1987 SUZUKI GRAND VITARA height

BRAKE PEDAL FREE HEIGHT ADJUSTMENT
Brake pedal height is normal if brake pedal is
as high as clutch pedal.
1) When booster push rod clevis has been
reinstalled, it is important that measurement
between booster mounting surface (with a
gasket attached) and the center of clevis
pin hole is adjusted within 125.5 mm -
126.5 mm (4.94 - 4.98 in.). (See page
19-37.)
2) When stop light switch has been removed,
refer to the following STOP LIGHT SWITCH
ADJUSTMENT for proper installation.
The services in above steps 1) and 2) may
affect brake pedal height.
STOP LIGHT SWITCH ADJUSTMENT
Adjustment should be made as follows when
installing the switch.
Pull up brake pedal toward you and while
holding it there, adjust switch position so that
clearance between the end of thread and brake
pedal contact plate (shown as “A” in figure) is
within 0.5 -1 .O mm (0.02 - 0.04 in.). Then
tighten lock nut to specified torque.

EXCESSIVE PEDAL TRAVEL CHECK
1) Start the engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximate-
ly 30 kg (66 Ibs) load, measure pedal arm to
wall clearance “B”.It mustn’t be less than
75 mm (2.95 in.).
Fig. 19-8-4
4) If clearance “B” is less than 75 mm (2.95 in.),
the most possible cause is either rear brake
shoes are worn out beyond limit or air is in
lines.
Should clearance “8” remain less than 75 mm
(2.95 in.) even after replacement of brake
shoes and bleeding of system, other possible
but infrequent cause is malfunction of rear
brake shoe adjusters or booster push rod
length out of adjustment for the car with
brake booster.
See p. 19-22 for brake shoe inspection.
See p. 19-46 for bleeding brake system.
Remove brake drums for adjuster inspection.
(See p. 19-23.) If defective, correct or replace.

4) If pedal travel doesn’t change, air tightness
isn’t obtained.

NOTE:
If defective, inspect vacuum lines and sealing
parts, and replace any faulty part.
When this has been done, repeat the entire test!
Check Operation
1) With engine stopped, depress brake pedal
several times with the same load and make
sure that pedal travel doesn’t change.
Fig. 19-8-19 \
Check Air Tightness Under Load
1) With engine running, depress brake pedal.
Then stop engine while holding brake pedal
depressed.
-Hold
Fig. 19-8-20
2) Hold brake pedal depressed for 30 seconds.
If pedal height does n.ot change, condition
is good. But it isn’t if pedal rises.
Fig. 19-8-18
2) Start engine while depressing brake pedal. If
pedal travel increases a little, operation is
satisfactory. But no change in pedal travel
indicates malfunction.
