Master Cylinder: Installation

Position the master cylinder on the brake booster. Refer to check push rod length.

Place the SST on the master cylinder. Turn the adjusting bolt until it bottoms in the push rod hole in the piston

Apply 19.7 in. Hg (500 mm Hg) vacuum to the power brake unit with a vacuum pump.

Fig 2: Increasing Vacuum
Invert the adjustment gauge used in Step 1 and place it on the power brake unit.
Measure the piston to push rod clearance between the end of the gauge and the push rod of the power brake unit. If standard value is not 0 in. (0 mm) , loosen the push rod lock nut and turn the push rod to make the adjustment.

NOTE: By making the above adjustment, the clearance between the push rod and piston (after installation of the brake master cylinder to the power brake unit) will be as shown in the table below.

PUSH ROD CLEARANCE CHART

Vacuum Applied To Unit	Push Rod-To-Piston Clearance
0 in. Hg (0 mm Hg)	0.016~0.024 in. (0.4~0.6 mm)
Approximately 19.7 in. Hg (500 mm Hg)	0.004~0.016 in. (0.1~0.4 mm)
