BRAKE FLUID LEVEL INSPECTION/

BRAKE PAD INSPECTION

NOTE:

For a correct reading of the brake fluid level, make
sure that the top of the handlebar brake master cyl-
inder reservoir is horizontal.

CAUTION:

Brake fluid may corrode painted surfaces or
plastic parts. Always clean up spilled fluid
immediately.

WARNING

• Use only the designated brake fluid. Other flu-

ids may deteriorate the rubber seals, causing
leakage and poor brake performance.

• Refill with the same type of fluid. Mixing fluids

may result in a harmful chemical reaction
leading to poor brake performance.

• When refilling, be careful that water does not

enter the brake master cylinder reservoir.
Water will significantly lower the boiling point
of the fluid and may cause vapor lock.

BRAKE PAD INSPECTION

1. Remove:

• Right side cover

Refer to “COWLINGS” in CHAPTER 3.

2. Apply the brake lever.
3. Inspect:

• Brake pad wear 

Wear indicator 1 nearly contacts the brake
disc 

→ Replace as a set.

Wear limit:

4.7 mm (0.19 in)
