Adjusting the Brakes
The eTriFlex machines use a single mechanical brake assembly that can be used
as a service brake, a manual parking brake, and an automatic parking brake. The
service brake and manual parking brake are controlled by a cable connected to
pedals at the operator’s left foot, while the automatic parking brake is controlled
by an 12 VDC electric brake actuator. The brake system engages 2 brake
calipers (located between each front traction motor and front traction gear box).
Checking the Brake Adjustment
1. Park the machine on a level surface, set the key switch to the O
FF
position
and disengage the manual parking brake.
2. Check each brake rod assembly for a gap between the washer and the brake
rod. A gap indicates the electric brake actuator has fully engaged each
brake. The gap should be approximately
3.3 mm (0.13 inch)
. If no gap
exists at one or both brake rod assemblies, adjust the brake linkage; refer to
Adjusting the Brake Linkage (page 6–4)
.

3. Have an assistant sit in the operator’s seat and set the key switch to the
O
N
position.
4. Ensure the brake lever (item 3 in
) at each wheel motor can be
moved by hand. A small amount of brake lever movement indicates the
actuator has fully released each brake. If no movement exists at one or both
brake levers, adjust the brake linkage; refer to
(page 6–4)
.
5. Set the key switch to the O
FF
position.
6. Observe each brake rod assembly while engaging the manual parking brake.
The gap between the washer and the brake rod should increase when the
manual parking brake is applied. The increased gap indicates the manual
parking brake is creating slightly move brake holding force than the automatic
Greensmaster® eTriFlex 3360 and 3370
