• 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 components.
• 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 crow-

foot (A) and torque wrench (B).

• Always confirm the specified tightening torque when installing the

brake pipes.

• Brake system is an important safety part. If a brake fluid leak is

detected, always disassemble the affected part. If a malfunction is
detected, replace part with a new one.

• Turn the ignition switch OFF and disconnect the ABS actuator and

electric unit (control unit) connector or the battery negative 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 replacing rotors, after replacing pads, or if a soft pedal

occurs at very low mileage. 

- Front brake pad: Refer to 

BR-14, "BRAKE PAD : Inspection and Adjustment"

.

- Front disc rotor: Refer to 

BR-14, "DISC ROTOR : Inspection and Adjustment"

Precautions for Removing of Battery Terminal

INFOID:0000000010078174

•  When removing the 12V battery terminal, turn OFF the ignition

switch and wait at least 30 seconds.
NOTE:
ECU may be active for several tens of seconds after the ignition
switch is turned OFF. If the battery terminal is removed before ECU
stops, then a DTC detection error or ECU data corruption may
occur.

•  For vehicles with the 2-batteries, be sure to connect the main bat-

tery and the sub battery before turning ON the ignition switch.
NOTE:
If the ignition switch is turned ON with any one of the terminals of
main battery and sub battery disconnected, then DTC may be
detected.

•  After installing the 12V battery, always check "Self Diagnosis Result" of all ECUs and erase DTC.

NOTE:
The removal of 12V battery may cause a DTC detection error.
