3. Adjust clearance by turning adjusting screw of piston rod.
Special Tool
(B): 09952-16010
Reference
When adjusted as above, if negative pressure is applied to booster with engine at idle, piston to piston rod clearance "a" should become 0.25 - 0.50
mm (0.010 - 0.020 inch).
INSPECT BOOSTER OPERATION
There are two ways to perform this inspection, with and without a tester. Ordinarily, it is possible to roughly determine its condition without using a
tester.
NOTE: For this check, make sure that no air is in hydraulic line.
INSPECTION WITHOUT TESTER
Check Air Tightness
1. Start engine.
2. Stop engine after running for 1 to 2 minutes.
3. Depress brake pedal several times with the same load as in ordinary braking and observe pedal travel. If pedal goes down deep the first time but its
travel decreases as it is depressed the second and more times, air tightness is obtained.
