BASIC INDICATIONS FOR TM DISC BRAKES
CALLIPERS
END and MX models mount floating front and rear callipers, i.e. they are
not joined to their support. Side compensation allows there to always
be optimal support of the pads on the discs. The brake callipers sup-
port screws must be secured with Loctite 243 and tightened by 25 Nm.
SMR/SMM/SMX models mount fixed front callipers, while SMM model
mounts fixed rear callipers.
PADS
The minimum thickness of the friction material must never drop below
1 mm.
In case of replacement we recommend always using TM original spare
parts for your motorcycle.
BRAKE DISCS
Wear reduces the thickness of the brake disc on the pad contact surface
(1). In their thinnest point (A) brake discs can have a maximum wear
of 0.4 mm compared to the nominal thickness. The nominal thickness
can be measured in a point (B) outside the contact surface. Check the
presence of wear in different points.
- BRAKE DISCS WITH WEAR EXCEEDING 0.4 MM ARE A SAFETY RISK. IM-
MEDIATELY REPLACE THE BRAKE DISCS AS SOON AS WEAR LIMITS ARE
REACHED.
- IT IS MANDATORY TO HAVE THE BRAKE SYSTEM REPAIRED BY AN AUTHOR-
ISED TM WORKSHOP.
BRAKE FLUID RESERVOIRS
The brake fluid reservoirs of the front and rear brake are sized so that
topping up is not necessary even if the brake pads are worn. In fact, when
the pads are worn, the fluid in the pipes tends to occupy the space left
by the pistons which have moved to allow the pad to always rest on the
disc. If the brake fluid level drops below the minimum value it means
there is a leak in the brake system or that the brake pads are beyond
the limits allowed.
BRAKE FLUID
TM fills the brake systems with top quality DOT 4 brake fluid. We rec-
ommend topping up and replacing with the same type of fluid (DOT 4).
REPLACE THE BRAKE FLUID AT LEAST ONCE A YEAR. REPLACE IT MORE
OFTEN IF YOU WASH YOUR MOTORCYCLE FREQUENTLY. BRAKE FLUID AB-
SORBS WATER. STEAM BUBBLES CAN FORM IN “OLD” FLUID EVEN AT LOW
TEMPERATURES AND THE BRAKE SYSTEM NO LONGER WORKS PROPERLY.
