help of the transport safety wear gauge

Have damaged or very dirty brake pads
replaced. Contact specialist dealer.
2 Push brake lever and hold.
3 In doing so, check whether the transport safety
wear gauge can fit between the brake pad
supporting plates.
If the transport safety wear gauge fits between
the supporting plates, the brake pads have
not reached their wear limit. Contact your
specialist dealer if they are worn.
Checking the brake rotors
Put on gloves as the brake rotor is very sharp. 1
Take hold of brake rotor and joggle it gently to
check whether the brake rotor is positioned
against the wheel free of play.
2 Check that the brake pads move uniformly
and symmetrically back towards the brake
rotor when you pull and release the brake lever.
If the brake rotor can be moved or the brake
pads move erratically, contact your specialist
dealer.
3 Check that the brake rotor is no less than
1.8 mm thick at any point.
If the brake rotor is under the wear limit and is
less than 1.8 mm thick, the brake rotor must
be replaced. Contact specialist dealer.
