Help keep braking firm and consistent on your Cadillac with the A1 CARDONE caliper 18-B4878, a remanufactured unloaded disc brake caliper that installs as a direct-fit replacement on the 2003-2008 Cadillac CTS and 2005-2008 Cadillac STS. Because it ships unloaded, brake pads are not included, but the mounting bracket comes with it so the assembly can clamp the pads against the rotor from the factory location.
Each unit is remanufactured from an original-equipment caliper and 100% pressure-tested for consistent brake performance.
- New premium internals: durable pistons resistant to cracking and pitting, plus rubber seals replaced with new high-temperature EPDM rubber for extended life.
- Ready to install: includes the mounting bracket, a new bleeder screw for trouble-free bleeding, and a plastic cap plug protecting the brake port thread; new banjo bolts, washers, stainless steel hardware clips and mounting pins are included where applicable.
- Corrosion protection: treated with a specially formulated rust inhibitor and kept in the original equipment finish.
The caliper uses hydraulic pressure to press the brake pads against the rotor. If a seized, leaking, or dragging caliper is behind uneven pad wear, a soft pedal, or a pull to one side, this unit replaces it. The catalog lists it for the front left and front right positions; for balanced braking, it is best to replace both front calipers together as a matched pair, and this listing is for one caliper. See the "Vehicles it fits" section to confirm the exact application for your vehicle.
