Changing The Brake Fluid - Yamaha TDM900 Owner's Manual

PERIODIC MAINTENANCE AND MINOR REPAIR
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
1
and/or brake system leakage. If the
brake fluid level is low, be sure to check
2
the brake pads for wear and the brake
system for leakage.
3 Observe these precautions:
G
When checking the fluid level,
make sure that the top of the brake
4
fluid reservoir is level.
G
Use only the recommended quality
5
brake fluid, otherwise the rubber
seals may deteriorate, causing
6
leakage and poor braking perfor-
mance.
7
Recommended brake fluid:
DOT 4
8
G
Refill with the same type of brake
9
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.
G
Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
G
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled
immediately.
G
As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
