Brakes

05 dodge neon sxt 4 cylinder auto 50000. The front passenger out board pad wore at about 50% faster than the inside pad. I just replaced the front pads and rotors, and rear drums and shoes. All with wagner thermoquiet products. I am getting a pulsating or vibration in the brake pedal when partially depressed. The guide bolts are not rusted the sleeves are not rusted, and the boots had grease and where regreased. There are no other signs of problems with brake system. I do not want to have the same pad problem as before. I can not find a reason for the problem. I consulted the factory manual and a mechanic. Both seemed to point to the guide bolts or sleeves. Any help would be appreiciated.
