I have a 2000 gt auto with a 100k on it, I have replaced my breaks with the best pads & drilled/slotted all the way around.. and my breaks work but it seems they should be a lot better than they are.. (any advice) there's no air in the lines, it was all done the beginning of this summer so my car should stop on a dime & it's more like I have stock break. Is there something I else I should have done?
