2004 NISSAN TERRANO brake fluid

6. Loosen/remove mounting nuts between actuator and bracket.
Installation
CAUTION:
After installation, pay attention to the following points:
IRefill brake fluid and bleed air. Refer to ªCHECK AND
ADJUSTMENTº, BR-5 and ªBleeding Brake Systemº,
ªBRAKE HYDRAULIC LINEº, BR-8, respectively.
1. Install actuator on bracket without tightening fixings.
2. Assemble brake tubes to actuator without tightening tube nuts. Ensure that correct tubes are connected to each port.
3. Fully tighten actuator and bracket fixings to specified torque.
4. Fully tighten flare nuts to specified torque, BR-9.
5. Secure ABS control unit harness connector and battery cable.

How to Perform Trouble Diagnoses for Quick
and Accurate Repair
INTRODUCTION
The ABS system has an electronic control unit to control major
functions. The control unit accepts input signals from sensors and
uses this data to compute control characteristics to instantly drive
the actuators. It is essential that both kinds of signal are accurate
and stable. It is also important to check for conventional brake
system incidents: such as air leaks in booster lines, lack of brake
fluid, or other incidents with the brake system.
It is much more difficult to diagnose an incident that occurs inter-
mittently rather than catastrophically. Most intermittent incidents are
caused by poor electric connections or improper wiring. In this
case, careful checking of suspicious circuits may help prevent the
replacement of good parts.
A visual check may not be sufficient to determine the cause of the
incidents, so a road test should also be conducted.
Before undertaking actual checks, take a few minutes to talk with
a customer who approaches with an ABS complaint. The customer
is a very good source of information on such incidents; 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 ªconventionalº incidents first.
This is one of the best ways to troubleshoot brake incidents on an
ABS controlled vehicle.

Checking Steering Wheel Turning Force
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-ture.Temperature: 50É - 80ÉC (122 - 176ÉF)
Tires need to be inflated to normal pressure.
