Product Line Details: Centric Premium Semi-Loaded Disc Brake Calipers
The Centric Premium Semi-Loaded Disc Brake Calipers line offers semi-assembled calipers that include essential components such as mounting brackets and abutment clips, simplifying installation. This product line focuses on delivering reliable braking components with durable cast iron construction and steel pistons, tailored for specific vehicle applications like the Mazda Protege series.
Technical Description and Features
This floating disc brake caliper features a single piston design with a 57mm diameter piston made of steel, providing consistent hydraulic pressure for effective braking. The caliper casting is made from cast iron, offering durability and resistance to heat generated during braking. The caliper includes a mounting bracket and abutment clips, but does not come with brake pads or mounting hardware bolts. The inlet fitting supports both banjo and open types with a 10mm thread diameter (M10x1.0), and the bleeder screw is included with an M7x1.0 thread size for easy brake fluid bleeding. The gray finish helps protect against corrosion and wear.
Applications and Problem Solving
- Replacement for worn or damaged brake calipers on Mazda Protege and Protege5
- Addresses issues with uneven brake pad wear due to caliper malfunction
- Resolves brake fluid leakage by providing a new bleeder screw and proper sealing
- Improves braking response by restoring proper piston movement
- Supports safe vehicle operation by maintaining effective hydraulic brake function
Installation Notes and Tips
Ensure compatibility with Mazda Protege or Protege5 before installation. This caliper requires the use of existing brake pads as they are not included. Mounting bracket and abutment clips are included, but mounting bolts must be reused or sourced separately. Properly torque all mounting hardware and bleed the brake system using the included bleeder screw to remove air and ensure optimal brake performance.
