LUBRICATION AND MAINTENANCE CONTINUED
TRAILER - TR3000
BRAKES
WARNING!
Perform maintenance on level surface with wheels blocked. There is no parking brake
on the TR3000. Block the wheels prior to unhitching or any maintenance of the TR3000.
Uncontrolled movement of the trailer could cause death or serious injury.
Using sight window on drums’ dust shields, adjust brakes, tighten slack adjuster until brake pads touch brake drums,
then back off 1/4 turn.
Brake noise and/or sluggish brake response may indicate air in the brake line. To correct this problem perform the
bleeding procedure listed below.
Bleeding Procedure:
1.
Attach brake supply line to tractor.
2.
Actuate brake pedal to apply pressure to brake circuit.
WARNING
Wear proper hand and eye protection when searching for leaks. Use wood or
cardboard instead of hands. Hydraulic fluid under high pressure leaking from a pin
hole is dangerous as it can penetrate the skin as through injected. Death or serious
injury could occur.
CAUTION
Hydraulic fluid will squirt around hose fittings. High pressure leaks are very
dangerous.
3.
Loosen bleeder screw on top of ram. Bleed air
from ram.
4.
Tighten bleeder screw.
5.
Repeat steps 2-4 until no air is expelled.
6.
Complete steps 2-5 for all four rams.
7.
Apply brakes and check for leaks. Make sure all rams
are fully extended while applying braking force to
brake drums. If done correctly, the ram and slack
adjuster will be at 90° to each other (Figure 20).
The ram should extend approximately 1 1/2 inch
(38 mm) to 1 3/4 inch (44 mm).
8.
If brakes chatter or rams do not fully extend
repeat steps 2-7.
9.
When complete, rams must be fully retracted.
