varies depending on installation position of booster push
rod clevis and stop light switch.

preventives, lubricant, etc.) to following
sections.
* Stop light switch (1) (including its tip end)

brake switch, check that no oil or grease is
attached to switch contacting section on
brake pedal side or tip end of switch.
Wipe off oil or grease being attached.

(3).
Clearance "b" between end of thread and brake
pedal stay
"b": 1.5 – 2.5 mm (0.06 – 0.10 in.)

Brake Flexible Hose and Pipe Check

The brake hose assembly should be checked for road
hazard damage, for cracks and chafing of the flexible
hose, for leaks and blisters. A light and mirror may be
needed for an adequate inspection. If any of the above
conditions are observed on the brake flexible hose, it is
necessary to replace it.
Inspect the pipe for damage, cracks, dents and
corrosion. If any defect is found, replace it.
