Brake Bleeding: Service and Repair
BLEEDING
HINT:
^
If any work is done on the brake system or if air in the brake lines is suspected, bleed the air from the system.
^
When bleeding, keep the amount of the fluid within the line of reservoir between Minimum and Maximum
NOTICE:
^
Wash off the brake fluid immediately if it comes into contact with a painted surface.
^
With the reservoir cap removed, when depressing the brake pedal, the fluid will spray.
1. FILL RESERVOIR WITH BRAKE FLUID
Fluid: SAE J1703 or FMVSS NO. 116 DOT3

empty, bleed the brake master cylinder.
a) Turn the ignition switch to OFF, depress the brake pedal more than 40 times.
HINT: When a pressure in power supply system is released, reaction force becomes light and the stroke becomes longer.
b) Turn the ignition switch to ON, check that the pump stops after approximately 30 to 40 seconds
NOTICE: When the pump does not stop, repeat steps (a) and (b) again.
c) With the ignition switch remained ON, depress the brake pedal more than 20 times.
d) Follow the procedure in step 4 and bleed the right and left front brake caliper.
e) Keep depressing the brake pedal, bleed the right and left rear brake caliper.
HINT: It is not necessary to depress the pedal continuously, because brake fluid flows out by First depressing.
