If this is just to install the brakes they need to be shot. Took me 30 minutes to change all four. Not to mention I was using a floor jack and a rachet. A shop should be able to change all four in 15 minutes with a lift and a impact wrench.
Now if that includes the price of the pads I still believe its high but its not crazy. I bought the centric posi-quiet pads for $173 from a support vendor (
Zeckhausen Racing) and they are way better than stock (1/10 of the dust and the same braking power).
