Need help d2 electrical issue

Hello all,
Wonder if anyone will be able to give me some suggestions on where to look next.
So got 3 amigos on the dash. I recently changed break disc and pads all round and still which needed doing. Anyway Plugged into diagnostics it came up with right abs sensor and air flow sensor.
Changed the right wheel bearing and new sensor. Plugged back into computer and still got that abs sensor fault even after clearing. The break disc becomes red hot after about a mile.
Any help would be much appreciated on where to go from this without having to take it to the garage

Sounds like the caliper is sticking on, setting off the ABS sensor and heating the disc. Or the other way round, heated disc setting off the sensor.

Hi, was the system power bled with that diagnostic tool? (what tool ?) anyway, as you have the 3 amigos on unplug the ABS modulator(maybe you'll get the red brake wearning too) and make a test drive like that... i'll tell more according to the result
