the rotor had clips on two of the studs. I removed the clips and getting the rotors off was easy. the reason I changed the rotor is I took it in for inspection and they found the caliper was leaking. they said the rotor was "too thin" and would have to be replaced also, the new rotor looks to be the same thickness as the old rotor. the dealer back in 2004 tried to get me on the too thin rotor on the front. I changed them about a year later and they were much thinner then the new ones. I cannot see paying some one to change the rotors at $300 when I can do it myself. the place I tried to get inspected wanted $415 to change the caliper, rotors, and pads on the rear. cost me $185 in parts(advance auto). big difference.
