Review & Installation Video

Review & Install Video

Hey guys, Stephanie with here with an overview of the Ford Performance six-piston front brake upgrade kit for the 2015 and newer S550 Mustang. In this video we're going to go over a few things with this kit. We're going to talk about who this is going to be an upgrade for, the components of this kit, and the install as well. I'll go over the install in more detail later, but I'll tell you now that the install for this is going to be a two out of three wrenches on the scale. It's not too difficult, but it's not for the first-time wrencher either. The Ford Performance six-piston front brake upgrade kit is going to be something that you should check out if you didn't opt for the Performance Pack model when you purchased your S550 but you want the benefit of that extra stopping power that the Performance Pack brakes offer. If you didn't pick up a Performance Pack model, you ended up with a four-piston brake setup. This kit and the Performance Pack cars offer a six-piston caliper and slightly larger rotors, and this doesn't sound like much when I say it but it does make a significant difference in stopping performance. This kit is going to appeal to a couple of different types of owners. It's obviously going to appeal to those S550 owners who track their cars, but it's even going to appeal to those who don't. Big brake kits are an excellent upgrade if your car sees mostly street time, and this kit is perfect for those of you that are looking for a huge upgrade in stopping power over your base factory setup. If you're looking for a solid all-inclusive upgrade from Ford Racing and Brembo, this is the ticket. As far as brake kits and brake upgrades go, bigger does tend to be better. Braking performance depends on surface area, and by this I mean how much surface area the brake pads have to bite into. Larger discs and larger pads have more surface area and therefore allow for shorter, faster stops simply because of the bite that the brakes will have. On top of that, increased surface area means better heat dispersal, and with brakes you want as little heat as possible if you want highly effective stopping power. Because this kit is actually original equipment for the Performance Pack cars, this is a bolt on front brake kit that's going to come complete with all of the items that you need for the upgrade. The kit offers these big boy six-piston calipers, 15-inch Brembo front rotors, front brake pads and dust shields, and install hardware as well. Like I mentioned earlier, six-piston calipers are going to be an upgrade over the four-piston calipers. That's going to be another two pistons for each side pushing that pad and creating a greater wider clamping force. The upgrade in pistons does mean a tip in brake bias though, so that's just something that you have to keep in mind. These front calipers are going to require a greater amount of fluid as well. Moving on to the brake pads, the pads are an important piece of the puzzle here. They are a component that's going to be directly in contact with the friction surface, so you want to make sure that you're getting the right brake pads for your application and for your rotors. These are 15-inch iron rotors which are vented. Venting the rotors is a way to cool the rotors since the friction between the pads and the rotors is going to create heat and gases and dust. The vents give a place for all of this to escape to, which then means more contact surface area for the brake pad and that means better braking and less brake fade. Since these rotors and pads are already kitted for you and you know that they come factory in the Performance Pack cars, you know that you're getting components that are going to work well together. Ford has taken the guesswork out of the equation there. These are going to be your main components of this kit. The caliper and the rotor combo will give a ton of surface area for more stopping power and better heat dissipation. On average, the front brakes are handling roughly 75% of the braking duties, so when you make this kind of upgrade, the difference should be immediately noticeable. My one nitpick with this kit though would be that it doesn't include stainless steel brake lines. You'll be getting the stock factory lines, which isn't the end of the world, but I would've liked to have seen new stainless steel lines in place of the factory replacements. But in all honesty, this is a factory upgrade kit, so I'm not really all that surprised that it doesn't come with aftermarket lines. On the topic of price, you're looking at a $1300 price tag for this kit. This may sound a touch expensive, but in the world of big brake upgrade kits this is actually very budget friendly. You are upgrading the factory components here but this is still a big upgrade for all the non-Performance Pack Mustangs out there. Not to mention, if you're interested in any other kit, you're looking at spending more than double the price for those. Installing a kit like this is definitely not for the first-time wrencher out there. To give a general overview of the install, you're first going to want to double check that you won't have any clearance issues with your wheels. These brakes require that you have 19-inch wheels or larger or else you're going to be looking at clearance problems, so just keep that in mind. I say that this isn't for the first-time wrencher because you will need to bleed the brakes properly in addition to physically installing the kit, so therefore I'll call it a two out of three wrenches on the difficulty meter. I'm not going to give it a full three out of three because it's really not rocket science, but if you've never bled brakes before, you might want to get some help on this one because brakes are kind of important. Either way, figure a few hours in the garage, a decent socket and wrench set along with the necessary bleeding tools, and don't forget fresh brake fluid to finish the job. Wrapping things up here with the Ford Performance six-piston front brake upgrade kit, this is a serious braking upgrade for the base model S550s that cannot currently be beat in price. This kit'll upgrade you to six-piston calipers and 15-inch vented rotors. As always, I suggest you check it out more online for yourself and for all things Mustang keep it right here at

      I see one previous question regarding whether the upgrade kit will adversely affect the ABS and Traction Control systems on a base GT (mine is a 2016 with manual transmission). The answer provided was a "guess" that the ABS would compensate. Isn't there a more definitive answer to this question? 1 answer

          Great value on a Brembo Brake

          The brakes fit well, I just wish ford performance made a rear brake to compliment these.

          6 piston upgrade

          I installed these at a shop to replace the original brakes in my 2016 California Special. What a differece. I also purchased stainless steel lines and performance brake fluid. The car feels just like stock at low speeds, but you can feel the improvement the faster you go. Really secure, specially if you have other suspension/bigger tire kit.

          Strong Brakes

          Since Having a Roush phase 2 supercharger installed on my 2017 Mustang GT I decided it best to step up to stronger brakes. All that was needed to make the change was included in the kit. The installation was straight forward and anyone who has ever done any brake work should have no problem. I would advise checking out youtube to get guidance help on the installation. I am really quite pleased with the product and American Muscle's price was about $200 less than others online.

          Premimum GT Brembo brake upgrade

          Best bag for the buck out there. Direct bolt on with no issues - perfect fitment. No other upgrades required to make this kit work. My install time was roughly 2 hours. No installation instructions were included, but no big deal. Some sources will tell you that there is a specific order in bleeding the brakes so do your homework. Otherwise, the stopping power is incredible.

          True Bolt On Replacement Kit

          Installed on a 2017 Mustang GT Automatic (non-PP) with no issues. We painted the calipers Grabber Blue to match the car. Ford Performance verified no other modifications than what was in the kit are needed. That is, no Brake Booster, or modification to ABS needed.

          Looks and perform like a race car

          I have an base model ecoboost Mustang after doing some research I decide to change the wheels because this massive brake system is going to need some room so I have decide to install 20" mmd 551c wheels which looks awesome and have enough room for the brakes, knowing that 19" could clear I went for 20" to be sure, now time to install the new brakes, when opening the boxes the kit came with 2 dust shields, 4 bolts, 2 massive rotors, 2 brake hoses, 4 cooper washers, 2 monster brake calipers with brake pats installed, for the installation it took me about 2.5 hours being the most difficult part draining the brake fluid, you have to go inside , outside , then inside until no bubbles came from the hose , I haven't do any modification in order to install this kit and it will fit any base ecoboost Mustang with proper wheel clearance :D
