Replacement rear disc brake caliper for the specific Cadillac, Chevrolet, and GMC applications listed below. Reference numbers 18B4726 and 18B4727 are included for comparison.

Critical fitment warning: The source confirms rear-disc-brake fitment but does not identify which reference number corresponds to the rear-left or rear-right side. It also does not specify package quantity, piston count or diameter, mounting-bracket style, rotor size, drivetrain, axle ratio, payload or GVWR package, brake option, or production-date restrictions. Confirm the VIN, original caliper casting and side, rear disc-brake configuration, mounting points, hose connection, bleeder position, bracket, rotor dimensions, and reference number before ordering.

Reference Numbers

18B4726, 18B4727.

The source does not assign these references to left and right sides. Match the required rear side and original caliper before ordering.

Package Contents

The source identifies a rear disc brake caliper but does not explicitly confirm package quantity or whether a mounting bracket, brake pads, slide pins, parking-brake components, hardware, banjo bolt, copper washers, hose, or brake fluid is included. Review the product images and confirm the required side, quantity, and contents before purchase.

Installation Notes

Brake-system work is safety-critical and professional installation is strongly recommended. Confirm the vehicle has the matching rear disc-brake system and verify the correct side before installation; the bleeder must be positioned correctly for complete bleeding. Inspect the rotor, pads, hose, parking-brake system, mounting hardware, wheel bearing, and opposite-side caliper. Use new sealing washers where required, follow the vehicle manufacturer’s torque specifications, fill with the specified brake fluid, and bleed the hydraulic system completely. Check for leaks, verify a firm pedal and correct wheel rotation, adjust and test the parking brake if applicable, then perform a cautious low-speed brake test in a safe area before normal road use.
