Brakes - Dragging Condition
NUMBER:
93-T-25
CORP.REF.NO:
235016R
DATE:
December 1992
SECTION:
5
SUBJECT:
BRAKE DRAG - INSTALL NEW SERVICE KIT
MODELS/YEARS:
1993 CUTLASS CIERA/CRUISER
CONDITION:
Some 1993 Cutlass Ciera/Cruiser models built between the start of production and Vehicle Number P6337108, may exhibit one or more of the following
brake drag symptoms:
a.
Loss of power
b.
Vehicle slowing
c.
Downshift when attempting to maintain speed
d.
Cruise control will not set
CAUSE:
This condition may be due to a stack up variation between the booster, front of dash, dash mat, and brake pedal bracket during installation. This may
cause the booster piston rod which mates with the master cylinder to extend beyond the normal setting. The master cylinder may then retain pressure
which in turn could lead to brake drag.
Note:
This condition will not affect the normal functioning of the brake lights nor the cruise control brake pedal release.
CORRECTION:
If a vehicle has one or more of the above symptoms, install GM Service Kit P/N 18021068. This kit includes the following:
a.
Two piece adjustable piston rod.
b.
Revised reaction retainer
c.
Silicone lubricant
d.
Detailed installation instructions
Parts are expected to be available on January 4, 1993. In case of limited inventory, parts will be placed on 400 control to waive VIP surcharges. Only
verifiable emergency VIP orders will be accepted. SPO will make every effort to obtain parts. However, the part will be shipped premium transportation
at dealer's expense and all other order types will be placed on backorder until the 400 control is removed.
Note:
The above condition will not be corrected by changing the booster and/or master cylinder. The only correction is the installation of the GM Service Kit
18021068.
