Product Details

Centric 141.66506 is built from an aluminum caliper casting and finished with a rust preventative coating to help protect the housing after remanufacturing. The floating design uses two pistons and an M10x1.0 inlet thread with a banjo fitting, along with an M10x1.0 bleeder screw thread. This caliper is inspected and pressure tested to verify operation and fitment before it leaves the remanufacturing process. The Centric Premium Semi-Loaded Disc Brake Calipers line focuses on OE-style replacement coverage for GM rear brake service, including applications such as Chevrolet Silverado 1500 rear left and GMC Yukon rear left.

This part cross-references Raybestos Brakes FRC11169 for the same application.

What This Caliper Helps Address

• Uneven rear braking caused by a sticking or worn caliper
• Brake fluid leakage at the caliper body or bleeder area
• Corrosion on the caliper housing from age and road exposure
• Poor piston movement that affects pedal feel and brake balance
• Fitment issues when replacing the rear left caliper on GM truck and SUV platforms

Installation Notes

Verify rear left fitment by year, make, model, and brake configuration before installation. This caliper uses a bracketed floating design and is listed with a mounting bracket included where applicable, so confirm the existing bracket and hardware arrangement on the vehicle. Bleeder screw and abutment clips are included; pads are not included. Always bleed the brake system after installation and inspect the banjo connection, inlet thread, and mounting points for proper sealing and alignment.

Quality Assurance

Centric remanufactures this caliper to a like-new condition, then tumble blasts and applies an anti-corrosion finish for added rust protection. Each unit is pressure tested and inspected to help ensure proper operation and fitment. Centric is a long-established brake component manufacturer with product coverage across OEM replacement and performance brake categories.
