Standard value (A): mm (6.9-7.1 in.)

value, adjust as follows.
(a)Disconnect the stop switch connector, loosen
the lock nut, and move the stop light switch to
a position ‘where it does not contact the brake
pedal arm,.,
(b) Adjust the brake pedal height by
operating rod with pliers (with the operating rod

height is obtained.
(c) Screw in the stop

the brake, pedal- stopper (just before the brake
pedal is caused to move). Back off the stop light

2. BRAKE PEDAL FREE PLAY (1) With the engine stopped, press the brake pedal two
or three times. After eliminating the vacuum in the
power brake booster, press the pedal down by hand,
and confirm that the amount of movement before
feeling resistance (the free play) is within the st andard
value range.
Standard value (B): 3-8 mm in.)
(2) If the free play exceeds the standard value, it is
probably due to excessive play between the
pin and brake pedal arm.
Check for excessive clearance and replace faulty pa rts

For simple checking of the brake booster operation,
carry
out the following tests: 1. Run the engine for one or two minutes; and then turn
the engine off. If the pedal depresses fully the first time but gra dually
becomes higher when depressed succeeding times, the
booster is operating properly. If the
height remains
unchanged, the booster is defective.
2.With the engine stopped, step on the brake pedal se veral
times.
Then step on the brake pedal and start the engine.
If the pedal moves downward slightly, the booster i s in

defective.
3. With the engine running, step on the’ brake peda l and’
then stop the engine. Hold the pedal depressed for 30 seconds. If the ped al,
