INTRODUCTION
GENERAL
This section has a description and the service
procedures for the brake system. The brake system
includes the following parts: master cylinder, master
cylinder with brake booster [only available lift truck
models H2.00–3.00XL (H40–60XL)], brake shoes,
wheel cylinders, a single inching/brake pedal and
linkage, and the parking brake system.
Two sizes of service brakes are used on the H3.00XL
(H60XL) lift trucks: a 260 mm (10.25 in) or a 310 mm
(12.20 in). New drive wheels and tires are required for
the larger diameter service brake. Both sizes of service
brakes are described in this section. A troubleshooting
section is included at the end of this section.
SERVICE BRAKES AND PARKING BRAKE
DESCRIPTION AND OPERATION
Service Brakes
A service brake assembly is installed on the brackets at
each end of the drive axle. The parts of the service brake
assembly for the 260 mm (10.25 in) brake are shown in
FIGURE 2. The parts of the service brake assembly for
the 310 mm (12.20 in) brake are shown in FIGURE 13.
When the brake pedal is pushed, fluid pressure from the
master cylinder causes the pistons in the wheel cylinder
to extend. The pistons expand the brake shoes against
the drum.
The clearance between the brake shoes and the brake
drum is adjusted automatically. An adjuster linkage
turns the adjuster wheel to adjust the clearance. When
the lift truck moves in the REVERSE direction and the
brakes are applied, the rear brake shoe and the adjuster
links move with the drum. This linkage moves the ad-
juster lever to rotate the adjuster wheel. The adjuster
wheel can turn only when there is clearance between the
lining of the brake shoe and the brake drum. The ad-
juster wheel can also be turned with a tool. A hole in the
drum is used for access to the adjuster wheel in the 260
mm (10.25 in) brake. A slot in the back plate gives ac-
cess to the adjuster wheel in the 310 mm (12.20 in)
brake.

Parking Brake
The parking brake system uses the service brake shoes.
Additional linkage activates the parking brake system.
When the lever is moved to apply the parking brake, the
cables and linkage expand the brake shoes against the
drum. The design of the parking brake linkage adjusts
each cable so that the tension is the same when the lever
is moved to apply parking brake.
REMOVAL AND DISASSEMBLY OF THE
260 mm (10.25 in) SERVICE BRAKES
WARNING
Brake linings can contain dangerous fibers. Breath-
ing the dust from these brake linings is a cancer or
lung disease hazard. Do not create dust! Do not clean
brake parts with compressed air or by brushing. Use
vacuum equipment approved for asbestos dust or
follow the cleaning procedure in this section. When
the brake drums are removed, do not create dust.
Do not sand, grind, chisel, hammer or change linings
in any way that will create dust. Any changes to
brake linings must be done in a restricted area with
special ventilation. Protective clothing and a
respirator must be used.

