Traction control and burning smell

[The Reaper]

A week ago I heard a kind of squealing and grinding noise from what appeared to be my rear brakes. I took it to a garage and had the discs and pads changed. The next day I noticed when driving around that there was a burning smell and when I quickly touched the discs I found them to be very hot and noticed scuff marks on the disc on the edge nearest the hub. I thought it was just part of the bedding in process and carried on as normally and it went away.
Well yesterday I was coming home and I heard the same squealing sound and grinding sound and have no idea why it's doing it.
I thought about my driving style and as it was driving quite hard that day and traction control was kicking in, I wondered if that had anything to do with it atall.
I am taking it back to the garage as it's obviously not right and wondered what could be causing these issues.

Your advice would be appreciated.

Thanks

Sounds as if you have a sticking caliper and the brake is binding. It's extremely common on the rear brakes of VAG cars as they useba single piston / slider arrangement. Sounds as if whoever changed the pads / discs didn't clean / lube the calipers to ensure they operated correctly.

Thanks for the advice. Hopefully he will clean it properly tomorrow

Come back and let us know how you get on.

Hand brake sticking?

The handbrake doesn't appear to be sticking and when I take the handbrake off the car seems to roll freely as I live on a hill.
I do notice though that when driving at around 20-30mph and I pull the handbrake really hard it will lock on and slide out to the left
