Brake disc replacement advice

[zinomori]

Hello friends.
I would like to say thanks first for letting me be a part of this awesome forum. Well, I have Giant MPH Root hydraulic disc brakes (6 bolt 160mm discs) on my MBT. It seems I need to change the discs. Can I change the discs to any 6 bolt 160mm sized discs of other brands or do I need to buy Giant MPH Root specific discs? This is my first MBT, so I don't know much about it. So what do you guys suggest?

Thanks.

Any 6 bolt disk of the same diameter.
Giant does not make the brakes or the rotors. They just bolt them on.
Get a shop to do it for you. Did you bend yours? They last for years compared to the pads. If you have owned the bike long enough to need new rotors I might have expected you to know more about your bike than you indicate here. Of course you can bend a rotor on your first ride.
Rotors can also be straightened for minor warp.

Just a tip: If you are going into your LBS you might want to call them 'Rotors'

Of course it might be a second-hand bike, in which case the previous owner may have worn out (unlikely), bent (likely) or contaminated (likely) the rotors or pads (very likely)...

Just as a bent rotor can be straightened (use a shifting spanner), a contaminated rotor can be cleaned up using some fine sandpaper (or simply riding in filthy wet and gritty conditions). Contaminated pads might be resurrected by sanding/filing them back, but it's probably easier to throw them away and start fresh (make sure you clean/sand the rotor first!).

But don't ask why, because there isn't a good answer why many people seem to think bicycle disc brakes don't use brake discs.
