Genuine Pontiac Firebird Starter Brush

The Pontiac Firebird Starter Brush makes sure that the starter motor receives stable electrical contact so that the engine reliably cranks up. Situated at the front of the rotating armature, the Starter Brush presses against the commutator to deliver battery power supplied by the solenoid when the driver turns the key to start. The Starter Brush maintains smooth electrical current flow to create electromagnetic forces that rotate the armature. This, in turn, rotates the drive gear that meshes with the flywheel until combustion takes control. The early Pontiac and Firebird models applied a conventional direct drive starter whose brushes transferred power directly to a large armature that generated heavy turning torque. Subsequent models would make use of smaller gear reduction units, still based on the Starter Brush array, but using a smaller high-speed armature with reduction gears for quicker spin up and less weight. The Firebird starters now spin faster while the Starter Brush has protection against overheating damage. While both styles use a copper graphite brush material and spring tension to maintain contact, the gear reduction setup subjects each Starter Brush to a higher RPM but lower torque loads, which extends wear life, and you can reliably expect Pontiac performance from the first turn of the ignition.
