Rear Brake Disc Wear
« on: 02 May 2017, 17:08 »
Just put my 2 year old Gti DSG in for its second service and been told the rear pads and discs are 90% worn! It's only done 11,844 miles since new. I'm not a heavy braker and no warning light is on. Anyone else had this issue with low mileage?

If I'm honest the fronts always go first on all my previous cars? The rears normally need replacing as they seem to get scored/corroded....

My wife's R had a similar issue with her R after 15k and less than two years old with fronts fine, ironically my R had less wear and had been tracked and done more miles

Rear brakes are used by ACC (it only uses the rears) and I believe its also used for ESP...

The discs shouldn't be worn though, the only time they get seriously damaged is if the pads are down to the metal...

ACC has been used about twice on my wife's as she does not know how to use it

Sounds a bit fishy IMO.

I'd get the dealer to show you the wear in person or at least see it on the service video most of them send out. After 25k I've one rear that's a bit scored but otherwise they are barely worn.

This. Usually one goes through at least two sets of front pads before changing the rears.

The ACC uses all brakes not just rear. I have noticed the rear rotors on MK7s get scored quicker than in other cars. Not sure if the ebrake has anything to do with it or the stability control which uses the brakes on the rear to keep the car under control when going fast in a corner.

I recon they are saying that because your rear brake hubs are corroded and they think you will fall for the 'look sir your brakes are worn, you can see how they look' line. If they were 90% worn then surely you would be able to see it. Plus there might not be ware connectors on rear pads, mainly because the fronts always go first and that warning will make you check them or go to a garage to have them checked.

If you aren't confident enough to check for yourself then take it elsewhere for a second opinion. I'd be highly dubious though for reasons given already and if right would be concerned that the brakes were binding. My previous car which a friend now owns is now on 110k miles and has had nothing changed on the rear brakes and is only just on its second set of front pads but original discs. And it was not a motorway mile cruncher, mostly local town driving plus it's an auto so should be heavier on brake wear...
