NOTICE: "Remove power from the machine" means use the necessary safety procedure
for your location. In the USA, this is the OSHA lockout/tagout (LOTO) procedure. More
local requirements can also apply.
You can do these types of maintenance on the disk brake:
• do an inspection of the brake as specified in the maintenance schedule,
• replace the friction pads,
• do an overhaul on the calipers,
• replace the hydraulic fluid,
• adjust the connection between the brake cylinder and the air cylinder.
For the first four types of maintenance, you must remove air from (bleed) the hydraulic circuit.
: Operation of Brake Systems, page 38 tells how to operate the disk brakes. You can use it in
some of the types of maintenance in this procedure.
WARNING:
Risk of injury or death — A machine in operation without safety guards
is dangerous.
�
You must be an approved maintenance technician.
�
Use special caution when this instruction tells you to do work with
electrical power on. Remove power from the machine for all other mainte-
nance. Obey safety codes.
�
Replace all guards and covers.
TIP:
During parts of this procedure when you open up the calipers or hydraulic lines,
put a cloth under the calipers to catch hydraulic fluid and parts that will fall. For safety,
fully remove spilled hydraulic fluid after brake maintenance. This will help you easily
identify leaks.
