I was recently recommended to replace the calipers, rotors and pads on my '99 Ford Expedition. The Power Stop team was great at helping me choose the right product (Ford had 12mm and 14mm studs on the hubs this year). These blocks arrived quickly and are very durable. The instructions are great (especially how to break in the pads). After removing the old rotors from the truck, installation was very easy. (Don't forget to apply anti-seize to the hubs!) I did a series of hard braking reps to heat up the pads and rotors and then let them cool down. The results are amazing! The truck stops quickly and silently! 5 stars around!
