Vacuum Brake Booster: Adjustments
Brake Booster Pushrod Clearance Adjustment
Special Tools Required
Booster piston holder 070AB-SJA0100
NOTE:
^
Brake booster pushrod-to-piston clearance must be checked and readjusted before installing the master cylinder.
^
The master cylinder assembly comes with the specific plate that adjusts the clearance between the brake booster and the specific master cylinder
piston.
^
Every time you change the master cylinder; use only the enclosed plate to check the brake booster pushrod clearance.
^
Do not use anything other than the enclosed plate to check the clearance. Make sure to discard the plate supplied with master cylinder after its use.
^
Brake booster has to be on the vehicle before the 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, then install the brake booster to the vehicle.
1. Measure the clearance between the plate (A), supplied with master cylinder, and the brake booster pushrod (B). Make sure that the enclosed plate
touches contacting surface (C) between the master cylinder and brake booster. If there is a gap between the tip of the plate and the pushrod (D) or
a gap between the contacting surface and the plate (E), go to step 2.
2. Use the special tool to hold the nut, and turn the 6 mm pushrod (A) clockwise or counterclockwise to adjust the pushrod inward or outward.
