Brake Pads - Wear Check; Brake System - Check - Yamaha TDM850 User Manual

7.4c Unscrew the oil filter housing drain
plug (arrowed)...
allow the oil to flow into the drain tray (see
illustrations). Check the condition of the sealing
washers on the drain plugs and discard them if they
are in any way damaged or worn. On 1996-on TDM
and TRX models, Yamaha specify using new ones as
a matter of course.
5 When the oil has completely drained, fit the plugs
to the crankcase and oil filter housing, using new
sealing washers if required, and tighten them to the
torque settings specified at the beginning of the
Chapter. Avoid overtightening, as damage to the
crankcase will result.
6 Refill the oil tank to the proper level using the recommended type and
amount of oil (see Daily (pre-ride) checks and this chapter's specifications).
With the motorcycle vertical, the oil level should lie between the maximum
and minimum level lines on the dipstick or inspection window (according to
model) (see Daily (pre-ride) checks). Install the filler cap. Start the engine
and let it run for two or three minutes. It is advisable to perform an oil
pressure check (see Section 32). Stop the engine, wait a few minutes, then
check the oil level. If necessary, add more oil to bring the level up to the
maximum level line on the dipstick or window. Check
around the drain plugs for leaks.

Check with your local refuse disposal company,
disposal facility or environmental agency to see
whether they will accept the used oil for
recycling. Don't pour used oil into drains or onto
the ground.

then the engine is experiencing wear from
break-in (new engine) or from insufficient
lubrication. If there are flakes or chips of
metal in the oil, then something is
drastically wrong internally and the
engine will have to be disassembled for
inspection and repair. If there are pieces

8.3 Brake pad wear indicator groove (arrowed) - XTZ models
1 Each brake pad has wear indicators that can
be viewed without removing the pads from the
caliper.
2 On TDM and TRX models, the turned-in
corners of the brake pad backing material form
the wear indicators - when they are almost
contacting the disc itself the pads must be
renewed. The indicators are visible by looking at
the bottom corner of the pads (see illustration).
Caution: Do not allow the pads to wear to
the extent that the indicators contact the
disc itself as the disc will be damaged.
3 On XTZ models, the indicators are in the form
of grooves in the brake pad friction material -
when the pads are worn so that the grooves are
only just visible the pads must be renewed (see
illustration).
4 If the pads are worn to or beyond the
indicators, they must be renewed. If the pads are
dirty or if you are in doubt as to the amount of
friction material remaining, remove them and
measure the amount of friction material (see
Chapter 7). Note: Some after-market pads may
use different indicators to those on the original
equipment as shown.
5 Refer to Chapter 7 for details of pad renewal.
6 Bikes used in the UK and anywhere where salt
is used on the roads are referred to Chapter 7,

1 A routine general check of the brake system
will ensure that any problems are discovered and
remedied before the rider's safety is jeopardised.
