To check the amount of l i n i n g wear, remove the
wheel and tire assemblies. I f a visual inspection does
not adequately determine the condition of the l i n i n g ,
removal w i l l be necessary. Remove the shoe and l i n -
i n g assemblies (see Brake Shoe Removal).
Combined shoe and l i n i n g thickness should be
measured at the thinnest part of the assembly.
When the friction material (Fig. 168) on the rear
disc brake shoes is worn to a thickness of approxi-
mately 2.5 m m (.100 in.) the brake shoes must be
replaced.

Replace both brake shoes (inboard and outboard)
on both wheels whenever the brake shoes on either
side of the vehicle are replaced.
I f the brake shoes do not require replacement,
install the original brake shoes back i n the caliper.
Make sure each brake shoe is returned to its original
position on the wheel of the vehicle t h a t i t was
removed from.
D I S C BRAKE CALIPER INSPECTION
Check for piston f l u i d seal leaks (brake fluid i n and
around boot areas and lining) and for any ruptures
i n the piston dust boots. I f a dust boot is damaged
the dust boot and guide p i n bolt bushing are a
replaceable component of the rear caliper. Refer to
Rear Disc Brake Caliper Bushings i n the Disassem-
bly A n d Assembly section i n t h i s group of the service
m a n u a l for the service procedure to i n s t a l l new guide
p i n bushings and dust boots. I f a leak or other mal-
function is noticed d u r i n g the inspection of the rear
disc brake caliper the caliper w i l l require replace-
ment. The rear disc brake calipers are not service-
able and must be replaced w h e n inspection indicates
this is necessary.
CHASSIS TUBES AND HOSES
Flexible rubber hose is used at both the front and
rear brakes to make the hydraulic attachment
between the frame of the vehicle and the moveable
components of the vehicle's suspension. Inspection of
the brake hoses should be performed whenever the
brake system is serviced and every 7,500 miles or 12
months, whichever comes first (every engine oil
change). Inspect hydraulic brake hoses for severe
surface cracking, scuffing, or w o r n spots. Should the
fabric casing of the rubber hose be exposed due to
cracks or abrasions i n the rubber hose cover, the hose
should be replaced immediately. Eventual deteriora-
tion of the hose can take place w i t h possible burst
failure. F a u l t y installation can cause t w i s t i n g and
wheel, tire or chassis interference.
The steel brake t u b i n g should be inspected period-
ically for evidence of physical damage or contact w i t h
moving or hot components.

STOP LAMP SWITCH
(1) Remove stop lamp switch from its bracket by
rotating i t approximately 30° i n a counter-clockwise
direction.
(2) Disconnect w i r i n g harness connector from stop
lamp switch.
(3) Hold stop lamp switch f i r m l y i n one hand.
Then using other hand, p u l l outward on the plunger
of the stop lamp switch u n t i l i t has ratcheted out to
its fully extended position.
(4) I n s t a l l the stop lamp switch into the bracket
using the following procedure. Depress the brake
pedal as far down as possible. Then while keeping
the brake pedal depressed, install the stop lamp
switch into the bracket by aligning index key on
switch w i t h slot at top of square hole i n m o u n t i n g
bracket. When switch is fully installed i n the square
