Safety and Service Precautions
^
The normal working pressure of the anti-lock brake boost system is 1,650 to 2,050 psi. System pressure must be pumped down before any
pressure lines are loosened or disconnected. Failure to do so could result in personal injury.
^
To reduce system pressure:
-
Turn igniton switch off.
-
Apply brakes 45 to 50 times (until pedal is firm).
^
The accumulator tank and small accumulator on the booster pump contain high pressure gas charges. Do not puncture or attempt to
disassemble either of these components at any tfme.
^
Wear safety goggles when disconnecting fluid lines.
^
Keep work area clean. Avoid contamination of system components with dirt or foreign material.
^
Use only new Mopar brake fluid or equivalent meeting SAE J1703 and DOT 3 standards.
^
Prevent brake fluid from contacting painted surfaces. If contact occurs, flush thoroughly with water.
