Welcome to the CorkSport 13” Big Brake Kit for the 2014-2018 Mazda 3, 2014+ Mazda 6 and 2013+ 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.

What wheel specs would I need when purchasing new wheels to fit the brake kit?
Although we do not have any specific wheel specs we do have this took to help determine if the wheels you have/want will work: https://corksport.com/support/instructions/AXM-3-413-Wheel-Fitment-Guide.pdf
Would these work with konig oversteers with a 35 offset
Please use our wheel fitment template to verify fitment: https://corksport.com/support/instructions/AXM-3-413-Wheel-Fitment-Guide.pdf
Hello. I have 20x9 +38mm wheels. Will this work as is or will I need spacers? Thanks.
Please review the BBK wheel fitment guide here. If you print it off and follow the instructions, it will show you exactly how that brake would sit in your wheel. chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://corksport.com/support/instructions/AXM-3-413-Wheel-Fitment-Guide.pdf
Can the kit be mounted to the rear?
Not as is, that would take some custom work.
Which brake fluid is recommended?
Any reputable brand DOT4 fluid will work.
Do I need wheel spacers for this kit for the 3rd gen. Mazda 6 if it already has 20" aftermarket wheels on it ???
That will depend on the offset, print the template to verify.
Are you guys going to make a version that doesnt require wheel spacers and extended wheel studs?
No, there will not be a version with smaller calipers.
What would be the package size and weight?
68lbs, 16x16x16
Will these fit the CX-5 grand toouring model with 19inch wheels without spacers?
Due to OEM wheel offset, spacers will be needed for installation.
Will you be making a match to these for the rear?
Due to the electronic e brake and projected overall cost, no.
Can you do a custom color?
We can only do the colors listed on the page, sorry.
I saw the post above but Are you working on a set for the 2019 turbo CX-5 ?
This kit will fit that model.
Will the 14-18 kit transfer to the 21 Turbo when we get one?
No, the brake kits are different between the generations due to changes from Mazda.
Does this set include front and rear?
The brake kit is for the fronts only.
