Product Description

The EBC S12KR1284 rear brake kit is a full performance and replacement upgrade kit designed for Mazda 3 vehicles from 2006 through 2013, including the MazdaSpeed 3 variants. This kit combines EBC's low-dust Redstuff ceramic brake pads with premium RK smooth rotors, offering enhanced stopping power and cleaner wheels compared with many standard rear brake setups. The aramid fiber reinforced pad compound delivers reliable engagement for everyday driving and spirited street use, while the patented Brake-In coating helps accelerate the bedding-in process for consistent braking performance soon after installation.

Included rotors feature a corrosion-resistant anti-rust coating and are fully balanced and run-out tested to help minimize vibration and extend service life. Designed as a direct OEM-style replacement for the rear brakes on compatible Mazda 3 models, installation requires no modifications to existing caliper mounts or hardware. Fitment is confirmed for 2006-2013 Mazda 3 vehicles equipped with 2.3L and 2.5L engines; coverage beyond these years is unconfirmed at the time of listing. This rear brake kit is an ideal choice for owners looking to refresh worn brakes with a performance-minded upgrade that enhances brake feel, reduces dust, and improves overall braking performance.