CLEANING
WARNING
DO NOT use an oil solvent to clean the master cylin-
der, wheel cylinder, or the brake linings. Use a sol-
vent approved for cleaning of brake parts. Do not
permit oil or grease in the brake fluid or on the brake
linings. Oil and grease will cause damage and leaks
in the seals of a brake system. The brakes will not op-
erate correctly if oil, grease, or brake fluid is on the
brake linings.
WARNING
Cleaning solvents can be flammable and toxic, and
can cause skin irritation. When using cleaning sol-
vents, always follow the safety instructions of the sol-
vent manufacturer.
1.Donotreleasebrakeliningdustfromthebrakelinings
into the air when the brake drum is removed.
2. Use a solvent approved for cleaning of brake parts to
wet the brake lining dust. Follow the instructions and
cautions of the manufacturer for the use of the solvent. If
a solvent spray is used, do not create brake lining dust
with the spray.
3. When the brake lining dust is wet, clean the parts. Put
any cloth or towels in a plastic bag or an airtight con-
tainer while they are still wet. Put an “ASBESTOS”
warning label on the plastic bag or airtight container.
4. Any cleaning cloths that will be washed must be
cleaned so that fibers are not released into the air.
CAUTION
Do not permit oil or grease on the brake linings be-
cause the brakes will not operate correctly. Use a
brake cleaning fluid as necessary to clean brake lin-
ings that will be installed again.
INSPECTION
1. Inspect the bore of the wheel cylinder for holes or
scratches. Replace the wheel cylinder assembly if there
is any damage.
2. Inspect the return springs for defects. Inspect the back
plate for wear where the brake shoes touch the back
plate. remove any grooves worn into the back plate.
3. Inspect the brake shoes for cracks or damage. If the
linings or shoes are worn or damaged, replace the brake
shoes. Maximum wear is to within 1 mm (0.039 in) of
contact with the rivets, or the metal shoe on bonded lin-
ings. Brake shoes must be replaced in complete sets. In-
spect the brake drums for cracks or damage. Replace
any damaged parts.
WARNING
The brake shoes on both wheels must be replaced if
any shoe is damaged. The brake performance on
both ends of an axle must be equal or the lift truck
can be difficult to steer when the brakes are applied.
4.Inspectthebrakedrumfordeepgroovesorotherdam-
age.
NOTE: If grooves must be removed from the brake
drums, do not grind more than 1.5 mm (0.060 in) from
the internal diameter of the brake drum. The maximum
limit of the internal diameter of the brake drum is 262.7
mm (10.35 in). If the internal diameter is larger than the
limit, replace the brake drum.
5. The teeth of the adjuster wheel must not be worn. The
adjuster wheel must turn freely. Check the adjuster links
for damage.
6. Make sure the parking brake levers and crank move
freely.
7. Check the grease seals and the surfaces for the seals
for wear or damage.

WARNING
The threads of the adjuster wheel are not the same
for each brake assembly. If the adjuster wheel as-
semblies are installed on the wrong brake, the brake
shoe clearance will increase each time the brakes are
applied. The adjuster wheel for the right brake has
left–hand threads. The adjuster wheel for the left
brake has right–hand threads.
Turn the adjuster wheel into the adjuster nut so that the
adjuster assembly is in its shortest position. This action
permits the brake drum to be easily installed over the
brake shoes.

Bend the lock plate over the nut.
13. Adjust the clearance of the brake shoes. Put a brake
adjustment tool or a screwdriver through the hole in the
drum. Turn the adjuster wheel so that the teeth of the ad-
juster wheel nearest the back plate move upward. Turn
the adjuster wheel until the hub will not turn. Pull the ac-
tuator away from the adjuster wheel and turn the ad-
juster wheel approximately 15 teeth in the opposite di-
rection. The brakes will adjust to the correct clearance
when they are applied while the lift truck is traveling in
the REVERSE direction.
NOTE: If the brake shoes were not replaced, loosen the
adjuster wheel approximately 25 teeth.
CAUTION
If there is too much clearance, the automatic adjust-
ers will not operate. If the clearance is too small, the
automatic adjustercannotturntheadjusterwheelto
increase the clearance and the adjuster wheel will
not turn until the brake shoes wear. If the adjuster
wheel does not move for a long operating period, the

CLEANING
WARNING
DO NOT use an oil solvent to clean the master cylin-
der, wheel cylinder, or the brake linings. Use a sol-
vent approved for cleaning of brake parts. Do not
permit oil or grease in the brake fluid or on the brake
linings. Oil and grease will cause damage and leaks
in the seals of a brake system. The brakes will not op-
erate correctly if oil, grease, or brake fluid is on the
brake linings.
WARNING
Cleaning solvents can be flammable and toxic, and
can cause skin irritation. When using cleaning sol-
vents, always follow the safety instructions of the sol-
vent manufacturer.
1.Donotreleasebrakeliningdustfromthebrakelinings
into the air when the brake drum is removed.
2. Use a solvent approved for cleaning of brake parts to
wet the brake lining dust. Follow the instructions and
cautions of the manufacturer for the use of the solvent. If
a solvent spray is used, do not create brake lining dust
with the spray.
3. When the brake lining dust is wet, clean the parts. Put
any cloth or towels in a plastic bag or an airtight con-
tainer while they are still wet. Put an “DANGEROUS
FIBERS” warning label on the plastic bag or airtight
container.
4. Any cleaning cloths that will be washed must be
cleaned so that fibers are not released into the air.
CAUTION

