Rear Disc back plate rusted through

[WelshSue]

I have noticed that my N/S rear disc brake backplate has rusted through & flapping about. The O/S one is not as bad. Do they actually serve a purpose or can I remove them?

Quite a few . Protects suspention elements from heat, dust, water splashing etc

Just get a replacment , i cant imagine this being expensive

I agree with Piotr just replace it. Iv never heard of this happening though and my a6 has covered 328,000 miles!

Hello Susan,

Yes, it has to be replaced. The part is not too expensive as I recall, but I believe it is a main dealer part only. Should be available with a bit of discount by talking nicely in Welsh! 

Yes, these simply painted mild steel parts do rust and bits fall off them. Not uncommon, and it's usually the N/S goes first ad you would expect. 

Kind regards,

Gareth.

Thanks for the replies Guy's. I've had a look on the interweb. Seller on eBay had them for £59.99 for the pair, but thought I'd check elsewhere & found them on Amazon for £38.44 for the pair + £3.99 p&p. Should be here in the next few days. Looks fairly easy to fit(looking at Elsawin) Brake caliper off,Disc off, remove ABS sensor then unbolt hub.

Think the last one I had for the A3  via. Audi was a bit under £20 from memory.

Good  to know they are available as aftermarket parts for the A6.

Kind regards,

Gareth.

Took rear N/S wheel off yesterday to replace the splash guard. Couldn't get the Hub bolts off as completely seized on. What was left of splash guard fell off!! Going to take to local garage for them to see if they can get the bolts out.

Oh no! Not good! Hope it gets sorts quickly for you!

Hello Sue,

Well that makes the ones which I change on the A3 look pretty good! 

In the first photo, it appears to show a pair? of brake pipes clipped to the suspension arm. The nearest one seems to be rustier than you would like. Wondered if this has been carefully examined.

Kind regards,

Gareth.

Both pipes are fine,It was just a build up of dirt. Used a stiff brush then washed it off,dried & smeared with vaseline
