Installation Notes

Compatible with rear left applications only for the listed Buick and Oldsmobile vehicles. Verify inlet and bleeder port sizing before installation; this unit uses M10x1.5 inlet and bleeder ports. Pads are not included. Follow OE brake fluid specifications and use fresh fluid from a sealed container. Silicone grease is used on floating caliper mounting pins.

Quality Assurance

Cardone remanufactures this caliper to OE-style standards and pressure-tests each unit before release. The process uses new premium components, including seals and service hardware, to support reliable brake performance and consistent fit. The remanufacturing process also reduces energy and raw material use compared with producing a new part.
