Product Details

This Cardone brake caliper is remanufactured to OE fit standards and finished with a rust-inhibiting coating to help maintain the original equipment appearance. The phenolic piston design is used on the listed Cadillac brake code JL9 applications, and the caliper bracket is included for the specified fitments. This part cross-references Cadillac 88959948 and 89060360 for the same application.

Compatible with 2003-2008 Cadillac CTS and 2005-2008 Cadillac STS front brake positions, this caliper is a direct replacement for vehicles requiring the correct forward-mount or rear-mount front caliper configuration. Use part number 18-B4879 when servicing the front right or front left brake assembly on the listed Cadillac models.

What It Helps Fix

  • Brake drag or uneven pad contact at the front wheel
  • Leaking or sticking caliper operation
  • Corrosion-related caliper performance issues
  • Soft or inconsistent front brake response caused by caliper wear
  • Noise or pull during braking when the caliper is no longer operating correctly

Installation Notes

Verify the brake code and caliper position before removal, especially on Cadillac CTS and Cadillac STS JL9 applications. This part is listed for front right and front left positions only, with forward-mount and rear-mount configurations noted by application. Always use the brake fluid specified by the vehicle manufacturer and bleed the system thoroughly after installation. The product includes installation hardware, and the bracket is included where applicable.

Quality Assurance

Cardone remanufactures this caliper using new premium components, then pressure-tests each unit to confirm brake performance. Rubber seals are replaced with high-temperature EPDM material, and the caliper is treated with a rust inhibitor to support long-term service life. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
