Adjusting Brake - Cub Cadet Fire & Rescue 642 Operator's Manual

Adjusting Brake

The wet brake system is an internal part of the
transmission and it is adjusted externally without
opening the transmission. There are two sets of brakes
that may require adjustment. Each set consists of two
rotating friction plates placed between three fixed steel
plates operating in oil. Each set of brakes is operated
by it's respective lever arm. The brakes are properly
adjusted at the factory.
To adjust the brakes:
• Stop the vehicle on a level surface.
• Turn the ignition key to the STOP position and
remove the key.
• Block the front wheels, position the shift lever into
neutral, and make sure parking brake in not
activated.
• Use a jack to raise the rear wheels at least one inch
off the ground. Then use blocks or stands to
support the machine.
• Disconnect brake arm return spring. See Figure 20.
• Loosen the front and rear jam nuts.
