Rebuild the hydraulic half of your Cadillac's disc brakes with the A1 CARDONE Remanufactured Unloaded Disc Brake Caliper 18-B4878. This unloaded caliper ships with its mounting bracket and drops in as a direct-fit replacement for the 2003-2008 Cadillac CTS and 2005-2008 Cadillac STS — see the Buyer's Guide tab for engine-level fitment.
Each unit is remanufactured to CARDONE's quality standards and 100% pressure-tested, so it delivers consistent hydraulic clamping when a worn or leaking original caliper is the cause of poor braking. Because it's unloaded, brake pads are not included.
Calipers wear as a pair, so replacing both sides together is best practice for even, balanced braking; this listing covers a single caliper.
This part cross-references / interchanges with the following part numbers:
Does this caliper come with a mounting bracket?
Yes. It's an unloaded caliper supplied with its mounting bracket, plus new bleeder screws, and new banjo bolts, washers, stainless steel clips and mounting pins where applicable.
Are brake pads included?
No. This is an unloaded caliper, so it does not include brake pads. Reuse serviceable pads or install a new set.
What vehicles does 18-B4878 fit?
It's a direct-fit replacement for the 2003-2008 Cadillac CTS and 2005-2008 Cadillac STS. Check the Buyer's Guide tab to confirm the exact fit for your vehicle.
Is this caliper tested before shipping?
Yes. Each remanufactured unit is 100% pressure-tested and rebuilt with brand-new premium components for consistent hydraulic performance.
Should I replace both calipers at the same time?
Replacing calipers as a pair is best practice for even, balanced braking, though this listing covers a single caliper.
