FLU I D
DIAGNOSIS AND TESTING - BRAKE FLUID
CONTAMINATION
In dications of flu id conta mina tion a re swollen or
deteriorated rubber parts.
Swollen rubber parts in dicate the pr esence of
petroleum in the brake fluid.
To t est for cont aminat ion, put a small amoun t of
dr ained brake fluid in clea r glass ja r. If flu id sepa -
rates into layers, there is miner al oil or other flu id
contamina tion of t he br ake fluid.
If brake fluid is cont aminated, drain an d thor-
oughly flush system . Replace m aster cylin der, ALB
Contr oller, ca liper seals, Antilock Brakes hydraulic
unit and all hydrau lic fluid h oses.
STANDARD PROCEDURE - BRAKE FLUID
LEVEL
Always clea n the master cylin der reservoir and
caps befor e checking flu id level. If n ot cleaned, dirt
could en ter the fluid.
The fluid fill level is indica ted on th e side of t he
master cylinder reservoir (Fig. 13).
The correct fluid level i s to the MAX indicator on
the side of the reser voir. If necessar y, add fluid to the
pr oper level. (Refer to LUBRICATION & MAINTE-
NANCE/FLUID TYPES - DESCRIPTION).
SPECI FI CAT I ON S
BRAKE FLUID
The brake fluid to be used in this v ehicle must be
approved to MB 331.0, such as MOPAR! part num -
ber 0459625AC. If the approved product is n ot avail-
able, use a DOT 4 br ake flu id: minimum dry boilin g
point (ERBP ) 500°F, m inimum wet boiling poin t
(WERBP) 356°F, maximu m viscosit y 1500 mm
2
/s,
conforming to FMVSS 116 a nd ISO 4925. No other
type of br ake flu id is r ecommen ded or approved for
usage in the vehicle brake system. Use only appr oved
brake fluid or a n equivalent from a tightly sealed
container.
Use br ake fluid
CAUTION: Never use reclaimed brake fluid or fluid
from an container which has been left open. An
open container of brake fluid will absorb moisture
from the air and contaminate the fluid.
CAUTION: Never use any type of a petroleum-based
fluid in the brake hydraulic system. Use of such
type fluids will result in seal damage of the vehicle
brake hydraulic system causing a failure of the
vehicle brake system. Petroleum based fluids would
be items such as engine oil, transmission fluid,
power steering fluid, etc.
FLU I D RESERV OI R
REMOVAL
(1) Usin g a suct ion gu n remove as much brake
fluid from the reservoir as possible (Fig. 14).
(2) Disconn ect the electr ical connect or for the
brake fluid level indicator (Fig. 14).
(3) Remove the fluid reservoir (Fig. 14). Seal off
the ends and bore holes w ith plugs.
INSTALLATION
(1) In st all the fluid reservoir and fill with fluid
(Fig. 14).
(2) Bleed t he brake system.
