puzzled!! had front brakes changed 4 mths back , then short while back wear indicator appeared! took it in and rear done , so all must be ok ! nope , still had wear indicator ! eventually replaced all sensors and gues what still have damn wear indicator! I thought it should automatically reset but it hasnt so anyone ideas as to the potential fault. Btw had bulb failure end last week and new bulb reset indicator so not a main system error!
 
The loom at the rear (for the pad warning) chafes on the suspension arms. Take a look with the wheels off.
 
no wear shown

have checked , with wheel off but cant see any sign of wear or abrassion to cables , any other ideas please guys?
 
Check the wear sensors again. Is there a brake in the wires?
 
wear sensors

all 3 , 2 front and one rear have been replaced! so doubt if a faulty one has been replaced by another faulty one!
 
You never know. Check them with a meter.

If they are ok the rest of the wiring needs to be checked.
