Brakes Pulsating

[jcinmeforlife]

So, my front and rear brakes are perfect. I've even bled the brake lines to get the air out. However, when I'm comin' to a hard stop, I feel the brakes pulsating underneath the pedal. Last year I just replaced my front break pads AND had my rotors turned. The dealer suggested warped rotors. Any suggestions?

Welcome to AF.

It sounds like the rotors have excessive lateral runout (warped). If these were the original GM OE rotors the worse thing you can do is have them turned down versus replacement.

Get yourself a couple of good rotors, have them turned just to make sure they are true before you put them on, Install them, TORQUE THE LUG NUTS, and you should have smooth braking for a long time!!

So, indeed the rotors were warped. However, because I've been replacing my brakes/rotors every winter for the past three years, I decided that it was abnormal to do that and talked with a guy from Napa Auto parts about it. He suggested that my calipers were bad, especially if I noticed uneven wear on the brake pads, which I have. So, I replaced everything. Brake line, calipers, pads, and top of the line rotors. Cost me about $350 to do it, but I figured I saved a few hundred on labor. I'm finishing that junk up tonight and we'll see how it feels when I finally put my baby back together. Thank you for your help!
