6.Clean the piston and, using the special tool, push the piston
into the cylinder.
7.With care not to allow the piston boot to be wedged, lower
the caliper assembly and fit the lock pin.
8. Using the following procedure, check the brake drag
‘d ,
torque.@ Start the engine and depress and hold the brake pedal
for five seconds.@ Stop the engine. (Approx. 200 N
[44 Ibs.])@ Rotate the brake disc ten turns in the forward direction.@ Using a spring balance, check the brake drag force.
9. If the difference between the brake drag force and hub
rotating force exceeds the standard value, disassemble the
piston and check the piston sliding surfaces for dirt and
rust, piston seal for deterioration, and lock pin and guide pin
for sliding motion.
Standard value: 70 N (15.4 Ibs.)
[4 Nm (3 ftlbs.)] or less
1. Visually check the brake pad’ thickness. Through the
opening in the caliper body.
Standard value: 10.0 mm
(-39 in.)
Limit: 2.0 mm
(.08 in.)
Caution
‘L&iReplace the pad if worn beyond the limit. At this time,
replace the pads on right and left wheels as a set.
I2. Remove the clip and, holding the cross spring with hand,
remove the pad pins.

drag torque after pad installation.
On vehicles with VCU-equipped LSD, disengage the drive
shaft and companion flange.
NOTESecure the disc to the hub with wheel nuts.
6. Securely attach the pad clip to the caliper support.
Caution
Do not deposit
&ease or other dirt on pad or brake disc
friction surfaces.
7.Clean the piston and then push the piston into the cylinder.
8.With care not to allow the piston boot to be wedged, lower
the caliper assembly and fit the lock pin.
9. Check brake drag torque as follows.
(I) Start engine and hold brake pedal down for 5 seconds.
[Approx. 200 N (44
Ibs.)](2) Stop engine.
(3) Turn brake disc forward
10 times.
(4) Check brake drag torque with spring scale.
If the difference between brake drag torque and hub torque
exceeds the standard value, disassemble piston and clean
piston. Check for corrosion or worn piston seal, andcheck
the sliding condition of the lock pin sleeve and guide
pinl/jsleeve.
Standard value: 70 N (15.4

SERVICE POINTS OF DISASSEMBLYM35LFCB
When disassembling the front disc brakes, disassemble both
sides (left and right) as a set.
7. REMOVAL OF PISTON BOOT
/ 8. PISTON
Send compressed air from the port to which brake hose is
installed and remove the pistons and piston boots.
Caution
Send the air gradually, and using the handle of a plastic
hammer etc., keep the protrusions of the two pistons
even.
If one of the two pistons is removed, the other one
cannot be removed.
9. REMOVAL OF PISTON SEAL
(1) Remove piston seal with finger tip.
Caution
Do not damage the cylinder inner surface.
(2) Clean piston surface and inher cylinder with trichloro-
ethylene, alcohol or specified brake fluid.
Specified brake fluid: Conforming to DOT3
INSPECTIONMOBLGCBl Check cylinder for wear, damage or rust.
l Check piston surface for wear, damage or rust.
l Check caliper body or sleeve for wear.
l Check pad for damage or adhesion of grease, check
backing metal for damage.
PAD WEAR CHECK
Measure thickness at the thinnest and worn area of the pad.
Replace pad assembly, when pad thickness is less than the limit
value.
Standard value: 10.0 mm (.39 in.)
Limit value: 2.0 mm
(08 in.)
Caution
1.Whenever the pad is to be replaced, replace the pads on
both right and left wheels as a set.
2. If there is a large difference in thickness between the
pads on the right and left wheels, check the sliding
portions of the caliper.
