See if the Auto Zone in your area has their brand of ceramic brake pads, people who have used then seem quite pleased and they come with a lifetime warranty.
Make sure to use plenty of sound deadening material on the new brake pads and do a full brake fluid bleed which will require 2 quarts of brake fluid.

 

The guy at the muffler shop said I should have the rear hub replaced at the same time as the rear break pads and rear rotors because the fluid leaking could cause damage to the newly installed parts. Is that true? Do I need to have the rear hub replaced at the same time as the pad and rotors?
