The drum brake assembly has a self shoe clearance adjusting system so that drum-to-shoe clearance is maintained 
appropriate at all times. Rear brake is a drum type. It uses leading trailing operation when brake pedal is depressed 
and when parking brake is applied on level road.
For components, refer to “Rear Drum Brake Assembly Components”.

NOTE
Replace all components included in repair kits to service this drum brake. Lubricate parts as specified.

 

WARNING

If any hydraulic component is removed or brake line disconnected, bleed the brake system. The torque 
values specified are for dry, unlubricated fasteners.
