General information on KTM disk brakes

BRAKE CALIPERS:

The front brake calipers

[1] have 4 brake pistons each and are firmly connected to the fork

legs. The front brake disks are designed as „floating“ brake disks, i.e. they are not firmly

connected to the front wheel.

The lateral balance ensures that the brake pads always have the best possible contact to the brake

disk. Apply Loctite 243 to the screws

[2] on the brake caliper support and tighten to 45 Nm.

The rear brake caliper

[3] has 1 brake piston and is designed as a „floating brake caliper“,

i.e. it is not firmly connected to the brake caliper support. The lateral balance ensures that

the brake pads always have the best possible contact to the brake disk.

FOR SAFETY REASONS, ALWAYS HAVE MAINTENANCE WORK AND REPAIRS TO THE BRAKE SYS-

TEM PERFORMED BY AN AUTHORIZED KTM WORKSHOP.

BRAKE PADS:

Your motorcycle is equipped with sintered brake pads in the front and rear and homologated

accordingly. They guarantee maximum braking performance.

Front brake pads:

HAWK 7342-49

Rear brake pads:

TOSHIBA TTH 38 GF

BRAKE PADS AVAILABLE IN THE ACCESSORY TRADE ARE OFTEN NOT AUTHORIZED FOR OPERA-

TION OF YOUR KTM MOTORCYCLE IN ROAD TRAFFIC. THE BRAKE PADS DESIGN AND FRICTION

FACTOR AND THEREFORE THE BRAKING POWER CAN DEVIATE SIGNIFICANTLY FROM ORIGINAL

KTM BRAKE PADS. IF YOU USE DIFFERENT BRAKE PADS THAN THOSE PROVIDED WITH THE ORIG-

INAL EQUIPMENT, IT CANNOT BE WARRANTED THAT THEY ARE AUTHORIZED FOR USE IN ROAD

TRAFFIC. YOUR MOTORCYCLE WILL NOT LONGER COMPLY WITH THE REGULATIONS AUTHORIZ-

ING THE USE OF VEHICLES FOR ROAD TRAFFIC AND THE WARRANTY WILL BE VOID.

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.
