Bleeding Brake System

WARNING: This page is about a different car, the 2013 Infiniti M56 and 2013 Infiniti M37. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

Turn the ignition switch OFF and disconnect the ABS actuator and electric unit (control unit) connector or the battery negative terminal before performing work.
Monitor the fluid level in the reservoir tank while performing the air bleeding.
If the brake fluid contacts the brake caliper assembly and disc rotor, quickly wipe it off.

Check that there is no foreign material in the reservoir tank, and refill with new brake fluid.
CAUTION:
- Never reuse drained brake fluid.
- Never allow oils other than brake fluid to enter the reservoir tank.
Connect a vinyl tube to the bleeder valve of the rear right brake.
Fully depress the brake pedal 4 to 5 times.
Loosen the bleeder valve and bleed air with the brake pedal depressed, and then quickly tighten the bleeder valve.
CAUTION: Cover crowfoot and flare nut wrench with a cloth as not to damage the brake caliper assembly.
Repeat steps 3 and 4 until all of the air is out of the brake line.
Tighten the bleeder valve to the specified torque.

Repeat steps 1 to 6. Occasionally fill with the brake fluid in order to keep the reservoir tank at least half full. Bleed air in the following order: rear right brake → front left brake → rear left brake → and front right brake.
Check that the fluid level in the reservoir tank is within the specified range after air bleeding.
Check each item of brake pedal. Adjust it if the measurement value is not the standard. Refer to "INSPECTION AND ADJUSTMENT ".
