Installation Service Point
>A< Vacuum Hose Connection





1. Install the vacuum hose to the brake booster nipple as shown. Secure the hose using the hose clip.

CAUTION:
1. The check valve and the pipe part of the brake booster must not contact each other.
2. Connect so that the marking faces upwards.

2. Install the other end of the vacuum hose fully onto its port on the engine. Secure the hose using the hose clip.

Clearance Adjustment Between Brake Booster Push Rod And Primary Piston





Adjust the clearance (A) between the brake booster push rod and primary piston as follows:

Calculate clearance A from the B, C and D measurements. A = B-C-D

Standard value: 0.65 - 0.85 mm (0.0256 - 0.0335 inch)

NOTE: When brake booster negative pressure 67 kPa (9.7 psi) is applied, clearance value will become 0.1 - 0.3 mm (0.004 - 0.012 inch).





If the clearance is not within the standard value range, turn the push rod screw to achieve desired length.
