      Video Review & Installation

      Hey, guys. It's Sara with And today, we have a review and install of the Power Stop Z23 Evolution Sport Brake Rotor and Pad Kit for the Front and the Rear, fitting your '15 and newer V6 or standard brake-equipped EcoBoost Mustangs. This is perfect for the Mustang owner who's looking to replace their pads and rotors all around and wants an upgraded option over an OE replacement. This complete brake pad and rotor kit for the front and rear was designed for daily driver or street use and improves performance, as well as minimizing fade, thanks to the drilled and slotted rotor, and ceramic compound pads. The cross-drilled and slotted rotors keep your brakes cool and clean while the ceramic compound pads give you that extra bite, giving you all in all more braking performance with minimal dust and noise.So Power Stop has lots of options for your Mustang from OE replacements, all the way up to track day options. This Z23 kit falls right about in the middle, giving you more raking performance over an OE replacement, but not quite as much as a track day option would. This is because the option for the brake pad in the track day setup is much harder of a compound than what we have here. But the trade-off for that is there's gonna be quite a bit more dust and noise.So as far as price goes, this kit comes in right around $350, which is gonna run you a bit more than an OE replacement would. And for your money, you're getting the upgraded components that come in this kit that will get you more stopping power. I'm giving this install a two out of three wrenches on the difficulty meter. It features a direct bolt up install the same as any brake job and can be done within two hours. So with that said, let's jump into our install.For this install, you will need ratchets or an impact gun, an 18-millimeter ratcheting wrench, 15 and 14-millimeter sockets, as well as a small extension, flathead screwdriver, caliper hanger tool, caliper tool, and the tool to twist in the rear caliper. All right, so the first step in our install is with the front wheel off we're gonna use a 14-millimeter socket and remove the caliper off of the bracket. Using your 14-millimeter socket, remove the two bolts at the back of the caliper. Wiggle your caliper off, grab a hanger tool or you can use a bungee cord if you don't have one. As long as the tension is off of the caliper itself, you should be good to go.Next up, grab a 15-millimeter socket and remove the two bolts holding on your caliper bracket. Make sure to keep a hand on your bracket after you get the second bolt out. Grab your caliper bracket and remove it off the Mustang. All right, so at this point, our rotor is ready to come off and as you can see, it's fairly loose. If for some reason your rotor is not, you can hit it right back where the caliper was bolted up with a rubber mallet on the backside and it should loosen itself up. Once it is, go ahead and wiggle it off.All right, now that we have our factory pads and rotors uninstalled from the Mustang, we can check them out side by side with our Power Stop kit. Now the most visible difference here is the drilling and slotting of the rotors, as I said before, gonna help keep your brakes cool and clean. A little bit less noticeable is the ceramic compound of the pads. It's gonna give you more pad bite, better performance than an OE replacement would. In addition, they also give you these clips to hold the brake pads in the caliper bracket, which are nice to have to replace your worn out stock ones. So, with that said, let's finish up our install.All right, so now that we have the caliper bracket off of the car, we can remove the brake pads. Now you can do this on car but it's a little easier to show you guys. We're also gonna be transferring over these clips at the same time. So just grab the brake pad, slide it out. Also gonna pop these clips off as well. If doing it by hand isn't cutting it, you can use a flathead and just pry it gently. All right, now, we can install the new clips. Now you can reuse your old ones if you like. But since they've included these new ones, they're definitely gonna function a lot better than the aging ones on the car. Just go ahead and press them into place. With the large tab facing up, make sure they're aligned perfectly with the bracket.Grab our new brake pad and we're using the one with the feeler towards the back here, same as OEM. Now it is nice these feelers can be removed and moved around. Go ahead and slide them in place. And I will say that if you're installing this, you do wanna put some grease in these sliders here so the brake pad can move back and forth easily. And putting a little bit on the back of each pad doesn't hurt as well and will cut down on noise. Since this is just for demonstration, we're gonna skip that step. All right, and now we can finish up our install.All right, so now we can get the rotor installed on the Mustang. You do wanna spray the front as well as the back of this rotor with some Brakleen just to clean off the oils that come on it from the factory. The other important thing is these are directional because they're drilled and slotted so you wanna make sure you're grabbing the one for the right side. We're working on the driver side so we have the front driver side here. Another tip is I like to throw a lug nut on here just to hold the rotor in place while we get the bracket installed, just for some added safety.All right, now we can install our bracket with our brake pads over top of the rotor. Line it up to the factory mounting points and reinstall your factory hardware. Grab your 15-millimeter socket and tighten it down. All right, so at this point, we need to push in the pistons on the caliper to accommodate the larger brake pads. Now, we're using a caliper tool here. If you don't have one, a C-clamp will work in a pinch, but this guy makes it a whole lot easier. So if you can get your hands on one, I highly suggest it. Now, we're trying to push in these pistons about