If incorrect, check the stop light switch clearance. If the clear-
ance is OK, then troubleshoot the brake system.
Stop light switch clearance: 1.9 mm (0.075 in.)
HINT:
The freeplay to the 1st point of resistance is due to the play be-
tween the clevis, pedal link and pin. It is 1.0 - 6.0 mm (0.039 -
0.236 in.) on the pedal.
4. CHECK PEDAL RESERVE DISTANCE
(a) Remove the floor carpet.
(b) Release the parking brake.
With the engine running, depress the pedal and measure
the pedal reserve distance, as shown.
Pedal reserve distance at 490 N (50 kgf, 110.1 lbf):
More than 116 mm (4.57 in.)
If the reserve distance is incorrect, troubleshoot the brake sys-
tem.

BRAKE SYSTEM
PRECAUTION

Care must be taken to replace each part properly as it could affect the performance of the brake
system and result in a driving hazard. Replace the parts with parts of the same part number or
equivalent.

It is very important to keep parts and the area clean when repairing the brake system.

If the vehicle is equipped with a mobile communication system, refer to the precautions in the
IN section.

INSPECTION
1. MEASURE PAD LINING THICKNESS
Using a ruler, measure the pad lining thickness.
Standard thickness: 11.5 mm (0.453 in.)
Minimum thickness: 1.0 mm (0.039 in.)
Replace the pad if the pad's thickness is at the minimum or if
it shows signs of uneven wear.
2. MEASURE DISC THICKNESS
Using a micrometer, measure the disc thickness.
Standard thickness: 32.0 mm (1.260 in.)
Minimum thickness: 30.0 mm (1.181 in.)
Replace the disc if the thickness of the disc is at the minimum
thickness or less. Replace the disc or grind it on a lathe if it is
scored or is worn unevenly.
3. MEASURE DISC RUNOUT
Using a dial indicator, measure the disc runout at a position 10
mm (0.39 in.) from the out side edge.
Maximum disc runout: 0.07 mm (0.0028 in.)
If the bearing play and axle hub runout are not abnormal, re-
place the disc or grind it on an ºOn-Car brake latheº.
HINT:
Before measuring the runout, confirm that the front bearing pre-
load is within the specification (See page SA-16).
4. IF NECESSARY, REPLACE DISC
(a) Remove the front axle hub (See page SA-12).
(b) Remove the disc from the axle hub (See pageSA-13).
(c) Install a new disc and torque the 5 bolts.
Torque: 74 N´m (750 kgf´cm, 54 ft´lbf)
(d) Install the axle hub and adjust the front bearing preload
(See page SA-16).
