1-3. CHASSIS AND BODY
30. CLUTCH PEDAL INSPECTION
1) Check clutch pedal height. It should be the
same as brake pedal height.
2) Check clutch pedal free travel.
Clutch pedal free travel20 - 30 mm
(0.8 - 1.1 in.)
For the details of the above steps 1) and 2),
refer to MAINTENANCE SERVICE (p. 11-8) of
SECTION 11.
31. BRAKE DISCS, PADS, BRAKE DRUMS
AND SHOES INSPECTION
Brake Discs and Pads
I) Remove wheel and caliper but don’t discon-
nect brake hose from caliper.
2) Check front disc brake pads and discs for
excessivewear,damageand deflection.
Replace parts as necessary. For the details,
refer to p. 19-I 6 and 19-I 7 of SECT ION 19.
Be sure to torque caliper guide pins to specifi-
cation for reinstallation.
Brake Drums and Shoes
I) Remove wheel and brake drum.
2) Check rear brake drums and brake linings for
excessive wear and damage, while wheels and
drums are removed. Also check wheel cylin-
ders for leaks, at the same time. Replace
these parts as necessary.
For the details, refer to p. 19-21 and p. 19-
22 of SECTION 19.
32. BRAKE HOSES AND PIPES INSPECTION
Check brake hoses and pipes for proper hook-
up, leaks, cracks, chafing and other damage.
Replace any of these parts as necessary.
CAUTION:
After replacing any brake pipe or hose, be
sure to carry out air purge operation.
33. BRAKE FLUID INSPECTION AND
CHANGE
[INSPECTION]
1) Check around master cylinder and reservoir
for fluid leakage.
If found leaky, correct.
2) Check fluid level
If fluid level is lower than the minimum level
of reservoir, refilling is necessary. Fill reservoir
with specified brake fluids.
Brake fluid Speifi;t3ons
For the details, refer to MAINTENANCE
SERVICE (p. 19-42) of SECTION 19.
CAUTION:
Since the brake system of this car is factory-
filled with glycol-base brake fluid, do not
use or mix different type of fluid when
refilling the system; otherwise serious
damage will occur. Do not use old or used
brake fluid, or one taken from unsealed
container.
[CHANGE]
1) Change brake fluid. As fluid change procedure,
drain existing fluid from brake system com-
pletely, fill the system with above recom-
mended fluid and carry out air purge opera-
tion.
For description of air purge, refer to p. 19-46
and 19-47 of SECTION 19.
34. BRAKE PEDAL INSPECTION
Check brake pedal travel.
For -checking procedure, refer to PEDAL TRA-
VEL CHECK (p. 19-43) of SECTION 19.
35. BRAKE LEVER AND CABLE
INSPECTION
Parking Brake Lever
I) Check tooth tip of each notch for damage or
wear. If any damage or wear is found, replace
parking lever.
2) Check parking brake lever for proper opera-
tion and stroke, and adjust it if necessary.
For checking and adjusting procedures,
refer to PARKING BRAKE INSPECTION
AND ADJUSTMENT (p. 19-44) of SECTION
19.

Wheel repairs that use welding, heating, or peen-
ing are not approved. All damaged wheels should
be replaced.
[Tire demounting and mounting]
Use a ‘tire changing machine to mount or de-
mount tires. Follow the equipment manufac-
ture’s instructions. Do not use hand tools or tire
irons alone to change tires as they may damage
the tire beads or wheel rim.
Rim bead seats should be cleaned with a wire
brush or coarse steel wool to remove lubricants,
old rubber and light rust. Before mounting or
demounting a tire, the bead area should be
well lubricated with an approved tire lubricant.
After mounting, inflate to 220kPa (32 psi) so
that beads are completely seated.
WARNING:
Do not stand over tire when inflating. Bead
may break when bead snaps over rim’s
safety hump and cause serious personal
injury.
Do not exceed 240kPa (35 psi) pressure
when inflating. If 220kPa (32 psi) pressure
will not seat beads, deflate, re-lubricate and
reinflate. Over inflation may cause the bead
to break and cause serious personal injury.1
Inflate to specified pressure.
[Tire repair]
There are many different materials and techni-
ques on the market to repair tires. As not all of
these work on all types of tires, tire manufactu-
rers have published detailed instructions on how
and when to repair tires. These instructions can
be obtained from the tire manufacturer.

[Caliper OPERATION]
Single piston floating caliper type
The single piston floating caliper type brake is
employed in this model. One cylinder and one
piston are used for this type. (The cylinder is
constructed as a monoblock with the caliper.)
Fluid pressure generated in the cylinder causes
the pad (1) on the piston side to press against
the disc. At the same time, the floating type
caliper body is moved to the right by the cylin-
der pressure, as shown in below figure, which
pulls pad (2) against the disc and so brakes the
wheel.
Caliper body
\Brake disc (rotor)
Fig. 19-6 - ’
The disc brake has no servo assistance as in drum
braking, and it is necessary to increase the work-
ing pressure of the piston and pad. For this pur-
pose, the wheel cylinder has a large bore. Even
only a little change in clearance between the disc
and pad has therefore a large influence on the
brake pedal stroke. It is necessary to have the
clearance adjusted to the minimum at all times,
by means of the piston (rubber) seal.

When oil pressure is applied to the piston, the
piston moves forward. The rubber seal, which
exerts considerable pressure against the piston,
moves with the cylinder. However, as a part of
the rubber seal has been fixed into a groove in
the cylinder, the shape of the rubber seal is dis-
torted toward internal end of the cylinder, as
shown in above figure. When pressure is taken
off from the foot brake pedal and fluid pressure
is released from the piston, a restoring force is
generated at the seal and pushes the piston back.
As the pads wear away and the clearance be-
tween the disc and pads becomes larger, the
piston moves a larger distance. The seal then
could change in shape further but, since the end
of the seal is fixed into the groove in the cylin-
der, the distortion is limited to the same amount
as previously described. The piston moves
further to cover the distance of clearance. The
piston returns by the same distance and the
rubber seal recovers its shape as described
above and thus the clearance between the disc
and pads are maintained in adjustment.
