[Shotimes] Front Rotor Warping

[sho2go]

I fully believe this message, and method of wearing in brakes.  2 months ago
I put a set of chinese AIMCO rotors, and PFCM pads on the front, and
original rotors/NAPA  pads on the rear.  Went out and really smoked them;
the fronts were hot as hell while the rears were only warm.  Changed the
rears to Ford oem pads, now the balance appears better as fronts and rears
heat at equal rates (more or less; didn't measure temp.)  This is after the
brakes warm up; the PFCM pads don't grab as well when cold.  Don't forget
guys, the brakes don't stop your car.  They only stop the wheels.  The tires
do the actual stopping.
