TSB 05-003-02B - FRONT BRAKE PULSATION DURING LIGHT TO MODERATE BRAKE APPLICATION
Date: 12/16/02 (supersedes 0500302A Dated June 10, 2002)
Model Year(s): 1999-2002 (WJ models built through May 10, 2002)
Description: Brake roughness or pedal pulsation when the brakes are applied. The customer may experience a vibration of the steering wheel, floor, seat, instrument panel, or a minor pedal pulsation (brake roughness) under light to moderate pedal application. The condition may be caused by excessive thickness variation of the brake rotor surface.
Details: This bulletin involves the replacement of both front brake rotors and caliper assemblies. NOTE: NEW BRAKE ROTORS MUST BE USED WITH THE NEW BRAKE CALIPERS.
Diagnosis:
1. Determine if the front brake vibration/pulsation is caused by excessive thickness variation of either front brake rotor.
2. If excessive thickness variation of the front brake rotor is at fault perform the Repair Procedure.
3. If this bulletin has already been performed, and front brake pulsation/vibration is present, do not perform the Repair Procedure. Investigate other possible cases for front brake pulsation/vibration.
Parts required:
52098672 Rotor (MSRP: $65.10 ea.)
05093174AA Caliper kit (Left & Right calipers, brake pads, attachment bolts, banjo sealing washers)
04318080AB Brake fluid (DOT3/MS-4574)
