PARAGON 4-Piston Rear Big Brake Kit – Toyota GR Yaris (GXPA16) / GR Corolla (GZEA14)
The Paragon 4-piston rear big brake kit is a complete, bolt-on rear upgrade for the Toyota GR Yaris and GR Corolla. Paragon PA025 4-piston calipers and fully floating 2-piece rotors add braking control, cooling and consistency, and the kit retains the OEM parking brake function.
Choose 355 x 32mm rotors, a hard anodised or ENP caliper finish and Paragon P2, P3, R5 or R7 pads. Piston sizes are matched to the car, so the kit works with the OEM ABS and master cylinder.
Note: Pre-assembled rear axle kit, bolt-on installation. Retains OEM parking brake function. Installation by a professional is recommended.
