I cannot figure what is going wrong with my front brakes. I have Brembo 4 piston brakes with Brembo stock 14" rotors. They pulse all the time. I actually have two sets of rotors. When I turn them, they show very little if any runout. I have tried three different style pads... stock Brembo, Hawk ceramic, and green stuff. When I change the brakes, I am super good to make sure every surface from the hub to the wheel are cleaned with a wire brush and that they are flat. Last Friday I installed the freshly turned rotors. They were dial indicated and showed almost zero run out. I put on seasoned pads from Hawk that had one or two track runs. They also had been properly seasoned when they were new. I flushed the brake fluid and put DOT 4 fluid in. The calipers were torqued to 75 ft lbs and lock tite was used on the threads. All rotors were cleaned with solvent and then soap and water.

The first drive was full of shutter at first. Within a few miles they began to smooth out. The car sat all weekend. This morning, as I drove to work, they were pulsating even with light stops. High speed or low speed same thing.

I do not want to go buy expensive rotors and pads until I resolve this issue.

The wheels are torqued to 105 ft lbs. The hubs seem tight. At least when I jack the car and wiggle the wheel, it does not move like a bad bearing.

The last time I did this same procedure, it took 3 days for the pulsating to show up.

What am I doing wrong??