will not be replaced.
INSPECTION
1. Inspect the bore of the wheel cylinder for holes or
scratches. Replace the wheel cylinder assembly if there
is any damage.
2. Inspect the return springs for defects. Inspect the back
plate for wear where the brake shoes touch the back
plate. Remove any grooves or replace a worn or dam-
aged back plate.
3. Inspect the brake shoes for cracks or damage. If the
linings or shoes are worn or damaged, replace the brake
shoes. Maximum wear is to within 1 mm (0.025 in) of
contact with the rivets, or the metal shoe on bonded lin-
ings. Brake shoes must be replaced in complete sets. In-
spect the brake drums for cracks or damage. Replace
any damaged parts.
WARNING
The brake shoes on both wheels must be replaced if
any shoe is damaged. The brake performance on
both ends of an axle must be equal or the lift truck
can be difficult to steer when the brakes are applied.
4.Inspectthebrakedrumfordeepgroovesorotherdam-
age.
NOTE: If grooves must be removed from the brake
drums, do not grind more than 1.5 mm (0.060 in) from
the internal diameter of the brake drum. The maximum
limit of the internal diameter of the brake drum is 311.7
mm (12.27 in). If the internal diameter is larger than the
limit, replace the brake drum.
5. The teeth of the adjuster wheel must not be worn. The
adjuster wheel must turn freely. Check the adjuster links
for damage.
6. Make sure the parking brake cables are in good condi-
tion.
7. Check the grease seals and the surfaces for the seals
for wear or damage.
ASSEMBLY AND INSTALLATION OF THE
310 mm (12.20 in) SERVICE BRAKES
1. If the wheel cylinder was disassembled for repair, as-
semble the wheel cylinder. See FIGURE 15. Use only
HYSTER APPROVED parts.
2. Install the wheel cylinder on the back plate and tight-
en the two capscrews. Connect the brake line to the
wheel cylinder.
3. See FIGURE 14. Install the parking brake lever (18).

5. Fasten the spring, adjuster actuator (14) to the actua-
tor, adjuster wheel (11) and the brake shoe (15).
6. Put an anti–seize compound on the threads of the ad-
juster wheel. Turn the adjuster wheel into the adjuster
nut so that the adjuster assembly is in its shortest posi-
tion. This action permits the brake drum to be easily in-
stalled over the brake shoes.
7. Install the adjuster wheel (12) between the two brake
shoes. Make sure the adjuster wheel will be toward the
rear of the lift truck. Move the brake shoes apart so that
the adjuster wheel is held in position and the spring, ad-
juster actuator is in tension.
WARNING
The threads of the adjuster wheel are not the same
for each side. If the adjuster assemblies are installed
on the wrong side, the brake shoe clearance will in-
crease each time the brakes are applied. The ad-
juster wheel for the right brake has left–hand
threads. The adjuster wheel for the left brake has
right–hand threads.
8. Lubricate the back plate with a small amount of
grease where the brake shoes touch. Install the brake
shoes on the anchor (4) and engage the push rods of the
wheel cylinder. Engage the the parking brake lever (18)
in the slot in the parking brake cable as the brake shoes
are installed on the back plate.
9. Put an anchor pin that holds the brake shoes through
the back plate. Put a spring seat, spring and retainer (8)
on the anchor pin. Push the retainer on to the anchor pin
androtatetheretainer90degrees.Makesuretheretainer
is in the correct position. Install another retainer spring
assembly.
10. Install the link, parking brake (16) and the spring
(17) between the parking brake lever (18) and the brake
shoe (7).
11. Install the other spring retainers (8) that hold the
brake shoes. Make sure the parking brake (16) and the
spring (17) are correctly engaged after the spring retain-
ers are installed.
12. Install the anchor guide (5) on the anchor (4). Install
the pivot plate (9) on its anchor (22).
13. Fasten the link (10) to the actuator, adjuster wheel
(11) and put the cable around the pivot plate (9). Raise
the actuator, adjuster wheel (11) against the spring ten-
sion and connect the link (10) to the anchor (4).
14. Use the correct tools to install the return springs. In-
stall the return spring (3). Install the washer (20) and the
return spring (2). The shape of the return springs permits
them to be installed correctly in only one position. The
arrangement of the return springs on the anchors is
shown in FIGURE 16.
15. Make sure the bottom edge of the actuator, adjuster
wheel is just above the center of the teeth of the adjuster
wheel. Check for correct installation if the alignment is
not correct.
16. Clean the hub bearings and lubricate them with
wheel bearing grease. Install the hub bearings and seals
in the hub. Install the assembly on the axle housing. See
FIGURE 17. and FIGURE 18.

