Hi guys. Normally have an issue after about 5-10 minutes of driving. When coming to a stop the noise start to appear at around 20km/hr. My last service was told that my discs need machining however the noise sound more mechanical like a grinding diff or something. About 180,000 ks on the clock
 
It sounds like you need new brake pads to me. And if it's gone on for a while, you may not be able to machine the rotors either. But I'm totally guessing here.

I would check pads and rotors.

You may also have a pebble or something stuck on a pad, I've had that happen once.
