No worries about rust, but in long term removing wheel will become difficult by rust around area that wheels touch the disc. You could take it to some shop and they will clean the discs and paint them with high temperature resistant paint. Silver or black. You won’t see rusty disc anymore. 

Mid you do that, do it for rear drums too.

Don’t forget to mention the shop to apply apply some silicon (not too much of it) high temp grease to the area that wheel touches the disc before put the wheels back.

You don't put anything on wheel hub facings, there is no need..When you take the wheel off, road dirt wheel inevitably stick to it and you will have more problems. I have never had trouble removing wheels, brake drums yes...

We used to have problems with Ford escort and Vauxhall astra van front wheels becoming stuck on if they were'nt copper coated
Long time back but every now and then they would be as tight as hell

Just a habit of mine now

As for the discs, yes more rust than normal and probably as mentioned been cleaned with a brake cleaner so pulled all the oil out making then look worse than normal
Paint them......

Off topic, but relevant.

Rust is more annoying on a cast iron frying pan as the taste gets on the food. Yuk.

Always wipe it with a thin coating of oil after washing.

so should I put some oil on my brakes ?  ...........????????

Just make sure they don't put any oil or silicone grease  on the wheel studs, unless you want the 'excitement' of watching one of your wheels overtake you as your car starts a slow lean to port or starboard.

What ?...

Bedding in the brakes does not harden the brake rotor.

Nonsense! Cars today need no running in of any kind.

Perfectly normal for cast iron disks.

It's the fault of the Mag wheels, specifically the large gap between the spokes on the wheels, (more visual) with normal pressed steel wheels you would not notice it as the holes are much smaller.

Painting is not recommended as the heat from the disks will cause it to smoke and/or burn off.

It's not "the fault of the wheels"!  It's the fault of the chemical reaction between water, oxygen and iron, and, regardless of the wheel design, it happens to every cast iron/ steel disc brake.

 

"Painting is not recommended as the heat from the disks will cause it to smoke and/or burn off".

Who doesn't recommend painting the non-braking surface?  Heat-resistant paint is designed for that purpose, amongst others and will not smoke or burn off!

My wife bought a new Isuzu truck and last thursday was delivered to us. 

Enter the VIN number into a web-based VIN decoder and see how 'new' your new truck is. It could have been sitting around a factory parking lot for a while before it was delivered? Isuzu assembly is either in Samut Prakan or Chachoengsao so could be a sea air and/or humidity issue rather than a flooded parking lot.

They are never painted and should not be,even heat resistant paint could cause a fire ! Rotors get very hot! this is very bad advice and your post should be removed.  

Strange my stick on plastic caliper goodies haven't gone up in smoke eh...

As a previous owner of a transam....I don't believe you ever put those on your los ride 555

Actually the Trans stock brakes had a <deleted> single pot caliper, so I replaced them with Wilwood 4 pots, bit like below....

If you Grease them real good they will not rust.

 

Just on the outside chance someone takes this reply seriously, Please don't grease your brakes,

I was only joking.

Grease on the brakes will affect the stopping distance of your vehicle.

My wifes family own a Isuzu from 1998 and have never had rust on any of the brakes

They operate a mechanics and have never heard of this

I think it is safe to say you have bene conned - phone isuzu and report the dealership go to corporate office and put everything on social in all isuzu groups I believe you have been done my friend

Never had any rust after over a decade of using our isuzu and it went through the floods this is total nonsense

The other posts here about putting oil on disc brakes are just nonsense I've worked in the auto trade since a young man you have been sold a defective product possibly imitation from china take it to a big isuzu dealership they will tell you whats what.

Just checked the brakes on new isuzu are anodised and painted with anti rust so although you were told the truth its not what u have in reality

As mentioned here check the VINs as you may been sold a cut and shut - look for weld marks around the door frames that seem odd

But first call isuzu head office and talk to a professional who is working in the actual licensed isuzu center not someone claiming to be isuzu there is a big difference 

These vehicles are good for 20 years or more with proper service intervals there is no way you should have rust on a new car man that is horse<deleted> my friend they are having you for a fool

Street or track version ?

No idea, it was a long time ago, ordered through a Wilwood agent in England. A complete alloy front hub/bell/rotor/bearings/caliper conversion kit... To be honest the brakes were not much better, so I went to a performance brake workshop which found in their stock a wider discs, but they had to machine up bells to match, and I had to make caliper brackets to move the calipers outwards. All good fun though, and the brakes were better...

No, the rotors are squeaky clean, over clean....Why do you think replacement rotors have a compound of some sort and perhaps waxed paper to stop cast iron rust..

Mine never had piston gaiters...There was no room for them either, when all assembled the pistons were flush with the caliper face..
