The weather has been cold and crappy the past few weeks with a couple of snow days thrown in.
I postponed replacing the rear brakes hoping for a not-so-shitty day that I could get greasy and today was finally the day.
PowerStop Z17 Evolution Geomet coated rotors & ceramic pads had been ordered & delivered and I had picked up a 7mm Allen socket and an E-11 Torx socket to wind back the EPB mechanism.
Suffice it to say, this job was long overdue, and rather easy to boot.
Accessing, winding back the parking brake drive mechanism, compressing the brake piston and reassembling the EPB added less than 10 minutes a side.
Taking my time, this project took less than 2 hours, including going back and pulling one wheel again to refit the anti-rattle spring that flew off after I had put the car back on the ground.
And generally, since a post is worthless without pics, this is the better looking of the two rotors I replaced.

The brake parts were surprisingly roached after 2 years and 31,000 miles of pretty sedate mostly highway driving.
I’m especially (un)impressed by how glazed the OEM factory rotors got and the big areas of the friction surface that have just flaked off.
Especially considering that I drive this car like an old man.
I save the driving like an asshole for the Boxster S and the R56 Cooper.

I removed the pair of 5mm Allen bolts to access the drive mechanism for the EPB.
Then wound the shaft clockwise to permit retracting the brake piston, and then did the age old C-clamp trick to push the brake piston back into its bore and buttoned it up again.
I found there was no need to disconnect the EPB power.
There is plenty of power wire and brake line slack to separate the black plastic parking brake motor and the brake caliper to work inside.

Great write-up! I am amazed at the condition of the rotors after only 31,000. How much material was left on the pads? I do mostly highway and on my 2016 ext with 110,000 I am still on the original pads front and rear.

Mine looked the same. The rear rotors don't hold up to well to road salt.

Do you get road salt thrown down the way we do here?
It’s sickening how much damage that stuff does.
The inboard pads were near perfect, outboard ones not so much.
They were over half gone since they got the cheese grater treatment from running over those spots on the fronts of the rotors with the surface missing.

I do get lots of salt here in northern Illinois.
