I've noticed my brake discs on 6 month old car are showing a bit of rust.
Is this normal? I have seen this on others cars but maybe slightly older.
What can I do to prevent it? :cry: :cry:
-
mine are risty whenever it rains,i thought this was normal :huh:
-
are you saying it's rusty when it rains and then clears up or is rusty because of the rain
it would figure the rain is causing it but my question is what's the end point, where does it all lead
how much is it gonna cost me :angry: :angry:
-
How can they be rusty in the rain and not in the dry? lol
If their rusty, their rusty .
-
that was my point!!! :embarassed:
-
Are you sure its actually rust and not just looks like rust with all the brake dust and all that jazz thats down there.
-
yeah it might be
it's deffo brown though
the brakes are okay
my point is really, will vw try to wangle some £Â£Ã‚£ out of me in the future
if so, i wanna know now rather than 2-3 years time or whatever :nerd:
-
yeah brake discs noramlly start to show "rust" at just the thought of getting wet, this is becuase its exposed metal.
you'll find that you'll get "rust" from just washing the car.
the "rust" disappears after you've driven the car though doesn't it?
-
the rust will dissapear once you drive and press the brake, or do you mean on the top of the brakes and not the face?? :huh:
-
it's not the brake itself but the part just inside the alloys
it's all metal...............
-
take a picture :huh:
-
fack man
i'm useless at taking photos and uploading
will have another look either tonight or over the weekend
my point is the motor is less than 30 days old and i want to catch the dealer on it if i can
when i mentioned it they said it's normal
my question is, it might be normal, but what are the implications?
-
I think its normal.. i noticed that mine had a couple of rust patches on it too the other day. Took it for a drive, came back and they were gone. Like someone said before its just exposed metal so it will rust very quickly.. but only on the surface.
-
brake disc's rust FACT, even the breaking surface rusts after the cars been driving in the rain. NOTHING TO WORRY ABOUT. cast iron always rusts, only very very lightly on the surface, brake discs are not make of stainless steel!!. Only area in the wheel department to look for is the hubs rusting which should not and a real problem on the Vw's and are covered under factory warranty.
-
cheers
i thought it was normal but wanted to check
-
The braking face of the disc will generally start to oxidise on any steel brake discs withing 8 hours of being exposed to water. It is simple chemistry. Once you are rolling again and you press the brakes it will go away as it is simply surface oxidation and not the deep seated rust you get on old Alfa's :grin: :nerd:
-
Do you mean the face of the disk or the bell. Take a look at this thread.

I took a paint brush to mine and gave them a coat of paint. (NOT the disk face of course :rolleyes:)
My MKiv the disk bells were spotless not a hint of rust, a friend at works are just the same on her Bora and thats three years old. VW must have changed the paint finish. :angry:
-
yeah like the photo posted by pns
not the calliper but the brake disc
-
i think u may mean wheel hubs,very common prob,i painted mine with red smoothrite,very close to same colour as caliper.
-
I was having a look at an 07 Audi S3 last week. Its hubs were just as bad.
-
My hubs started rusting after about 3 months. Just had 1st service done a couple of weeks ago and reported this. Unsurprisingly, Dealer said this was normal and as it didn't adversely effect the braking performance of the car, nothing would be done. I asked him to report this to VW as having rust on a relatively new car looked sh1t - big quality control issue IMO. Guess I'll have to get the smooth silver hammerite paint and brush out :undecided:
This seems to happen on all cars these days - mainly due to cheap iron in the disc construction and cost cutting during the manufacturing process. Have to say this didn't happen on my previous Boxster but the inboard brake disc surface rusted very badly and I had to replace all 4 discs twice in my 3 1/2 years of ownership (first set was done under warranty though :wink:)
