    DESCRIPTION

    When applying the brakes during slow speed driving and in cold weather conditions, some vehicles may have a squeak noise coming from the front brakes. This may be caused by resonance in the pad, disc, and caliper.

    A modified mounting support for the front brake calipers and modified pads have been introduced to correct this concern.

    Customers having this concern should have their vehicle repaired using the following repair procedure.

    REPAIR PROCEDURE

    Perform the appropriate repair procedure as follows:

    ^ 2.3L vehicles with VINS lower than JM1BK****41 133301 (produced before December 17, 2003) perform REPAIR PROCEDURE "A".

    ^ 2.OL with VINS from JM1BK****41 100001 to JM1BK****61 433115 (produced before September 19, 2005) perform REPAIR PROCEDURE "B".

    ^ 2.3L with VINS from JM1BK****41 133302 to JM1BK****61 433115 (produced before September 19, 2005) perform REPAIR PROCEDURE "C".




    REPAIR PROCEDURE "A"

    1. Verify customer concern.

    NOTE :

    If service bulletin 04-001/05 was already performed on this vehicle, the updated caliper mounting supports will already be installed. Verify that the updated supports are installed through visual inspection.

    ^ If updated caliper mounting supports are not installed, continue with REPAIR PROCEDURE "A".

    2. Replace front brake caliper mounting support assemblies and front pad & shim set with the modified parts according to Workshop Manual (section 04-11 FRONT BRAKE (DISC) REMOVAL/INSTALLATION).

    NOTE :

    Use new bolts 9975-60-230, two (2) per mounting support. The thread pitch is different than original. Do not reuse original mounting support and bolts.

    3. Procede to REPAIR PROCEDURE "B".
