9-5
Front brake system
A number of modifications have been made at
the front. With the new steering swivel member,
the wheel sensors are now screwed directly into
the steering swivel member.
9-5 models with the 3.0t V6 engines will be
equipped with larger front discs, previously fitted
only on 9-5 Aero models (306mm / 12.05in). In
the U.S. market, this change means that Arc
models will get the larger front disks previously
fitted only to Aero models.
A new carrier has been introduced for the front
caliper. The distance between the bolts has been
increased to reduce strain and to improve
stiffness. Torx M14 bolts have been used with a
fixed washer to protect the aluminium steering
swivel member.
ABS/ESP (Available on Arc and Aero)
A number of changes have been made in the
engine bay and, because of this, the ABS unit
has been located on a new bracket closest to the
bulkhead.
The ESP stabilizing system (Electronic Stability
Program) is available as an option. The master
cylinder and lines to the hydraulic unit have been
changed, because the ESP unit requires a
greater flow from the master cylinder to and from
the hydraulic unit. The pipe diameter in the brake
lines between the unit and the master cylinder
has been increased from 4.7mm (10.19in) to
6mm (0.24in).
All the brake systems (ABS, TC/ABS and ESP)
from model year 2002 have 6.0mm (0.24in)
brake lines between the primary cylinder and the
unit. The ABS and TC/ABS systems have 4.7mm
(10.19in) lines between the secondary and the
hydraulic unit as before.
