23k and went metal to metal on rear brake pads/rotors
Grinding noise could only mean brake pad was seriously worn, but seemed so early, I was in self denial. Cursory inspection revealed uneven rotor wear on inside of rotor and a thin piece of pad. Researched what was going on. Adaptive cruise uses the electronic parking brake to slow down, automatic parking at stops uses the electronic parking brake, fast front dive stops has the computer kick in the electronic parking brake slightly early to level out the car. I drive 100 miles a day on a commute with 26k in one year. I drive the Washington DC metro area and the frequency of near misses and detected quick stops is a multi occurring event daily. I always use the adaptive cruise control and the automatic parking brake. I am replacing the rotors and pads myself. After three services and delivery experiences with my dealer which left me disappointed in the quality of work, I was not going to let them mess with my brakes. The brake hardware is impressive, my first Volvo. So, I will have to inspect and regularly change out rear pads more often. By the way dealer wanted $749 to do rotors and pads in rear. No service manuals of course, so it has been tough going. If anyone has experience with torque specs on brake caliper bracket bolts, let me know. I am doing 170 ft/lbs plus 60 degree turn. I had to ask Popeye to come take them off.
