Re: New brake pads?
How many miles are on your car? What type of driving conditions do you go through everyday? What is your driving style?
I used to work for a company that was trying to develop ceramic brake rotors and additives for ceramic brake pads.
Be VERY careful about what pads you switch to, especially on a vehicle this heavy. I spent time with companies like Performance Friction, Wellman Friction Products, and even Brembo. I learned that automotive manufacturers spend at LEAST $1MM validating the braking systems on a new vehicle prior to a launch. This is because, on average, the most common complaint on a new car is noise or vibration in the braking system.
After seeing tons of braking test data on a dyno I am now very weary about putting aftermarket brake pads on any vehicle I am driving. They don't spend $1MM testing their formulation on EVERY car. Odds are they pick a common vehicle (like a Ford Taurus or a Chevy Impala). The driving dynamics vary not only from vehicle to vehicle but within trim levels of a car depending on drivetrain, suspension, and even wheel configurations. No one single brake formulation compensates for this.
Think about it this way, if you go to Napa and buy their Gold series pads, do you really think they could design it to work perfectly on a Ford Taurus AND a 4,800 lb. SUV? An aggressive formulation for a 2.5 ton SUV would cause a Ford Taurus to screech to a halt. Also, if you put new brake pads on your car you should really have the rotors re-surfaced so the new pads will bed in on a clean surface. Your existing setup has built up a film layer on your rotors and it would dramatically impact how your new pads break-in and wear.
Millions of people but average brake pads on their vehicles every year. And for most people that is fine. So ultimately, do what you think is best for your car. But after seeing test data of one brake pad formulation on multiple vehicles I was completely turned off from aftermarket brake pads. If this was a light vehicle, you probably would never know the difference. But on a vehicle that is this heavy, be careful.
I vote for sticking with the OE setup. Car and Driver and Motor Trend both liked the consistency of this brake pad in their tests. They noted stable, consistent performance over multiple hard stops. Just my two cents...
