xPart Overview
The Rear Left + Right Brake Calipers (2-piece set, OEM reference 18B5118 / 18B5119) is a precision aftermarket replacement for the rear brake system on the 2008-2013 Cadillac CTS (2nd generation). Calipers provide the hydraulic clamping force behind your rear brake pads; replacing a leaking or seized caliper restores balanced rear braking and prevents uneven pad wear.
