The CX-9 became my daily driver last December. I love the car, and for an SUV, it is actually not that bad, considering I hate SUV's and I hate automatics. Anyway, to the point. Like everyone else here, the front brakes were warped and pretty much junk. I purchased Power Slot Rotors and Hawk HPS pads as my set up. I went to my mechanic and had him install them along with bleeding the brakes and adding SuperBlue brake fluid.
While no more vibration exists at higway speeds, Here is the problem.
The brake pedal requires way too much effort now. In order to properly bed in the pads to the rotors, I did some 4 slowdowns from 80 to 40 with a good amount of pedal pressure. I went and filled up with fuel and the rear brakes (stock) were hot as hell, the fronts were actually cooler and there was a good amount of brake dust in the front as well. Something still did not feel right about the car. I took it all the way up to 60mph and tried to do an emergency complete stop. After nearly putting tons of force onto the pedal, they lock up and ABS activated. This is a problem. All 9's come equiped with "Brake Assist" which, in emergency situations, provides additional braking support without extra effort from the driver. My 2002 BMW 330ci had this, it is a very cool feature as it gives you maximum braking instantly!
Superblue fluid is DOT 4 and (I believe) all it does is have a higher boiling point, so I highly doubt that's the problem, but my mechanic stated that could be the problem. I'm thinking there is air in the brake lines or that the brake pads are not good? Can anyone help me with this? My mechanic test drove it today and he had no idea about brake assist and did not understand what I meant by the amount of pressure the brake pedal needed. He told me to just continue driving it and it will get better. He also added that I was just wasting my money, but whatever, I have used that set-up before and it has been very good to me, that's why I went with it.
Any help would be appreciated.
