Just wanted share something that made a huge difference in my Grand Prix's breaking ability with 103K miles.
I constantly had warping rotors and the brakes just never felt "right". After reading about a lot of peoples thoughts I decided to do the following;
2 new wheel bearings (Timkin) to get rid of the sloppy factory bearings.
Goodridge braided steel brake hoses
Brembo OEM Front replacement rotors
Wagner rear rotors
EBC Red pads front and rear
What a difference!! The pedal feels so much firmer and the bite is awesome.
Hope this helps anyone looking to really improve their brakes without breaking the bank.
