Details on Centric Premium Semi-Loaded Disc Brake Calipers

The Centric Premium Semi-Loaded Disc Brake Calipers line is designed to provide a balance between ease of installation and reliable braking performance. This semi-loaded caliper includes essential components such as the mounting bracket, abutment clips, and bleeder screw, but does not include brake pads or mounting hardware. The cast iron caliper body ensures strength and heat resistance, while the single 43mm steel piston provides consistent pressure on the brake pads. The floating caliper design allows for smooth movement and even pad wear, which is critical for maintaining braking efficiency on the Mazda RX-8.

Installation Notes and Tips

Installation requires removal of the old caliper and proper mounting of the included bracket and abutment clips. Note that brake pads and mounting hardware bolts are not included and must be sourced separately. Ensure the bleeder screw is properly tightened and bled to remove air from the brake system. The inlet fitting supports both banjo and open types with M10-1.00 thread size, compatible with standard brake lines on the Mazda RX-8. Verify all connections for leaks and proper fitment before road testing.
