Master Cylinder Push Rod Clearance

NOTE: Master cylinder push rod-to-piston clearance must be checked and adjusted before installing master cylinder.
  1. Mount Push Rod Adjustment Gauge (07JAG-SD40100) on master cylinder. Rotate adjuster nut until top of center shaft contacts end of secondary piston. See Fig 1.
  2. Remove push rod adjustment gauge from master cylinder, and mount it upside down on brake booster. Tighten master cylinder nuts to 11 ft. lbs. (15 N.m). Using engine or outside vacuum source, apply a minimum of 20" Hg vacuum to brake booster.
  3. Using a feeler gauge, verify clearance between gauge body and adjusting nut is 0-0.016" (0-0.40 mm). See Fig 2. If clearance is not as specified, go to next step.
  4. Loosen star lock nut and rotate adjuster in or out to adjust clearance. DO NOT pull push rod out of brake booster.
