KTM 990 SUPER DUKE - Manual (Page 47)

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 away, the
steel components of the brake pad will rub against the brake disc, imparing the braking
effect and destroying the brake disc.

Checking the rear brake fluid level
The brake fluid reservoir for the rear brake is located on the rear right of the vehicle and has
a "MIN" and a "MAX" mark. The brake fluid level may not fall below the "MIN" mark when
the vehicle is parked in an upright position.
– If the brake fluid level drops below the minimum either the brake system has a leak or
the brake pads are completely worn down. In this case, consult an authorized KTM dealer
immediately.
– Have the brake fluid changed at an authorized KTM workshop every 2 years.
