DESCRIPTION
Some vehicles may experience a grabbing condition from the rear drum brake assemblies during the first few brake applications. The condition only
occurs after the vehicle has been parked for several hours. To reduce moisture intrusion into the rear brake drums, silicone is used to seal the brake
backing plate.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Raise and support vehicle and remove rear wheels.
3. Replace rear brake drum linings using MS3 online or Workshop Manual (section 04-11 REAR BRAKE DRUM REMOVAL / INSTALLATION).
* WARNING:
Do not breathe dust or use compressed air to blow dust from storage containers or friction components. Remove dust using government-approved
techniques. Friction component dust may be a cancer and lung disease hazard. Exposure to potentially hazardous components may occur if dusts are
created during repair of friction components, such as brake pads and clutch discs. Exposure may also cause irritation to skin, eyes and respiratory tract,
and may cause allergic reactions and/or may lead to other chronic health effects. If irritation persists, seek medical attention or advice. Failure to follow
these instructions may result in serious personal injury.*
4. Inspect the rear drum brake assemblies for damaged, missing and/or improperly seated adjuster plug (A) or parking brake cable. Replace any damaged
or missing parts.
5. Inspect and clean rear brake drum surface. Machine if necessary.