NOTE: To prevent damage to the inner oil seal when in-
stalling the hub, the hub and drum assembly can be tem-
porarily fastened to the wheel. Align the height of the
axle housing with hub bearings. Put grease under the
wheel and slide the wheel toward the axle housing. In-
stall the outer bearing and nut.
17. Adjust the hub bearings by tightening the nut to 205
N.m (150 lbf ft) while rotating the hub. Loosen the nut
until the hub turns freely. The torque must be less than
27 N.m (20 lbf ft). Tighten the nut to 34 N.m (25 lbf ft) or
until the first alignment position after 34 N.m (25 lbf ft).
Bend the lock plate over the nut.
18. Adjust the clearance of the brake shoes. Put a brake
adjustment tool or a screwdriver through the slot in the
back plate. Use the tool to rotate the adjuster wheel. The
actuator for the adjuster wheel will only permit rotation
in one direction. Turn the adjuster wheel until the brake
shoeshaveexpandedagainstthebrakedrumandthehub
will not turn. Use a small screwdriver to lift the actuator
away from the adjuster wheel and turn the adjuster
wheel approximately 15 teeth in the opposite direction.
The brakes will adjust to the correct clearance when
they are applied while the lift truck is traveling in the
REVERSE direction.
NOTE: If the brake shoes were not replaced, loosen the
adjuster wheel approximately 25 teeth.
CAUTION
If there is too much clearance, the automatic adjust-
ers will not operate. If the clearance is too small, the
automatic adjustercannotturntheadjusterwheelto
increase the clearance and the adjuster wheel will
not turn until the brake shoes wear. If the adjuster
wheel does not move for a long operating period, the
adjusterlinkcanwearaspotontheadjusterwheelso
that it will not turn correctly.
19. Put liquid sealant on the flange of the axle shaft. In-
stall the axle shaft and capscrews. Tighten the
capscrews to 98 N.m (72 lbf ft).
Adjustments
1. Remove the air from the brake hydraulic system. See
the procedure “Remove The Air From The Brake Sys-
tem”, under CHECKS AND ADJUSTMENTS.
2. Install the wheel on the hub. Tighten the nuts to 610 to
650 N.m (450 to 477 lbf ft).
3. Start the engine and tilt the mast backward to remove
the blocks. Push on the brake pedal. The pedal must not
touch the floor plate. Move the lift truck in REVERSE
and push on the brake pedal to permit adjusting mecha-
nism to operate.
4. The service brakes must be adjusted before the park-
ing brake can be adjusted. See FIGURE 19. and the fol-
lowing paragraphs in this section for the correct adjust-
ment of the parking brake.
