Master Cylinder Push Rod Clearance
NOTE:
Master cylinder push rod-to-piston clearance must be checked and adjusted before installing master cylinder.
NOTE:
Master Cylinder Push Rod Clearance Adjustment procedures are not available for MDX models.
- Mount Push Rod Adjustment Gauge (07JAG-SD40100) on master cylinder. Rotate adjuster nut until top of center shaft contacts end of secondary piston without changing piston position. See Fig 1 .
- Remove push rod adjustment gauge from master cylinder, and install on brake booster. Tighten master cylinder nuts to specification. See TORQUE SPECIFICATIONS . Using engine or outside vacuum source, apply a continuous 20 in. Hg, on 3.5RL & 3.2TL models, or 30 in. Hg on 3.2CL models, vacuum to brake booster.
- Using a feeler gauge, ensure clearance between gauge body and adjusting nut is 0-.016" (0-.40 mm) on 3.2CL & 3.2TL, or 0-.008" (0-.20 mm) on 3.5RL. See Fig 2 . If clearance is not as specified, go to next step.
- On 3.2TL, loosen star lock nut and rotate adjuster nut in or out to adjust clearance. On 3.2CL & 3.5RL, remove adjustment gauge. Hold push rod, and rotate adjuster on booster push rod in or out to adjust clearance. DO NOT pull push rod out of brake booster. Tighten star lock nut securely.
