BRAKE FLUID RESERVOIRS:
The brake fluid reservoirs on the front and rear wheel brakes have been designed in such a
way that even if the brake pads are worn it is not necessary to top up the brake fluid. There
is no reason to remove the reservoir cap under normal conditions. If the brake fluid level
drops below the minimum either the brake system has a leak or the brake pads are com-
pletely worn down. In this case, consult an authorized KTM dealer immediately.
BRAKE FLUID:
KTM fills the brake systems with Motorex Brake Fluid DOT 5.1 brake fluid, one of the best
brake fluids that is currently available. We recommend that you continue to use it. DOT 5.1
brake fluid is based on glycol ether and of an amber color. If you do not have any DOT 5.1
for refilling, you may use DOT 4 brake fluid. However, you should replace it as soon as pos-
sible by DOT 5.1.
Never use DOT 5 braking fluid.
It is based on silicone oil and has a purple color. Gaskets
and brake hoses are not compatible with it.
Brake fluid is exposed to a high thermal load and absorbs moisture from the air, which
lowers the boiling point. The brake fluid should therefore be changed at the prescribed
intervals.
Have the brake fluid for the front and rear brake changed at an authorized KTM workshop
every 2 years.
BRAKE DISCS:
Wear reduces the thickness of the brake disc in the area of contact
[4]
with the brake pads.
The brake disk should not be thinner than 4.5 mm (0.18 in) at the weakest point
[A]
. Check
the wear at several points.
Brake disks that are less than 4.5 mm (0.18 in) thick are a safety hazard. Have worn brake
disks replaced immediately.
