Brake Master Cylinder: Inspection
- INSPECT AND ADJUST BRAKE BOOSTER PUSH ROD (for TMMK Made)
NOTE:
- Make an adjustment with no vacuum in the brake booster assembly. (Depress the brake pedal several times with the engine stopped.)
- The brake booster made by TMC does not need adjustment.
HINT:
- Adjustment of the brake booster push rod is required when the brake master cylinder sub-assembly is replaced with a new one.
- Adjustment is not necessary when the removed brake master cylinder sub-assembly is reused and the brake booster assembly is replaced with a new one.
- Apply chalk to the tip of the 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.
Standard 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 the clearance is not as specified, adjust the push rod length by holding the rod using SST and turning the tip of the rod using a socket driver (7 mm, 0.28 in.).
SST 09737-00020
HINT:
Check the push rod clearance again after adjustment.
