BLEEDING THE HYDRAULIC CLUTCH
- Remove the cover of the clutch pump on the handlebar to bleed the
air.
- Connect the suction device to the bleeder screw (1) of the clutch cylinder
on the engine and activate it while loosening bleeder screw (1).
Continue until only fluid comes out of the bleeder screw (1).
- Tighten the bleeder screw (1).
- Disconnect the suction device.
During this operation make sure that the clutch pump reservoir level
is always sufficient to prevent the pump from drawing air. Top up with
DOT4 brake hydraulic fluid as required.
WARNING
- Use DOT4 brake hydraulic fluid for the clutch hydraulic control. Never
use DOT5 or other fluids.
- Prevent contact between brake fluid and painted parts. Brake fluid
corrodes paint.
- Only use clean brake fluid from a hermetically sealed container.
BASIC INDICATIONS FOR TM DISC BRAKES
CALIPERS
EN and MX models have floating front and rear calipers, i.e.: they are not
joined to their support. Side compensation always allows the pads to rest
on the discs in the optimum way.
In contrast, SMR/SMK models front calipers are fixed.
The brake caliper supporting screws must be secured with Loctite 243 and
tightened to 25 Nm.
PADS
The minimum thickness of the friction material must never drop below 1 mm.
In the event of replacement, we recommend that you always use the specific
TM original spare part for your motorcycle.
