Rear Brake Calipers
Calipers should be replaced in pairs. The calipers are right- and left-handed. The difference between the two
is the arrow direction stamped on to the actuator bar, which must point toward the rear of the machine.
WARNING: Never work under a machine without safety
stands or blocking to support the machine.
− Never jack the rear of the machine without
rst stabilizing the front of the machine.
1. To reduce the weight of the machine, drain
both the recovery and solution tanks.
2. Using the lifting point (A) located on the
right anti-tip hoop, raise the front of the
machine, and place support blocks (C) under
both anti-tip hoops (B).
• Failure to stabilize the front of the
machine can result in the machine being
unstable when the rear end is lifted.
Note: The machine is shown with
the recovery tank and squeegee
removed for clarity. It is not
necessary to remove them for this
procedure.
3. Using the left side of the chassis, as close to
the center as possible (D), raise the rear of
the machine, and place blocks (F) under the
tie-down eyelets (E).
Remove Both Right and Left Wheels
4. Remove the 5 screws (I) that secure the brake
rotor to the wheel, and rest the rotor on the axle.
5. Using a sharp tool, such as a knife or chisel, pry
the dust cap (L) off the wheel hub.
6. Using a 17mm socket, remove the screw (G) and
washer (H) that secures the wheel to the axle,
and remove the wheel.
7. Repeat for the second wheel.
