General information about KTM disc brakes
BRAKE FLUID RESERVOIRS:
The brake fluid reservoirs for the front brake is designed such that it does
not need to be refilled, even if the brake shoes are worn. If the brake fluid
level drops below the minimum level either the brake system has a leak or
the brake pads are completely worn.
In this case, consult an authorized KTM dealer immediately.
BRAKE FLUID:
KTM fills the brake system with ”Shell Advance Brake DOT 5.1”, one of the
best brake fluids 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. DOT 4 shown on the lid means minimum standard. However, you
should replace it as soon as possible by DOT 5.1.
ƽ WARNING ƽ
H AVE THE BRAKE FLUID CHANGED AT LEAST ONCE ANNUALLY . I F YOU WASH YOUR
MOTORCYCLE OFTEN , THE BRAKE FLUID SHOULD BE CHANGED EVEN MORE FREQUENTLY .
B RAKE FLUID TENDS TO ABSORB WATER . T HEREFORE , VAPOR POCKETS MAY FORM IN
" OLD " BRAKE FLUIDS EVEN AT LOW TEMPERATURES , CAUSING THE BRAKE SYSTEM TO FAIL .
BRAKE DISC:
Due to wear, the thickness of the brake disc in the area of the contact
face
1 of the brake pads decreases. At their thinnest point A , the brake
discs must not be more than 0.40 mm (0.016 in) thinner than the pad's
nominal thickness. Measure the nominal thickness in a location
B outside
the contact face. Check wear in several locations.
ƽ WARNING ƽ
– A BRAKE DISK WORN DOWN 0.40 MM (0.016 IN ) OR MORE IS A SAFETY RISK . H AVE
THE BRAKE DISK REPLACED AS SOON AS IT REACHES THE SERVICE LIMIT .
– H AVE ANY REPAIRS ON THE BRAKE SYSTEM BE PERFORMED BA A KTM DEALER .
BRAKE CALIPERS:

torque of 20 Nm.
