FRONT DISC BRAKE ROTOR CHECK
35100270047
Caution
To maintain safe braking performance, the disc brak e rotors must be kept within allowable service
specifications.
Before re-finishing or re-processing the brake disc surface, the following conditions should be checke d.
Inspection itemsRemarks
Scratches, rust, saturated lining lIf the vehicle is not driven for a the of the
and weardiscs that are not in contact with lining will beco me rusty, causing
noise and shudderin.lIf grooves resultingrom excessive disc wear and scratches arenot removed prior to installing a new pad assembly, there will tarily be inappropriate contact between the disc and the lining (pad).
Run-out or drift
Excessive run-out or drift of the discs will increa se the pedal depression
resistance due to piston knock-back.
Change in thickness (parallelism)
If the thickness of the disc changes, this will cau se pedal pulsation,
shuddering and surging.
Inset or warping (flatness)
Overheating and improper handling while servicing w ill cause inset or
warping.

FRONT BRAKE DISC RUN-OUT CORRECTION
1.If the run-out of the brake disc is equivalent to o r exceeds
the limit specification, change the phase of the di sc and
hub, and then measure the run-out again.
(1) Before removing the brake disc, chalk both side s
of the wheel stud on the side at which run-out is
greatest.
(2) Remove the brake disc, and then place a dial ga uge
as shown in the illustration; then move the hub in
the axial direction and measure the play.
Limit: 0.05 mm
in.)
If the play is equivalent to or exceeds the limit,
disassemble the hub knuckle and check each part.
2.
(3) If the play does not exceed the limit specifica tion,
install the brake disc at a position
away from
the chalk mark, and then check the run-out of the
brake disc once again.
If the run-out cannot be corrected by changing the phase
of the brake disc, replace the brake disc or turn rotor
with an on the car type brake lathe
or
equivalent). Be sure to follow the exact brake lath e
manufacturer instructions. Rotors turned on the veh icle
will often have a lower run-out than a new brake di sc.

Brake disc thickness Standard
24 mm in.)
Limit: 22.4 mm

Thickness variation (at least 8 positions) The difference between any thickness measure-
ments
not be more than
i n . ) .
2. If the disc is beyond the limits for thickness, remove
and install a new one. If thickness variation excee ds
specification, replace the brake disc or rotor with
an on the car type brake, lathe
or,
equivalent). Be sure to follow the exact
lathe
manufacturer instructions.
BRAKE LINING THICKNESS CHECK
1. Remove the brake drum.
2.Measure the wear of the brake lining at the place w orn
the most.
Limit: 1.0 mm in.)
Replace the shoe and lining assembly if any locatio n
of the brake lining thickness is less than the limi t. For
information concerning the procedures for installat ion of
the shoe and lining assembly, refer to P.
Caution
1. Whenever the shoe and lining assembly is re-
placed, replace both
and LH assemblies as
a set to prevent car from to one when
braking.
2. if there is a significant difference in the
nesses of the shoe and lining assemblies on the
left and right sides, check the
condition
of the
piston.

REAR BRAKE DISC THICKNESS CHECK
1. Remove dirt and rust from brake disc surface.
2. Measure disc thickness at 4 locations or more.
Standard value: 10 mm
Limit: 8.4 mm in.)
Replace the discs and pad assembly for both sides
and right of the vehicle if they are worn beyond th e
specified limit.
REAR BRAKE DISC CHECK
Remove the caliper support, raise the caliper assem bly,
and secure it by using a wire, etc.
2.Place a dial gauge, approximately 5 mm in.) from the
outer circumference of the brake disc, and measure the
run-out of the disc.”
Limit: 0.08 mm
in.)
NOTE
To secure the disc to the hub, tighten the nuts.
REAR BRAKE DISC RUN-OUT CORRECTION
1.If the run-out of the brake disc is equivalent to o r exceeds
the limit specification, change the phase of the di sc and
hub, and then measure the again.
NOTE
The procedures for checking and changing the rear d isc
phase are the same as those for the front brake discs.
However, the play (limit value) in the hub axial di rection
is different. (Refer to
Limit: 0.05 mm in.)
2.If the problem cannot be corrected by changing the phase
of the brake disc, replace the disc or turn rotor using
an on the car type brake lathe. Be sure to follow t he
exact brake lathe manufacturer instructions. Rotors turned
on the vehicle will often have a lower’ run-out tha n a
new brake disc.
