Piston sliding surface is plated. Do not polish with emery
paper even if rust or foreign materials are stuck to sliding
surface.
Check piston for score, rust, wear, damage or presence of foreign
materials. Replace if any of the above conditions are observed.

RunoutNLBR0033S02021. Secure rotor to wheel hub with at least two nuts (M12 x 1.25).
2. Check runout using a dial indicator.
Make sure that wheel bearing axial end play is within the
specifications before measuring. Refer to AX section
(“Front Wheel Bearing”,“ON-VEHICLE SERVICE”).
Maximum runout:
0.08 mm (0.0031 in)
3. If the runout is out of specification, find minimum runout posi-
tion as follows:
a. Remove nuts and rotor from wheel hub.
b. Shift the rotor one hole and secure rotor to wheel hub with
nuts.
c. Measure runout.
d. Repeat steps a. to c. so that minimum runout position can be
found.
4. If the runout is still out of specification, turn rotor with on-car
brake lathe (“MAD, DL-8700”,“AMMCO 700 and 705”or
equivalent).
ThicknessNLBR0033S0203Thickness variation (At least 8 positions):

car brake lathe.

disassembly or replacement of caliper assembly. In this
case, suspend cylinder body with wire so as not to stretch

1. Remove master cylinder reservoir cap.
2. Remove brake cable mounting bolt and lock spring.
3. Release parking brake control lever, then disconnect cable
from the caliper.
4. Remove upper pin bolt.

outer shims.
Standard pad thickness:

6. When installing new pads, push piston into cylinder body by
gently turning piston clockwise, as shown.
Carefully monitor brake fluid level because brake fluid will
return to reservoir when pushing back piston.

How to Perform Trouble Diagnoses for Quick
and Accurate Repair
NLBR0094INTRODUCTIONNLBR0094S01The ABS system has an electronic control unit to control major
functions. The control unit accepts input signals from sensors and
instantly drives actuator. It is essential that both kinds of signals are
proper and stable. It is also important to check for conventional
problems: such as air leaks in the booster or lines, lack of brake
fluid, or other problems with the brake system.
It is much more difficult to diagnose a problem that occurs intermit-
tently rather than continuously. Most intermittent problems are
caused by poor electric connections or faulty wiring. In this case,
careful checking of suspicious circuits may help prevent the
replacement of good parts.
A visual check only may not find the cause of the problems, so a
road test should be performed.
Before undertaking actual checks, take just a few minutes to talk
with a customer who approaches with a ABS complaint. The cus-
tomer is a very good source of information on such problems;
especially intermittent ones. Through the talks with the customer,
find out what symptoms are present and under what conditions
they occur.
Start your diagnosis by looking for“conventional”problems first.
This is one of the best ways to troubleshoot brake problems on an
ABS controlled vehicle. Also check related Service Bulletins for
information.
