● Place the new pads (2) in position.
● Place the new pin (1) in position, and then twist its ends.

brake uid leaks might then occur.
● Always replace the pads of the two front
calipers at the same time.
► Check the pads for wear before every start-up.
► Never drive with excessively worn pads
(minimum thickness for the D18 4-piston
calipers (front): 4mm).
► The brake is an essential safety element. If the
braking system is defective or you have the
slightest doubt, do not put the kart in service.
