Not bad at all other than after 59,870 miles and 6 years in NE, the rotors had found a happy home and it took some coaxing to get them out.
I just came back from bedding them and the brakes feel very nice. The car is begging for a bleeding, but the fadish feel is gone.
As you can see from the photos (will post soon), one of the pads (passenger/non-sensor side) was down to the metal.
Of course, the sensor pad had the most material left so it never tripped.
A bit stinky as the top layer of the rotor got cleaned out, but overall very quick and clean job. No issues.
Very happy with the new brakes.
Oh, and I must have mistakenly selected and paid for 2 sensors while ending up not needing any. I guess I'll return them.
