And what if the brakes DON'T terminate and stay in one spot, and they DO keep going lower toward the floor?

What would be the issue, fix, and cost to fix?

not a common problem but doesn’t mean it can’t go bad. It happened in my car and I had all your symptoms and at last replacing master cylinder fixed it. I don’t think it’s something you can diagnose easily or will get an error code or engine light on these cars. I would check to make sure there is no leaks and pinches hoses first and then look into it. I’m sure there are ways to test it. The brakes on these cars are definitely good.

dewana421, can you elaborate a bit more on the change from oe to brembo....ie, road noise, change in distance, dust? what are all the benefits you noted?

I just got my car serviced and the dealer quoted me abt $900 for pads and rotors all around. WRONG

I have been considering both brembo and centric 4 wheel kits.

In the Rear video at 9;40-minute, you emphasized the alignment of holes while installing the new rotors.
Could you please explain which holes have to be aligned with what?

Even if I have not engaged the hand brake then I have to align the holes?
