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 key components such as bleeder screws and abutment clips, but exclude pads and mounting hardware. This approach allows for easier installation and maintenance while ensuring compatibility with specific vehicle models like the Jeep TJ and Wrangler. The use of cast iron and phenolic pistons in this line balances durability with corrosion resistance.

Technical Specifications and Features

This disc brake caliper features a floating design with a single piston measuring 1.89 inches (48mm) in diameter, made from phenolic material to reduce heat transfer and prevent corrosion. The caliper body is cast iron, providing structural integrity and resistance to wear. It includes a bleeder screw with a 3/8"-24 thread size and a banjo-type inlet fitting for brake line connection. Abutment clips are included to secure the brake pads, although pads and mounting hardware are not part of this assembly. The caliper is designed for the leading axle position on Jeep TJ and Wrangler vehicles.

Common Applications and Problem Solving

• Replacement of worn or damaged front disc brake calipers on Jeep TJ and Wrangler
• Addressing brake fluid leaks due to faulty bleeder screws or caliper seals
• Improving brake pedal feel by restoring proper piston movement
• Resolving uneven brake pad wear caused by caliper sticking
• Upgrading to a durable cast iron caliper for extended service life

Installation Notes and Tips

Installation requires removal of the existing caliper and proper cleaning of the mounting surface. Since mounting hardware and brake pads are not included, ensure compatible pads and hardware are sourced separately. Bleeder screws are included, facilitating brake fluid bleeding during installation. Verify inlet thread size (3/8"-24) and fitting type (banjo) match your brake lines. Proper torque specifications should be followed to avoid damage to the caliper or mounting points.
