Brake Master Cylinder: Inspection
- INSPECT AND ADJUST BRAKE BOOSTER PUSH ROD NOTE: Make an adjustment with the brake booster assembly having no vacuum. (Depress the brake pedal several times with the engine off.)
HINT:
Adjustment of the brake booster push rod is required if the brake master cylinder sub-assembly is replaced with a new one. The adjustment is not necessary if the brake master cylinder sub-assembly is reinstalled and the brake booster assembly is replaced with a new one.
- Apply the chalk to the tip of an accessory tool.
HINT:
An accessory tool is enclosed with a new brake master cylinder sub-assembly.
- Place the accessory tool on the brake booster assembly.
- Measure the clearance between the brake booster push rod and accessory tool.
Clearance:
0 mm (0 in.)
HINT:
Adjust the clearance in the following cases:
- If there is a clearance between the accessory tool and the shell of the brake booster (floating accessory tool), the push rod is protruding too far.
- If the chalk does not stick on the tip of the brake booster push rod, the push rod protrusion is insufficient.
- If clearance is outside the specified range, fix the push rod using SST and adjust the length of the protruding adjusting bolt.
SST 09737-00020
HINT:
When adjusting the push rod, depress the brake pedal sufficiently so that the push rod sticks out.
- Apply the chalk to the tip of an accessory tool.
