2002-2008 B-SERIES TRUCKS – GRABBING CONDITION FROM REAR DRUM BRAKES
APPLICABLE MODEL(S)/VINS
2002-2009 B-Series Trucks
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.
