I upgraded to A8 front rotors and tt carriers about 6 months ago. I changed my front brake pads, put on stainless steel lines all around, and changed the fluid (bled the brakes as well) about 2 months ago.

Just recently the car doesn't stop as good as it used to and I gotta push that pedal down pretty far sometimes to get it to start breaking good. I checked the pads all around are good. I also looked at the front caliper pistons and they are working good too. Im stumped on this one. Any ideas?

 

try bleeding your brakes again. also how do your rotors look? i remember when i put mine on, only part of the pad was actually touching the rotor so i had like a line where it wasn't touching.
