Newage axles
Brake System
The service brakes consist of totally
sealed oil immersed multi-discs fitted
within the front axle. (The rear axle only
has brakes fitted as an option.)
The brake system is designed to require
the minimum of maintenance, and no
defects should normally occur.
If air is present in the system, it will be
indicated by sluggish response and by
spongy action of the brake pedal.
To bleed the system, proceed as
follows:
A Check that all connections are tight and
the bleed screws are closed.
B Check that there is sufficient oil in the
hydraulic tank.
C Attach bleeder tube (1) to the bleed
screw (2) on the front axle and immerse
the other end of the tube in a small
quantity of hydraulic oil contained in a
glass jar (3).
Slacken bleed screw and depress the
brake pedal to its full extent. Hold the
pedal down and tighten bleed screw.
Release pedal and wait 5 to 10
seconds. Slacken the bleed screw and
repeat process until the oil pumped into
the jar contains no air bubbles. Hold
down the pedal and close the bleed
screw.
Remove bleeder tube and release
pedal.
D Lock the bleed screw.
F If the dumper is fitted with four wheel
braking, repeat the above procedure on
the rear axle.
G Apply normal working load on brake
pedal for two or three minutes and
examine the entire system for leaks.
Check the oil level in the hydraulic tank.
Note: Always ensure that free play of 1
to 2 mm exists between the master
cylinder push rod and the piston when
the brake pedal is released.
