To install:
  1. Place the caliper over the installed pads and bolt to the pins in the caliper retainer.
  2.  
  3. Use new gaskets on the banjo bolt and tighten to 25 ft. lbs. (35 Nm).
  4.  
  5. On vehicles that have long pins below the threads of the caliper bolt, torque the bolt to 54 ft. lbs. (75 Nm).
  6.  
  7. On vehicles that have short bolts with no pin beyond the threads, torque the bolt to 20 ft. lbs. (27 Nm).
  8.  
  9. Bleed the brake system.
