Hi all, was hoping for some advice. My 19 sti's brakes began squealing the other day. Over the next few days I began to hear a knocking noise that became more consistent. ( It sounded like it came from the engine bay I'm not sure now) I took a look and my pads are wedge shaped to the point where I have almost no pad left at the inside edge when the outside looks 100% . This is happening to both front wheels! My car only has 30000 km and had a service less than 10000 km ago where my brakes were inspected with no issues brought up. Does anyone know if this would be caliper pistons sticking? The bill is thousands if it's not under warranty 😒. I'm worried if the brakes are constantly dragging that I could be putting extra strain on clutch, drivetrain or engine, should I be concerned?
