rust on brakes

Welshbigman · 13-12-2007, 20:48

having had my car approx 3.5mths and covered 7k in it, there is now rust apearing on the brake disks (the area sprayed silver)
Popped down to my dealer about lunchtime, he was busy but got one of the mechanics out to look at it
The mechanic informs me that it was not a mechanical issue (which i already realised) he seemed very blase when I informed him it shouldn't happen after 3months, but did agree that it did give a poor visual impression.
As the dealer was busy he said he would ask his opinion and they'd be in touch

Has anyone else come across this problem???

in my opinion for rust to apear this quick they were either painted rusty, not preped properly, or not enough paint on, or a combination of all 3

The silver on the discs is a zinc rich coating called Geomet - see http://www.metal-coatings.com/mcii/pdf/GEOMET.pdf - its good stuff but brake discs are a very harsh environment because of salt spray and the temperature range. Most standard coatings will burn off over time.

The cast iron discs are factory coated, and unless you can prove you have duff ones, I doubt the dealers will assist.

I had a Ford Focus before the Octavia and the discs weren't coated at all, and rusted loads.

My last Octavia suffered this problem after about 3 months. Didn't bother to do anything about it as my dealer would have said "bog off".

My current one is OK after 4 months but i'll keep my fingers crossed.

My Mk1 didn't do it until the rear discs were replaced at about 80,000 miles but the ones fitted were NOT OEM discs (bloody lease co.!) and they rusted up pretty quickly.

Welshbigman · 13-12-2007, 22:10

maybe its me being fussy then. But to me its a coating/paint which is covered by the warranty????
My boss had a similar problem with his Audi

dstev2000 · 13-12-2007, 22:20

Don't get me wrong I think it looks crap when they go rusty.

If you speak nicely to your dealer they might well do something about it for you, a few members here have managed to get it sorted.

gadgetman · 13-12-2007, 23:00

Dad never has issues on any of his cars*.

All my cars have been ownd for 3 years before swapping.

Clio RSI suffered from 50k* Was fathers before, swap from 30k(ish)
Mazda 626 from around 10k, fronts changed @ 50k and was fine upto 70k (looked cr@p with the backs still affected

)
Mk1 Octy 1.8T Elegance from new upto 40k

Mk2 Octy Elegance?????? 9 Months old so far, and 8k

*crosses fingers*

Mine are still virtually rustless after approx. 20months, but it was one thing I spotted on the demo when I picked mine up.

Makefish · 14-12-2007, 10:00

Has been covered before as it's quite a common issue. Some have managed to get their dealers to sort it but I did my own wit a tin of silver Hammerite.

Previous thread here with piccy's

woodenspatulas · 14-12-2007, 10:39

never had a car that didnt have this issue. after all the brakes are there to stop you first, looking nice isnt really a consideration.

on my car ive hammerite'd them and after about 3 months they are like it again. even high temp paint dosnt last!

i think its just as has been said that the brakes are in a very harsh environment and its probably impossible to get them looking good without affecting the braking

sworrall · 14-12-2007, 21:38

have seen a few others mention this one here, some have had the dealers paint them and others had the dealers fob them off so results seem quite mixed. mine have held up quite well and havent rusted at all and its two years old now.

I was in the dealers today to get my sensors checked and notcied that the (7 miles on clock) new L&K on display had what looked like rusty centres! (might have been mucky dried water though)

A hell of a way to showcase the L&K then

Standard equipment includes: Xenons, Leather seats, rusty brake discs.........

sibart · 14-12-2007, 22:05

Mine went within a month, most of the time wheels are spinning to fast to notice

cheezemonkhai · 15-12-2007, 00:53

Somebody on her has used EBC disks with a black coating.

If you can find the thread it might be worth asking if they are still looking good or if the rust has come through.

bosnjo · 15-12-2007, 11:15

Mechanicaly speaking, there is nothing to worry about, disks will last ages before rust destroys them. Usualy, they get worned long before that. But, as I worked as mechanic 20 years ago, I've seen cars 15-20 years old, driven a little by old people, with original disks on. (At that time there were no many cars with disks). Those disks were full of rust but still operational. So, mechanicaly, no worries.
Now, visualy, that's the other story. You can always clean them well (very well) and then buy a paint, silver, gray or black, extreme temperature resistant, and give it a touch.
As for me it's not a problem, I didn't even look at them yet, 15 months old Octy.

i have to say thats not uncommon. end of the day the dealer would have to pay for a tech to take the wheels off, to let a paint guy paint them up, then have the tech put the wheel back on!

its like the "how many people does it take to change a......." question

it odd how it doesnt happen to them all though. id have thought if they were all the same disks with the same coating then it would affect them all the same. maybe its a manufacturing thing.

Ciderspace · 17-12-2007, 10:55

My vRS is 2 weeks old and there is some minor rusting!

This could come down to the "Who can give us the part to spec cheapest this week" model of supply that some companies use.
