Rear Brake Disc Wear

[itavaltalainen]

Highly doubt the brakes are worn - probably the usual sh!t that VW put on the rear brakes.

My GTD has done 18k miles now and they look f**ked. Spirited braking has not helped, they are grooved so badly. Complained to VW about it. Even my previous mk7 estate which had sh!t rear brakes (same PR code) was not as bad.

Just checked mine, at 11K miles, and the rear discs are a little scored, but the wear ridge on the edge of the disc is tiny, so not much wear. The fronts are nice and flat with an even smaller wear ridge, so the rears do seem to be wearing more than the fronts, although nothing like as bad as the OPs.
I'd put it down to the ebrake, auto-hold and cornering stability control.

I've just had my rear discs and pads changed at my 40000 service. They were badly scored and corroded but my front discs and pads are fine. In previous cars the fronts have always gone first. I have to admit to being lazy and using the ACC at every opportunity so I put it down to this but from previous replies maybe not. My wife's Polos front discs went after about 15000 miles and when I complained to VW dealer they said that living in the NE of Scotland it was probably being near the coast and the often gritted roads! Never got any further with that one.

I seem to remember someone saying once that actually less use was worse for disc brakes than more... ie they corrode more just sitting around for long periods than being driven some distance every day

Problem is the rear brakes on modern cars do very little braking, (just more for stability), so do tend to corrode more.

I'll be checking mine at lunchtime ahead of my first service in a few weeks (currently at 14k miles), and see what they look like.

The rears do nothing compared to the fronts, mine were looking terrible and after a few heavy braking sessions from 70 to stop they cleaned themselves up. With the electric handbrake you cant pull it on while driving to clean them up.

You can, just pull and hold. You might spin out though so be careful.
