The CorkSport Advantage
Complete Kit:
The CS rear big brake kits are complete kits that include the required parts to operate the rear parking brake using either the OEM electronic parking brake motor on newer models or a mechanical-hydraulic unit designed to work with the original parking brake cables on earlier models.
- The CorkSport Rear Big Brake Kits DO NOT include wheel spacers or studs.
- The CorkSport Rear Big Brake Kits shipped with CS "Sport" pads, same as our 13" front BBKs.
- All kits include a left and right caliper, brake rotors, caliper mounting brackets, mounting hardware, and stainless steel coated brake lines.
- All kits feature 2 piece rotor design with 330mm x 28mm rotor rings and an anodized aluminum mounting hat.
- Mechanical parking brake kits utilize a 4-piston caliper with 24mm and 28mm pistons.
- Electronic parking brake kits use a 6-piston caliper with 20mm outer (qty 4) and 24mm (qty 2) inner pistons.
Performance Advantage:
Stop with confidence with a big brake kit from CorkSport! The Rear Brake Kits are designed to deliver optimum braking performance for your Mazda using upgraded components that far outshine the OEM brakes. We've selected premium materials that balance heat, weight, and force to deliver a superb braking experience.
Performance Brake Rotor Design:
The biggest improvement of the CorkSport rear BBKs is the rotor size upgrade. The kits use a 330mm (13inch) diameter rotor, designed to match the CorkSport BBK front rotors. The larger rotor offers better braking torque, just like how a bolt is easier to loosen with a longer ratchet. Each rotor is an optimized two-piece design with an aluminum center to keep weight to a minimum while helping to transfer heat out of the rotor rings. Directionally curved vanes draw air through the rotor while spinning, allowing the rotor to cool more efficiently. The faces of the rotors also feature a slotted pattern that sweeps away brake dust, gases, and other debris that may affect braking performance.
Multi-Piston Calipers:
The CS Rear Big Brake Kits offer multi-piston calipers. For electronic parking brake applications, a 6-piston caliper with 20mm outer pistons and 24mm center pistons is used. For mechanical parking brake applications, a 4-piston caliper design with 24mm and 28mm pistons. These are the next largest improvement over the OEM brake system. The calipers are made from forged aluminum for optimum strength and rigidity for consistent performance no matter how hard you push them. The multi-piston design ensures maximized brake pad area and consistent and even pad pressure and wear. The piston sizes are staggered to further promote even pad wear. Finally, each caliper is powdercoated in one of seven stylish colors!
Upgraded Pads, Lines, & Hardware:
Each CorkSport RBBK comes equipped with our blue "Sport" brake pads pre-installed calipers. This pad material bridges the gap between a street pad and a full track pad. You have good performance when the brakes are cold, which gets even better with a little heat, yet they are quiet and not too dusty. Don’t worry, when it comes time to replace pads, the CS BBK uses a very common size with plenty of options for CorkSport or one of the big-name brake brands. Each BBK also comes with all new braided stainless steel brake lines for a stiff and consistent brake pedal feel. Install the kit easily with included high-strength billet caliper brackets and grade 12.9 mounting hardware. We even include touch up paint in your BBK color for any damage that may occur over time!
Please Note:
- Front BBK calipers pictured above are for color reference only.
- OEM wheels require the use of a wheel spacer for operation.
- Depending upon the size of the spacer required, extended wheel studs may be needed.
- Some aftermarket wheels may also require the use of a wheel spacer for the operation of this Rear BBK.
- Rear Only Big Brake Kits have unique wheel fitment/clearance requirements by model/year.
- To verify clearance, refer to the rear-only fitment template attached at the bottom of our model/year specific Rear BBK install instructions.
