Checking the rear brake fluid level
The reservoir for the rear brake disk is located on the right side of the motor-
cycle on the rear brake cylinder.
No air bubble should be visible in inspection glass [A] when the vehicle is
parked in a vertical position.
If the brake fluid level drops below the minimum either the brake system has
a leak or the brake pads are completely worn. In this case, consult an author-
ized KTM dealer immediately.
Refilling the rear brake fluid reservoir *
Add brake fluid as soon as a bubble is visible in inspection glass [A].
To top up, remove screw [1]. Fill DOT5.1 brake fluid (e.g. Motorex Brake Fluid
DOT 5.1) up to the mark [B] on the inside of the reservoir and remount the
screw. Spilled brake fluid must be rinsed off with water.
Never use DOT5 brake fluid! It is based on silicone oil and of a purple
color. Seals and brake hoses must be especially adapted to it.
Store brake fluid out of reach of children.
Brake fluid can cause skin irritation. Avoid contact with skin and eyes. If
you get brake fluid in your eyes, rinse with plenty of water and consult a
doctor.
Don’t let brake fluid get in contact with paint, it is an effective paint remover.
Use only clean brake fluid taken from a tightly sealed container.

Checking the rear brake pads
The brake pads can be inspected from the rear. The thickness of the linings
may not be less than 1 mm (0.04 in).
At their most worn point brake pad linings should not be thinner than 1 mm,
otherwise they could lead to brake failure. For your own safety don’t put off
having your brake pads changed.
If the brake pads are replaced too late so that the lining is partly or entirely
worn, the steel components of the brake pad will rub against the brake disc,
thereby imparing the braking effect and destroying the brake disc.
