Brakes - Park Brake Lever Rattle/Incorrect Lever Travel
NO:
92-T-26
DATE:
June, 1992
GROUP:
Chassis
CORP. NO.:
285001R
SUBJECT:
Park Brake Lever Rattle and/or Incorrect Lever Travel (New Design Lever Assembly and Revised Adjustment Procedure)
MODELS
AFFECTED:
All 1991 and 1992 Saturns
CONDITION:
Some owners may comment about a rattle noise that may be heard from the center console/park brake lever area or the amount of park brake lever travel.
CAUSE:
A rattle noise may be caused by a first design park brake lever assembly that does not have an adjuster nut spring. A rattle may also occur on the second
design park brake lever due to a weak adjuster nut spring or a field adjustment not in accordance with the correct adjustment procedure.
Comments about the park brake lever travel may also result from a field adjustment not in accordance with the correct adjustment procedure.
Corrective Action
CORRECTIVE
ACTION:
A second design park brake lever was incorporated into production during March, 1991 along with its own adjustment procedure.
First Design:
All 1991 vehicles built before, and including VIN MZ115964
Second Design:
1991 vehicles built after, and including VIN MZ115965 and all 1992 vehicles
The second design lever assembly consisted of a change in the length of the threaded rod, and the addition of a spring between the equalizer and adjuster
nut. The change in the length of the threaded rod allows for increased adjustment travel. The spring prevents a possible rattle noise when the park brake
is in the released position.
To correct vehicles that have a rattle coming from the console/park brake area or have a misadjusted park brake lever, refer to one of the following
bulleted items:
NOTE:
If you are not certain of the park brake lever design, refer to "Park Brake Lever Design Determination".
^
First design - - Install adjuster nut with spring, adjust the park brake lever according to Step 5 under "Service and Adjustment" in this bulletin.
^
Second design - - Replace adjuster nut spring if necessary and adjust the park brake lever according to Step 6 under "Service and Adjustment" in
this bulletin.
IMPORTANT:
Use the correct adjustment check and service adjustment procedures dependent on park brake lever design (i.e., first design park brake adjustment
procedures must be used in conjunction with the first design park brake lever, etc.).
