NOTE:
^
Brake booster pushrod to piston clearance must be checked and readjusted before installing a new master cylinder.
^
The master cylinder assembly comes with a tool that must be used to adjust the clearance between the brake booster pushrod and the master
cylinder piston.
^
Use only the tool that comes with the new master cylinder to check the pushrod clearance. Do not use any other tool.
^
Make sure to discard the tool supplied with the master cylinder after its use.
^
The brake booster must be installed on the vehicle before doing the pushrod clearance adjustment.
^
If the booster is removed, check the pushrod length (A) as shown. If the length is incorrect, loosen the pushrod locknut (B), and turn the yoke (C)
in or out to adjust.
1. Measure the clearance between the plate (A) supplied with master cylinder and brake booster pushrod (B). Make sure that the tool is lying flat
against the surface (C) of the brake booster, and that the tip of the tool contacts the pushrod. if the tool will not lie flat (D) or there is a gap
between the tool and the pushrod, go to step 2 to adjust the pushrod in or out.
2. If the clearance is incorrect, use the booster piston holder to hold the pushrod (A) and turn the adjusting screw (B) clockwise to inward or
counterclockwise to outward.
