Detailed Product Description
This Centric Premium Semi-Loaded Disc Brake Caliper is a floating type caliper constructed from cast iron, providing a robust and heat-resistant component suitable for the braking demands of the Lexus RX300. The caliper features a single steel piston with a 60mm diameter, designed to apply even pressure to the brake pads. It comes semi-loaded, meaning it includes the mounting bracket and abutment clips but does not include brake pads or mounting hardware. The inlet fitting supports both banjo and open types with an M10x1.0 thread diameter, facilitating compatibility with standard brake lines. Additionally, the caliper includes a bleeder screw with an M7x1.0 thread size to assist in proper brake fluid bleeding during installation or maintenance.
The Centric Premium Semi-Loaded Disc Brake Calipers product line focuses on providing semi-assembled calipers that reduce installation time while maintaining OEM-level quality. This line is designed to offer a balance between fully loaded and bare calipers, supplying essential components like brackets and clips to streamline the brake system rebuild process.
