    hello
    i recently upgraded the front brakes on my 2015 gt automatic to the 6 piston brembos. i thought i would share my experience as i managed to do it fairly inexpensively. i noticed that people are selling their used brembos for far more than they can be had new. so i would like to include a parts list and where you can buy them from. you will need the following.
    1)brembo calipers from car id
    brcf 430 and brcf 431 140$ x 2
    2)the following from rockauto
    powerstop z23 $47
    raybestos 681954 rotor $65 x 2
    raybestos caliper hardware pack H18225A $12
    carlson banjo bolt +crush washers H94702 $1.82 x 2
    3)the following from tasca
    brake dust shields FR3Z 2K004-C and FR3Z 2K005-C $5 dollars each
    caliper bolts W716471-S439 $2 x 4

    total cost of the above is 491 dollars. you can count on $100 for shipping and tax. also, the calipers have a refundable $100 core deposit you get back when you return your old calipers.
    i used pentosin dot 4lv brake fluid. this is equivalent to the motorcraft dot 4lv that came with the car
    The brakes work great. slightly more grab than the originals. however, they were replacing 50,000 mile rotors/pads. very smooth and easy to modulate. silent as well. fit fine under the 19 inch painted dark silver wheel option.
    the 6 pistons have slightly less piston area than the 4 pistons. this is offset by the larger diameter rotor, however, in terms of torque.
    the stock master cylinder appears to be fine for this upgrade. im not sure what to say about the vorshlag experience.
    the braking bias does not seem to be affected. regardless, you can always alter bias by changing pads to higher/lower friction.
    the raybestos caliper hardware pack is $12 dollars for both sides. the oem one is 85 dollars per side.
    the raybestos 681954 is better than the 681954fzn as it is milled to a higher tolerance.
    the brake dust shields i listed look different and are much larger than the ones pictured with the ford performance brembo set. my understanding is that the new mustangs have this larger shield.
    install was fairly straightforward except for removing the old rotor. you will find it has seized in place. the videos show a guy tapping on it with a mallet a couple times and it is free. this is not the case. it will take ~100 hard blows per side with help from some liquid wrench. i also found that placing a jack under the disc and jacking the rotor up a bit helped to free it.
    you can reuse the banjo bolt but not the crush washers.
    the caliper bolts are microencapsulated and they recommend they be one use only
    the motive power bleeder works ok. it is quite messy and im not sure its better than a manual bleed. one thing i noticed is that if not enough pressure is placed in the chamber, a steady stream of very small bubbles emanates from the caliper that will not clear. my understanding is that this is air entrained from the threads of the bleed screw when the pressure in the system is too low.
    overall im very happy with the upgrade and i think any reasonably capable person could do the job successfully. the downside is that the kit adds 5lbs per side to your wheels.
    as far as jacking up the car, the easiest way is to place a jack in the middle of the car at the pinch weld. jack up the entire side and simultaneously place two jackstands under the jacking points. repeat for the other side.

    regards and good luck

    Good work!
    The difference in stopping power is amazing.
    However, you won't get a core back since you are not sending like for like.
    A 3# hammer does wonders on the old rotor. 3 whacks.

    And, I have a feeling you will be doing lots of mods: invest in some jacking rails.
    check Optimum Performance of you ever need brake parts.

    Thorn, is that the correct part number for the caliper hardware pack? Looking on RockAuto and the 816a shows for non-Brembo. Did you mean the 225a? Or am I missing something?

    Getting ready to tackle this myself. Excellent write up and really helpful with part numbers.

    Do you have to upgrade the master cylinder for base EcoBoost?

    Yes. Great write up! Wonder if the OP used the track app for braking with the stock setup. A before/after would be great!

    I got a loaded set of calipers and rotors last year for $400.

    Was from a member updating to a drag setup, wanted to get rid of them.
