I drive 15 miles on the freeway to work, then I drive 10+/- miles each day in the city, then take the freeway home again. On the ramps and accelerating to freeway speeds, braking quickly for the "J-turns" we have here in the stop-and-go city, it all used to be bad for my brakes. But not with these. They stay cool, they are very quiet and efficient. THEY ARE AMAZING! I installed them on my 2008 Scion xB but then sold it. So now I have to order these for my 2015 Scion xB. What a great discovery…
