I changed the pads on the Audi a few months ago. Last month I noticed the offside brake was only wearing on half the disk on the outside. I took the discs and pads off and sanded them both down. Copper slipped the sliders and everything back up but now its doing exactly the same thing.
Could it be down to using cheap pads or bad discs? I've heard it could be the sliders but they look fine to me?
Also the brakes just feel all around terrible. Other people who have drove the car said the same lol
