Question:

Is it okay if I run with ceramic brakes on my front end & non-ceramic brakes on my rear?

Is it okay if I run with ceramic brakes on my front end & non-ceramic brakes on my rear?

Answer:

Ceramic pads were designed for very hi heat applications, like road racers and rally cars. The good news is they can take the heat, but the bad news is they are hard on your rotors. So expect your brake hard parts, rotors drums, to wear faster then they would with a softer pad/shoe. The rear brakes do much less work, but hard/ceramic pads/shoes back there will accelerate wear also. Either rear pad will work; Hawk makes good stuff.
i would go with whatever is factory material for your car as ceramic pads are harder and yes last longer but if factory style rotors are not meant for ceramic pads then your going to wear out your rotors a lot faster also ceramic pads are stiffer and do not work as well cold(not really a big difference on cold braking) i believe an 07 should have ceramic as factory material as most do now my 06 sentra uses ceramic as factory and my 00 celica did as well
It would be OK to have different pads on the front and year but the ceramic pads would be the better choice unless you intend to be doing a lot of hard stopping from high speed. Ceramic pads are quieter, produce less dust which might damage the finish on the car and wheels, and do not wear away the rotors. The other pads are semi-metallic which might give a bit more stopping power and will last longer but they will wear the rotors away faster and produce more noise. I doubt you would get much benefit from semimetallic brakes in the rear because the rear brakes usually less than 30% of the brake force. There are four general types of brake pads for cars: Ceramic: These are composed of ceramic fibers, nonferrous filler materials, bonding agents, and possibly small amounts of metal. Lighter in color and more expensive than other brake pads, ceramic pads are cleaner and quieter, and offer excellent braking characteristics without wearing down the rotors. Semimetallic: This formula, containing about 30 to 65 percent metal, typically includes chopped steel wool or wire, iron powder, copper or graphite mixed with inorganic fillers, and friction modifiers that bond all the ingredients together. These pads are more durable and have excellent heat transfer, but also wear down rotors faster, can be noisy, and may not perform optimally at low temperatures. Nonasbestos organic: Sometimes listed as organic or NAO, this type of pad is made from fibers, such as glass, rubber, carbon, and Kevlar, with filler materials and high-temperature resins. These pads are softer and create less noise, but they wear faster and create more dust. Low-metallic NAO: These are made from an organic formula mixed with small amounts (10 to 30 percent) of copper or steel to help with heat transfer and provide better braking. With the added metal, there is more brake dust and they may be slightly noisier.
