• Corrosion-related caliper service on high-mileage trucks and SUVs

Installation Notes

Confirm the caliper OE number before ordering, since this kit is listed for brake calipers OE No. 25848000 and 25848001. Match the 51mm piston diameter to the caliper being serviced, and verify front or rear application against the vehicle listing. Clean the caliper bore thoroughly before assembly and inspect the piston and sliding surfaces for wear or corrosion.

Quality Assurance
