OK so this weekend I tackled my brakes. Here's what the rusty rotors look like behind my wheels:
Pic of the wheel removed. If you've never had to remove your wheels, or it's been a while since you have, the wheel is likely frozen to the hub. You'll need a rubber mallet to help knock it loose:
Pic of the caliper removed. You'll need a 15mm socket and an 18mm open end wrench to remove the caliper mounting bolts:
Pic of the caliper mounting bracket removed. The bracket is held on (tightly) with two 21mm bolts. You will need a breaker bar or some other force multiplier to persuade these bolts to let go:
Most likely your stock rotor is rusted and frozen to the hub like mine were. Some penetrating lubricant and a rubber mallet really come in handy freeing the rotor from the hub:
A comparison of my front stock rotor and the new DBA rotors (with the centers painted black by me):
New rotor mounted on the hub and temporarily held in place by stock lugnuts. I cleaned up the hub surface with a wire brush and applied some anti-seize so that the rotor does not seize to the hub:
Wheel mounted back on:
Rear wheel removed. Caliper mounting bolts are 15mm, and caliper bracket bolts on the rear are 19mm:
