TECHNICAL SUPPORT - TROUBLE TRACERS
INCORRECT ASSEMBLY 3
APPEARANCE
Blue spots, darker colour of
some disc areas. Evidence of
localised overheating
CAUSE
Excessive hub run-out.
Uneven disc-to-pad contact
generates excessive
oscillation which in turn
leads to localised heat
generation – subsequently
discolouration (blueing)
EFFECT
Progressively increasing
noise and vibration
REMEDY
Correct the wheel hub
run-out and ensure that this
falls within the correct
tolerances