as close as we can get to flush with the caliper so that they can clear the fat brand new pads. Now, we are using a tool that's for a single-piston caliper. I realized that if you push one side in, the other side may come back out. That's because this large piece here sort of prevents the other tool we have from working. So long as you're doing this carefully and keeping them even, you should be fine.All right, now you can slide your caliper over top of the brake pads, line it up with the sliders, and reinstall your hardware. This is a good time as well to just take a second look at your sliders at the caliper itself. Make sure everything is in working order because it might be a good time to replace some stuff while you have everything apart. Once you've installed these, grab your 14-millimeter socket and tighten them down.All right, so the first step for the uninstall for the rear is to grab a 14-millimeter socket and remove both the bolts at the back of the caliper. All right, with our 14-millimeter socket, remove both the bolts holding on the caliper. Then you can wiggle the caliper loose and remove it off of the bracket and pads. You wanna grab a caliper hanger tool and hang it out of the way, careful not to put tension on either the brake line or the e-brake cable. All right, four of these caliper bracket bolts, they're kind of in an area with not a lot of space, so we're using an 18-millimeter ratcheting wrench you can use and a socket and a ratchet as well. But this one is pretty long, we can get a good amount of torque on it to be able to crack it loose. So we're gonna leave that one in a tiny little bit so we can pull out the bottom one and we're not fighting with the bracket trying to release. All right, remove the bolts and then remove the bracket off of your car. All right, so the rotor is pretty loose back here. If for some reason yours is not, you can tap on back right in the area where the caliper came off with a rubber mallet and then wiggle it loose, and remove it off the car.All right, so at this point, we're gonna remove the brake pads. Just go ahead and slide them out of the metal clips. And then remove the metal clips either by hand or you can use a flathead screwdriver, and just gently work them off. Depending on how much build-up there is, you may want to take a wire brush to this area right in here before we install the new ones. Grab your new clips, line them up, and press them over top of these tabs here. Make sure they're nice and even over both tabs. The larger portion should be facing up and there are clips on the back and front of each of these where they join to the tabs on your bracket. Once your clips are in place, you can install the brake pads. Now the one with the feeler goes towards the back. So go ahead and slide that one in. Now we're doing this demonstration so we're gonna skip this step. But you would want to grease these openings in here. And it doesn't hurt to put a little grease on the back of each brake pad, right where it contacts the piston or the front of the caliper, just to cut down on noise. You just wanna make sure that the pads themselves can freely slide back and forth so they function properly. All right, with the pads in place, we can finish up our install.All right, so now we can install the rotor on your car. Before you do this, you do wanna spray the backside as well as the front side, just around the edge with some Brakleen. That will just remove the oils from the factory off of the rotor, just making sure it's nice and clean and it can function properly on your car. After that, grab a lug nut, throw it on one of the studs here, that should keep the rotor in place while you finish the install, just for some added safety.All right, at this point, you can install the caliper bracket with the brake pads in it over top of your rotor. Grab your factory hardware and thread it into the back of the bracket. Grab your 18-millimeter socket or 18-millimeter ratcheting wrench and tighten these down. All right, so at this point, we have to compress the piston in the caliper so that it fits over our new brake pads. This is a little bit different from the front section. Instead of pushing it in with the tool, we need this special block tool and just your regular ratchet and we have to twist this in. So make sure that you're using the proper tool for this rear because it's not the same as the front. Make sure you get a good grip on the piston and then we're tightening it in, so we're twisting it clockwise to force it back into our caliper. Just take your time, make sure you got a good grip with the tool you're twisting the piston in. We're gonna try to get it in as far as it will go so it's nice and flush to the caliper and it will clear the brake pads.All right, once it's twisted all the way in, slide it back over the pads over top of the sliders, then we'll put in our bolts. Grab your factory hardware and reinstall it into the back of the sliders. Now, if I haven't mentioned before, this is also a good time to check the sliders here and the function of your caliper. Make sure that nothing else needs to be replaced while you have everything apart. Your boots are ripped, or a slider's stuck, now's a great time to swap that out. Make sure you have a properly functioning brake system. With your bolts installed, go ahead and grab your 14-millimeter socket and tighten them down.All right, so once you're finished with the front and the rear, repeat that process on the other side. When you're all finished, make sure that you're pumping your brakes to seat the caliper to the brake pads and make sure that you have a nice stiff brake pedal before you drive anywhere. But that is going to do it for the review and install of this brake pad and rotor kit. And remember, for all things Mustang, keep it at

By casting these Z23 Evolution Sport Rotors out of iron using superior G3000-grade casting and OE tolerances, Power Stop ensures a perfect fit and incredible durability, meaning you'll see a ton of use out of them.
