3. Place the brake assembly on a work bench.
Take particular ca
re with the copper
disk, as it bends easily and may then
cause problems after reassembly, by
brushing against the winding block.
4. Back off the screws b using a 4-
mm Allen
wrench.
5. Remove the copper disk.
To reassemble the brake, carry out the above
steps in reverse order.
Remember to fully lock down all the
screws “b” (in a cross pattern), as they
may knock against the speed sensor if
left loose. Lock down the screws using a
torque wrench set for 6 Nm
After reassembling the brake, use a
comparator to
check for any curvature
of the copper disk, with a margin of
±
0.15 mm.
