Removal and Installation
MASTER CYLINDER REMOVAL/INSTALLATIONCaution Before removing the master cylinder, be sure to disconnect the vacuum hose (with check valve) from the power brake unit. Removing the master cylinder with vacuum remaining in the power brake unit will cause the master cylinder piston to pop out and drain the brake fluid.
1. Remove in the order indicated in the table.
2. Install in the reverse order of removal.
RETAINER REMOVAL NOTE
1. Remove the retainer as shown.
2. Remove the seal and plate component.
RETAINER INSTALLATION NOTE
1. Remove the seal and plate component, and install the power brake unit gasket.
2. Adjust the push rod clearance as follows.
1) Attach the Special Service Tool (SST) to the power brake unit as shown in the figure, and tighten the locknuts to the specified torque.
Tightening torque
9.9 - 15.6 Nm (100 - 160 kgf-cm, 87 - 138 inch lbs.)
2) Apply 500 mm-Hg (19.7 inch-Hg) vacuum using a vacuum pump.
3) Measure depth L of the gauge rod.
^ If not as specified, use the SST to adjust the push rod to the proper length.
Depth L
35.1 mm (1.38 inch)
4) Verify depth L of the gauge rod.
3. Install the retainer and the seal and plate component using the SST.
4. Apply the specified grease (supplied in the repair kit) to the seal and plate component.
5. When installing the master cylinder into the power brake unit, be sure to align it correctly, fitting the master cylinder squarely into the power brake unit seal. Do not roll the lip of the power brake unit seal.
