Installation Notes

Confirm the thread size before installation: this kit uses 3/4-16 threads. Because the hardware is marked one-time use, replace it during service rather than reusing removed components. Verify the exact vehicle application, including model year and any notes such as the 1983 Ranger cutoff date or the 1975-1979 F-250 1 piston caliper note, before assembly.
