Checking brake disc
Measure the thickness of brake disc (A) using slide
calliper. If brake disc (A) has a wear ridge, the measurement
can be performed using two spacers (B) (e.g. 5 mm thick flat
washers). Reduce the measured dimension by the total
thickness of the two spacers (B).
Min. thickness of brake disc 37 mm.
In a ventilated disc, max. wear is 4 mm per side.
Brake disc (A) must be replaced if the wear limits have been
exceeded.
Lateral runout
Check/adjust wheel bearing play.
Measure the lateral runout of brake disc (A) by
attaching a magnetic stand complete with a dial gauge
on carrier (3). Point the tip of the dial gauge towards
the side of brake disc (A) and rotate the brake disc
more than one turn.
Max lateral runout 0.5 mm.
NB! Do not include wheel bearing play in the
measurement!
Cracks in the brake disc
Check the brake disc (A) for cracks and wear tracks.
If action is required, see the manual (Section 2-3) for
replacing the brake disc.
