Details on Centric Premium Semi-Loaded Disc Brake Calipers
The Centric Premium Semi-Loaded Disc Brake Calipers line offers a balance between fully loaded and basic caliper assemblies. This semi-loaded caliper includes the mounting bracket and abutment clips, which simplifies installation while allowing reuse of existing pads and hardware if desired. The caliper casting is made from cast iron, providing strength and heat resistance necessary for consistent braking. The single steel piston with a 50.8 mm bore diameter ensures effective clamping force on the brake pads. This caliper is designed as a floating type, which allows for self-adjustment during braking to maintain pad contact and reduce uneven wear.
Product Application and Problem Solving
- Replacement for worn or damaged front or rear brake calipers on Mazda Miata
- Addresses issues with sticking or seized caliper pistons
- Resolves brake fluid leaks from caliper seals or bleeder screw
- Improves braking consistency by restoring proper caliper function
- Supports maintenance of brake system integrity with included mounting bracket and clips
Installation Notes and Tips
Installation requires removal of the old caliper and mounting bracket. Since mounting hardware and brake pads are not included, inspect existing components for wear and replace as necessary. The included bleeder screw facilitates proper brake fluid bleeding after installation. Ensure the inlet fitting type (banjo or open) and thread size (M10x1.0) match your vehicle’s brake line connections. Proper torque specifications should be followed for mounting bolts and brake line fittings to avoid leaks or damage.
