Rear brake disc corrosion uneven wear

[aldouk]

Is it pretty standard that the rear brake discs aren’t as shiny and more corroded as though the pads have uneven wear. 
 

This is what mine look like after a good run out today, plenty of downhill braking too along the coastal roads.

How old is the car

Sadly that is what you can get with a Skoda regardless of model. 

About the cheapest consumables that VW group can source.   It is hard to find any aftermarket replacements that are worse no matter how cheap you pay.

What were they like before you went out?

 

Downhill braking or proper braking?

 

Many people sit on the brakes going down hill and end up just polishing and heating, not break-in effectively.

On the plus side the disc hubs seem to have stayed remarkably corrosion free !!

my 2016 car had very badly scored discs and pads (280 combi) with less than 20k miles on them.

 

its commonly reported for the golf R made around then as well, so I changed the discs and pads for new ones a few months ago.

 

its an updated part number, and reports from other forums (and from my own observations so far) is that they are not showing any scoring (yet)

Car is 19 months with 14k. Proper braking too, they aren’t cooked and that is how they are all the time recently. I thought the long journey would give them a clean up lol. 
 

Yes I don’t use any acid based cleaning stuff so the hubs have stayed reasonably tidy

Nor do I but my hubs look like they sunk with the Titanic.

I replaced mine as they looked really horrible... I also put on Ceramic pads from ATE. What a difference!

I’m getting MTEC black discs

Really it should be a mandatory recall by skoda to remove the discs and replace with ones of improved quality.

That new pad wear looks suspicious too. Do I see grooves appearing in the disk? Are your roads covered in salt/grit from Winter?

These ATE rotors are made this way, they're not simply straight metal. And no.

OK now I zoomed your image, I can see its machining. 

 

Never seen it done in concentric rings before. I suppose it will help the pads to bed (yet) in and (initially) give some stopping power.
