To maintain your disc brakes, you need to make sure that your calipers, brake rotors, and brake pads are in good condition. If you've heard screeching sounds coming from your brakes, then it's likely your brake pads are worn out. You can replace them to return your Mustang to like-new performance, or you can upgrade them. Better brake pads are resistant to brake fade and can perform in high-speed situations without losing their stopping power.
Your rotors are also able to be replaced or upgraded for additional performance benefits. Having larger rotors looks great, but it also helps your brakes to stay cool, and gives your brakes a larger surface to grip.
If you want the most stopping power possible, then you're going to be looking at a big brake kit. This combines performance pads, rotors, and calipers along with the hardware you'll need to install them, into a convenient kit. You'll have everything you need to stop faster and be more confident in your Mustang's safety.
