Steps

1. Remove the wheel

   Pop the lug covers with a 19mm socket, pull the center cap, loosen the lugs with the car on the ground, then raise and support it and pull the wheel.

2. Remove the brake pads

   Remove the two 14mm caliper bolts, push the pistons back with a screwdriver, swing the caliper aside, then pry off the old pads.

3. Remove the rotor

   Remove the two 15mm bracket bolts, pull the bracket off, then pull the rotor off.

4. Remove the old hub

   Remove the four 15mm hub nuts, strike the hub with a hammer to loosen it, disconnect the ABS sensor if needed, then clean the mounting area with a wire brush.

5. Install the new hub

   Seat it while holding the backing plate, reconnect the ABS sensor, then torque the four 15mm nuts to about 65 ft-lb.

6. Reinstall the rotor

   Slide it on, refit the bracket, and torque its two 15mm bolts to about 50-55 ft-lb.

7. Reinstall the brake pads

   Grease the pad slides, seat the new pads, line up the caliper piston with the pad notch, refit the caliper, and torque its 14mm bolts to about 60-65 ft-lb.

8. Reinstall the wheel

   Torque the lug nuts to about 100 ft-lb in a crossing pattern, then refit the center cap and lug covers.

9. Test the brakes before driving normally

   Pump the pedal until firm, test stopping gently at 5 and 10 mph, then road test.
