Precaution for Brake System

INFOID:0000000000958401

WARNING:

Clean any dust from the front brake and rear brake with a vacuum dust collector. Never blow with com-
pressed air.

CAUTION:

• Only use “DOT 3” brake fluid. Refer to 

MA-10, "Fluids and Lubricants"

.

• Never reuse drained brake fluid.
• Never spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it

off immediately and wash with water if it gets on a painted surface.

• After pressing the brake pedal more deeply or harder than normal driving, such as air bleeding,

check each item of brake pedal. Adjust brake pedal if it is outside the standard value. 

• Always clean with new brake fluid when cleaning the master cylinder, brake caliper and other com-

ponents.

• Never use mineral oils such as gasoline or light oil to clean. They may damage rubber parts and

cause improper operation.

• Always loosen the brake tube flare nut with a flare nut wrench.
• Tighten the brake tube flare nut to the specified torque with a

crowfoot (A) and torque wrench (B).

• Always confirm the specified tightening torque when install-

ing the brake pipes.

• Turn the ignition switch OFF and disconnect the ABS actuator

and electric unit (control unit) connector or the battery nega-
tive terminal before performing the work.

• Check that no brake fluid leakage is present after replacing

the parts.

• Burnish the brake contact surfaces after refinishing or replac-

ing rotors, after replacing pads, or if a soft pedal occurs at
very low mileage. Refer to
