TECHNICAL SERVICE BULLETIN
PARK BRAKE LEVER RATTLE - OR INCORRECT LEVER TRAVEL
Model(s): ALL 1991 AND 1992 SATURNS
Bulletin No.: SATURN 92-T-26
Date: 05/22/1992
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
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:
- 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.
PARK BRAKE LEVER DESIGN DETERMINATION Measure the length of the threaded rod from the center of the pivot pin attachment to the end of the rod (A).
NOTE
You must remove the center console to measure the threaded rod. Refer to "Park Brake Adjustment" in the "Brakes Service Manual" and follow the console removal and installation procedures.
- FIRST DESIGN The length of the threaded rod from center of the pivot pin attachment to the end of the rod (A) is less than, or equal to 147mm (5.78 in.). The first design equalizer is larger than the second design.
- SECOND DESIGN The length of the threaded rod from center of the pivot pin attachment to the end of the rod (A) is greater than 158mm (6.22 in.). The second design equalizer is smaller than the first design.
