2015 is 250. Should I just go to the dealer and do oem brakes and rotors or should I get something else?​

If I go with after market for front and oem for the rear is that a problem since my rears are still good?
I just changed my tires and the shop said my front brakes are 3 out of 10 done but my rears are 8 out of 10..how is that possible?

If I bleed the brakes as well, can I just so the fronts and not the rear?

 

Should I just go to the dealer and do oem brakes and rotors or should I get something else?​ It's really your preference...you can't go wrong with OEM, however, there are quality aftermarket parts that perform as well or better for the same or a lower cost.
If I go with after market for front and oem for the rear is that a problem since my rears are still good? That will be fine, you can use a mix of OEM and aftermarket.
I just changed my tires and the shop said my front brakes are 3 out of 10 done but my rears are 8 out of 10..how is that possible? As most of the braking is done by the front brakes (approx. 65%), they will tend to wear faster. Also driving style plays a factor.
If I bleed the brakes as well, can I just so the fronts and not the rear? If you mean flush the brake fluid, then you might as well do the front and rear, as if you only do the front, the remaining old fluid will eventually mix throughout the system. If you were replacing one caliper, for example, then I would say yes to just bleed the one caliper, the premise being you are only trying to get air out, not change the fluid.

 

Should I change the brake fluid when I am changing the front rotor and pads? My car is at 71,000 miles now and I don't know if the fluid was ever changed..
And how much do I need?

​​​​​​Will the Akebono Performance pads ASP908B fit a 2015 f sport rwd sedan? Tirerack says its for the convertible?
Or should I go with the ACT1178A Proact?

I am also looking at the centec PLAIN 120 SERIES ROTORS, but again it says its for the convertible. Will they fit a sedan? thanks

 

In regards to the brake fluid:

I recently bled my brake fluid and found that 1 Liter of brake fluid was enough for the entire system. I bought three 500mL bottles of brake fluid just to be safe, but didn't use 1 of the bottles. I'd recommend flushing the rear and front because it is an easy enough procedure albeit a little time consuming. Specifically, the back right rear bleed took the longest, while the front 2 were relatively quick.

Order I would do it if I were you: 1) Bleed back right, 2) Bleed back left, 3) change brake parts of front right, 4) Bleed front right, 5) Change brake parts of front left, 6) Bleed front left. Someone correct me if I'm wrong.

I know you didn't ask for pricing, but thought I'd share the price quotes I received from a dealership (which I didn't follow through with):
Dealership quote for new front pads + turn rotors + tax = $357. Dealership quote for New front pads + New rotors + Tax: ~$600 something.
