Still having trouble. My setup is brembo rotors with hawk pads. My problem: the pads rub against the rotors. I did some measurements. The brembo and stock rotors are the same thickness. The hawk pads are thicker the the stock pads. I put the stock pads on, and noticed the rubbing went away a bit, but sometimes it still would. I also pressed on the brake pedal, and tired to spin the rotors again to check from rubbing, and noticed that the rotor would not turn very much, as if the brakes were engaged.
My ideas/questions:
1) how can i set up the pads so they do not rub? i have done brake pads before on other cars, and this car just leaves me scratching my head.
2)Is the caliper piston seized/ seizing? As in, I think the caliper piston is not returning into the caliper, which cause the heavy rubbing after pressing the brake pedal. Keep in mind, the car is off. I am able to press the piston back into the caliper using a c clamp.
3) How will i make my hawk pads work? I have no clue how many miles are on the stock pads, so i do not know if they are newish, or say 40% gone.
4) is their supposed to be some rubbing on the rotor?

Re: front brake problem
Did you lube the sliders on the caliper? I experienced the same thing when i forgot to lube them when I did my brakes. Lubed the sliders and she was good to go.

That is possible but is no indication of a 'good' caliper & piston.
Supposed to be, no in theory when the piston retracts by it self, but in practice with the pad taper & disk run out & anti-rattle shim s.h.i.t, they'll rub - slight sound but no drag that would amount to anything.
