraulic brake sensors; I've actually got them on integrated gear/break shifters but the fitting would be the same.

I've used electric sticky tape for the magnet and double sided sticky tape for the sensor so I could easily adjust them, and remove if wanted. Turned out they didn't need any adjustment on the first fitting. The only issue was when someone carelessly lent a bike against ours and snagged the cable so the sensor fell off. If it had been properly glued it could well have broken the cable so maybe I was lucky.
