Opinions re Norco Bush Pilot components?

[Sir Ridesalot]

Hi all. I am thinking about buying a Norco Bush Pilot mtn bike msrp
$539 Cdn.

I live in a small town in Ontario, Canada.

Could some of you advise me on the quality and the durability of the
components found on this bicycle. The bike is at the upper limit of my
budget so please don't say "Buy this other one at $800."

I am most concerned about the disc brakes and whether they will stay in
adjustment, perform well and last a while.

All useful advice is greatly appreciated.

Peter.
