Important: Perform Maintenance Operation 42–11 before lubricating the slack adjusters.

Automatic slack adjusters must be lubricated periodically to ensure proper brake operation.

Warning: Failure to lubricate slack adjusters could lead to dragging brakes or a brake failure, resulting in property damage, personal injury, or death.

Lubricate the slack adjuster at the grease fitting until grease is forced past the pressure-relief capscrew or past the gear splines around the inboard snap ring. Use high-temperature, NLGI Grade 1 waterproof grease. See Fig..
