Checking The Front Brake Fluid Level - Yamaha TT-R125Y Owner's Manual

Rear brake shoes
1. Brake shoe wear indicator
a. Wear
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to
disassemble the brake. To check the
brake shoe wear, check the position of
the wear indicator while applying the
brake. If a brake shoe has worn to the
point that the wear indicator reaches the
wear limit line, have a Yamaha dealer
replace the brake shoes as a set.

Checking the front brake
fluid level
Insufficient brake fluid may allow air to
enter the brake system, possibly
causing it to become ineffective.
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 and/
or brake system leakage. If the brake
fluid level is low, be sure to check the
brake pads for wear and the brake
system for leakage.
Observe these precautions:
When checking the fluid level, make
sure that the top of the master
cylinder is level by turning the
handlebars.

TIP
If DOT 4 is not available, DOT 3 can be
used.
6 - 2 0
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking
performance.
Recommended brake fluid:
DOT 4
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
Be careful that water does not enter
the master cylinder when refilling.
Water will significantly lower the
boiling point of the fluid and may
result in vapor lock.
Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
As the brake pads wear, it is normal
for the brake fluid level to gradually
go down. However, if the brake fluid
level goes down suddenly, have a
Yamaha dealer check the cause.
