About Centric Premium Semi-Loaded Disc Brake Calipers
The Centric Premium Semi-Loaded Disc Brake Calipers line provides a balance between fully loaded and bare calipers by including essential components such as the mounting bracket, abutment clips, and bleeder screw. This semi-loaded design simplifies installation while allowing users to reuse existing brake pads and mounting hardware if desired. The 141.66501 caliper benefits from this approach, offering a quality aluminum casting and phenolic piston for heat resistance and corrosion protection.
Detailed Product Description
This Centric disc brake caliper features a single 48mm phenolic piston designed to reduce heat transfer to the brake fluid, improving overall braking consistency. The aluminum caliper body provides a lightweight yet durable structure, suitable for the demands of mid-size trucks and SUVs like the Chevrolet Blazer and GMC Sonoma. The caliper includes a gray finish and comes with abutment clips and a mounting bracket to ensure proper alignment and secure installation. The inlet fitting uses a banjo style with an M10x1.0 thread diameter, matching OEM specifications for a direct replacement. Additionally, the bleeder screw is included with the correct M10x1.0 thread size to facilitate brake system bleeding during maintenance.
Common Applications and Problem Solving
- Replacement for worn or leaking disc brake calipers on Chevrolet, GMC, Isuzu, and Oldsmobile trucks and SUVs
- Addresses uneven brake pad wear due to caliper piston issues
- Resolves brake fluid leaks from damaged or corroded caliper bodies
- Improves brake pedal feel by restoring proper caliper function
- Suitable for vehicles requiring a floating caliper with a 48mm piston bore
Installation Notes and Tips
- Ensure compatibility with your vehicle’s make, model, and year before installation
- Use the included mounting bracket and abutment clips for proper caliper alignment
- Bleed the brake system thoroughly using the included bleeder screw to remove air
- Re-use existing brake pads if they meet wear specifications, as pads are not included
- Verify inlet fitting thread size (M10x1.0) matches your brake line connection
