A month or so ago i replaced brakes on car...keep in mind i have never taken a tire off car before. I had some intermittent help but did most myself. Which is possibly my problem. Got the z23 i think they are from rock auto. Back brakes i think are perfect but front i think are iffy. Noticed the other morning more give in brakes then i feel should be there, then noticed vibration today. Now, vibration and noise could have been there awhile, but i am usually rocking in my 76 mile trip into work. I looked after work and both front brakes seem weird, but i know nothing. The front rotors show wear for about 3/4" if that, and nothing else. The brake pad angle looks funny on both sides. What idiocracy have i done? Or is it i used wrong grease on shims? I will try to take pic tomorrow if it helps. Thanks in advance!
