Welcome to the CorkSport 13” Big Brake Kit for the 2014-2018 Mazda 3, 2014+ Mazda 6 and 2013 - 2025 CX-5. We’ve stepped up the performance with this new 13” BBK for the 3rd GEN platform. Comparing to our current 325mm caliper and rotor kit, this is a great performance increase due to the larger diameter and thicker rotor and much larger calipers which can apply a higher clamping force.
The brake system has to deal with many factors to achieve a high level braking performance, whether it is clamping force, weight or heat. Each of these factors has been taken into considered with the CorkSport BBK to achieve elevated braking performance in your Mazda. This is accomplished through a combination of improvements including increased rotor diameter, a larger piston surface area and braided stainless steel brake lines. Read more below about the details into each of these enhancements over the OEM brake system.
One of the most important upgrades included in the CS BBK is the rotor size and design. Starting with the OEM rotor size of 11.02”(280mm) or 11.61”(295mm) for the S trim level, the CS rotors are 13”(330mm) which equates to an increase in size between 1.39”-1.98”(35-50mm). The CS rotors are not only bigger in diameter they are also thicker, going from 0.98”(25mm) to 1.10”(28mm). Both of these changes add material to the rotor so that is can better distribute and dissipate heat so the brakes can go longer without overheating. The increase in diameter also provides another advantage by being able to apply more torque with the same amount of force being applied to the brake. The CorkSport rotors also feature a two-piece design with an aluminum inner hat to reduce weight and help cooling and an outer ring that can be replaced separately to save money when needing a replacement. The outer ring also features vanes on the inside that aid in cooling by pulling in cool air when the rotor is spinning. The last feature of the CS rotors is that they are slotted to help remove brake dust and gases that could negatively affect braking.
The calipers in the CorkSport 3rd GEN Big Brake Kit are 4-piston units machined from forged aluminum. The 4 piston design offers a significant advantage over the OEM calipers which only have a single piston. While each piston by itself is smaller than the single OEM piston, the overall piston area is greater. This leads to an increase in braking force from the same amount of braking pressure. Plus, having pistons on both sides of the brake rotor allow for better contact with the back of the brake pad to help improve pad wear. The brake calipers come with a powder coated color finished to ensure a long good looking life under the harsh brake conditions or dust and heat. Each caliper piston is also made from stainless steel. Stainless has a lower coefficient of heat transfer than aluminum or regular steel to help keep the brake fluid cooler for longer. The pistons are also staggered in size within the caliper, to further promote even pad wear.
Brake pads are critical and each CorkSport BBK comes equipped with upgraded brake pads already installed in your 4-piston calipers. They fit in between a street pad and a full track pad in terms of aggressiveness so you’ll have good performance when the brakes are cold as well as when there is a heat in them. They are also quiet and not too dusty. We do still recommend an actual track pad for extensive track time, but they perform well as an in between set. If you want to change out the pads the CS BBK uses a very common size with plenty of options from all the big name brands which can be seen a little further down.
The CorkSport BBK is truly an all-in-one kit. We have included braided stainless steel lines to improve the brake pedal feel and make sure it stays firm and consistent. High strength billet caliper brackets are used to keep everything positioned correctly and securely. All hardware needed for the install is included and is corrosion resistant grade 12.9 bolts. As a final bonus, even with all the added size of the calipers and rotors, the CorkSport BBK weighs in at about 0.25lbs LESS
The following brake pads series may operate with the CorkSport 13” BBK. Other brake pad manufacturers may have pads design for this configuration that is not listed here.
It will take you 3 hours to install the CorkSport 3rd Gen Mazda 3/6 and Cx-5 BBK.

I purchased your big brake kit for my 2018 Mazda 6. Now I would like to install this kit on my Mazdaspeed 3. I see that you also list the same kit for the Mazdaspeed 3 on your website.
Could you please sell me the caliper mounting brackets separately, so that I can fit the kit properly?
Thank you very much for your support!

Installation is very straight forward because Corksport always provides pictured instructions. Being a bigger caliper and rotor, it fills in the wheel well nicely and really adds that WOW factor over OEM. Overall, whether you track your car or it's just a daily, this kit will not only add aesthetic to your car but give you the responsiveness and reassurance you need on the road.

Whether you are a serious driver that does track days frequently, or a daily driver with some spirited driving on the side - I’d say this is easily one of the best mods you can do. Not only does it greatly enhance your driving experience, it looks great while doing it too.

Installation was straightforward, thanks to the detailed instructions and included hardware. The kit is a direct bolt-on upgrade, requiring no modifications to the vehicle, but be aware that OEM flare nuts are kinda soft, and may be destroyed during installation. Since installing the CorkSport Big Brake Kit, I've noticed a more responsive brake pedal and reduced brake fade, even during aggressive driving. Overall, I'm extremely satisfied with this product and would highly recommend it to any Mazda 3 or Mazda 6 owner looking to enhance their driving experience.

Yeah driving fast is cool but that means nothing if you can't slow down for those tight corners or emergency braking situations. Even in traffic these have stopped me in situations the OE brakes may not have. This is a spectacular upgrade that is great for daily driven and track oriented mazdas alike. 10/10

Passengers are always impressed with the enhanced stopping capabilities this kit has. The brake pad options that the kit supports gives you plenty of options for a variety of needs.
