My A6 lives near you and has had two complete sets of disks in less than six years. Leave it outside and undriven for three weeks and you can guarantee irreparable disk damage. I try to drive mine at least once a week now for this reason.
This doesn't sound good. I wonder why they corrode so badly?

Grease the discs thoroughly every time you park. That should protect them from the salt sea air. NOTE: after doing this, drive the car with extreme caution. Indeed, don't drive it at all. If you use the brakes the grease will be removed and the discs will corrode.
|
Don't follow this, I'm afraid. How do you grease the discs, particularly the inboard surfaces.
Not driving it at all sounds like something of an inconvenience. Do you mean not drive it all [before removing the grease] ? How is the grease removed, other than by braking ?

I wouldn't try the grease idea! ;-)

OOps ! I guess I swallowed it hook, line and sinker.

Try using the stuff that you apply on the tyre wall to make them look new. I don't mean the black greasy stuff. I have sprayed this on all my tyres/wheels/discs. This prevent rust. You can buy it from Halfords in a spray can. I also finds that the brake dust will not stick to the alloy wheels, so it's greta stuff.
Hope this help.

I know for bikes there are Iron, Cast Iron and Stainless steel disks available. All at horrendous prices compared to cars - are SS disks available for cars in a seaside environment?
I know not to buy a car from the local seaside car auctions as they seem to rot at an amazing rate - but go very cheaply.

1)Take car to local backroad.
2)Accelerate to illegal speed.
3) Check rear view mirror. If clear, horse on brakes as hard as possible until car is stationary.
4) Repeat several times.
Rust gone. Total cost=$0

Changing discs and not the pads thats a recipe for disaster I cannot believe a main agent even suggested it.,Go to gsf the parts will be fraction of what Audi want and they are the same manufacturer.
|
4) Repeat several times.
And then report back that you're getting a vibration, which is no doubt caused by warped discs.

Disks & pads replaced by Audi @ £170 and the noise is still there.
Audi will take the car back in and were surprised when they were asked for a £170 refund - replacing rusting disks & pads in an 18mth car & only 14K did not fix the problem.
|
Sorry- thought the discs [and pads] were being replaced because they were rusty not because there was a grinding noise.
So you have got new discs [and new pads I hope?] and the brakes are still noisy? Weird- never come across that.Clean new pads and clean new discs - what causes the noise then?

I wasna fu but just had plenty.

I live about a mile from the Irish Sea, currently have a VW Bora (plus a wide variety of other cars over a period of 42 years) and never suffered from rusty brake disks.
I did once have a Vauxhall 1800 Magnum that developed distorted disks (had them skimmed by a specialist), but that has been the only type of brake disks problem.

Grinding noise diagnosed by Audi Dealer as rusty disks and they replaced diskd and pads but noise still there

I wouldn't go back to the Audi dealer in case they recommend you buy a whole new car ?!?

My old Legend lived first in Weston-super-Mare for nine years, then for five years outside, right by the beach on Portland - almost constant howling gales and flying spray. Never had any disc troubles. Surely it's down to quality of the metal? An upmarket badge presumably doesn't guarantee up-market materials.
|
|
"Never had any disc troubles." Possibly neither has the Audi! Have they still got the parts? If so the "rust" can be examined. As the noise was not fixed by the apparent confidence trick, the cause of the noise needs tobe established, and a refund made if unconnected. You pay enough of a premium to expect competence, surely.
|
|
Grinding noise from rusty discs usually only happens during braking. Is the grinding there all the time - or just when the pedal is pressed? If its there all the time then it could be any number of things including wheel bearings. I'm surprised that the garage got this diagnosis wrong...
|
So whats the problem with the discs rusting after being wet from rain or washing.
Just imagine what they look like when they are stored in a compound for weeks/months without any movements, the only shiney part is where the disc pad covered the disc.
Don't say the dealers clean the discs before delivery, cause they don't, only a road test with braking to clear the disc, unless it really excessive where the vehicle stood in water covering part of the disc.
|
|
After a few days parked in filthy salty roadmist and smog, the thing will graunch most of the way round a long block, driven fairly gently. If it still makes noises after that, look more closely, and be ready for barked knuckles and stuff.

Did you get a refund? I'd love to have seen their faces when you asked!

In years gone by when nasty stuff like asbestos was allowed in brake pads then discs could be made with of a fairly corrosion resistant steel and would normally last as long as the car, the pads being the consumable item. Nowdays for good reasons pad material has changed and discs are also considered to be a consumable, 60k ish for front discs is normal as is corrosion when they are not used.
