While it's a part check the thickness of the rotor. 11mm is the minimum.
Get good quality pads. FF or FG friction rating. Stopping ability is more
important than long life.

Got into it today and pulled out the pads and gave it a clean. It certainly
was a bit crusty in there and the pads took a lot of gentle tapping to get
them out. What I presume is the silencer plate was pretty torn up - much of
which probably happened as I was pulling it out. It was definitely the
calliper, as the wheel spins easily without the pads in.

I sourced a rebuilt one at $108 with a core swap (at Lordco - anyone in BC
have an account name I could use?) which is great since I can do it as soon
as I get over to the mainland.
