FRIENDLY SERVICE TIPS

Braking performance will drop
down after brake chamber push
rod travel of 45 mm in brakes
applied condition. (Angle
between push rod and centre
line of slack adjuster will be less
than 90
o
.) Please do adjust
service brakes before 45 mm
travel.
2.
When drums are removed for
servicing, do not apply grease
between contact surfaces of S
cam profile and rollers. They
should be left dry for proper
rolling action. But only roller ends
which sit into shoe web are to
be greased lightly.
3.
When using repair size brake
drums and linings ensure that
drum diameters and brake lining
sizes are same on the opposite side
of the same axle.

Do not attempt to clean air dryer

old ones with new cartridge and
filter every two years.

Brake drum diameters are
recommended upto repair size II
of 329 mm. Drums should not
be used beyond 330 mm dia. as
there will be no service braking

roll over. Before that, drums
should be discarded.

Any extra air connection to
auxiliaries like air horn should be
taken from exhaust brake circuit
only and not from parking brake
circuit or service brake circuits.

be used along with exhaust
brake isolator switch for
