I am going to change out my rotors and was wondering if I use a different pad in the front and leave the stock pads in the rear, will I have any problems? Is it ok to do this or should I go ahead and change out all 4 sides?
You shouldn't have any problems. There are guys here who run ceramics up front w/ stockers in the rear to min. dusting. Since you're already there while replacing the rotors, why not replace all 4? :guiness:
It is fine as long as the pads that you are changing to on the front have a higher co-Friction than the pads on the rear. If there is a higher Coefficient of friction on the rear, brake bias will be shifted to the rear which may present a unstable situation. http://www.stoptech.com/technical/balancedchart.htm
