Brake Master Cylinder: Adjustments
NOTE: Master cylinder pushrod-to piston clearance must be checked and adjustments made, if necessary, before installing master cylinder.
1. Set the special tool on the master cylinder body; push in the center shaft until the top of it contacts the end of the secondary piston by turning the
adjusting nut.
2. Without disturbing the center shaft's position, install the special tool upside down on the booster.
3. Install the master cylinder nuts, and tighten to the specified torque.
4. Connect the booster in-line with a vacuum gauge 0 - 101 kPa (0 - 760 mmHg, 30 in.Hg) to the booster's engine vacuum supply, and maintain an
engine speed that will deliver 66 kPa (500 mmHg, 20 in.Hg) vacuum.
Clearance: 0 - 0.4 mm (0 - 0.02 inch)
5. With a feeler gauge, measure the clearance between the gauge body and the adjusting nut as shown.
NOTE: If the clearance between the gauge body and adjusting nut is 0.4 mm (0.02 inch), the pushrod to-piston clearance is 0 mm. However, if
the clearance between the gauge body and adjusting nut is 0 mm, the pushrod-to-piston clearance is 0.4 mm (0.02 inch) or more. Therefore, it
must be adjusted and rechecked.
Booster Pushrod Adjustment
6. If clearance is incorrect, loosen the star locknut and turn the adjuster in or out to adjust.
