Hi my name is***** am a diagnostic technician and look forward to working with you.The ABS fault and hot brake disc ultimately will not be directly related. Firstly, the hot brakes are a sign of one of the caliper sticking. It is very common for either the pads, sliding pins or caliper piston to stick causing the brake to bind on and generate excessive heat. The front brakes need to be stripped and inspected, often it is simply a case of cleaning up the seized parts and re-greasing, worst case a new caliper may be required, the discs and pads should also be inspected after binding and replaced if necessary as the heat can warp discs and crack the pads. If the hub got excessively hot as a result of the binding it could have caused damage to the ABS sensor, This is the only way i can imagine the two faults would be linked.Unfortunately with regards ***** ***** ABS light, it is a little more difficult to diagnose as there are four sensors which consist of two parts (sensor and reluctor ring) as well as an ABS Pump, control unit and pressure sensors. The fault could be related to any one of these components and although it is almost certainly a simple case of replacing a sensor, it is difficult to know which one so the next step once the brakes are inspected is to have a diagnostic scan carried out (any good garage will do this for around £40) This will give a fault code and description of the fault which pinpoints the problem. Please feel free to ask if you have any further questions, if your happy with my answer please don't forget to provide a rating, thanks, Ross.
