REPLACEMENT

CAUTION / NOTICE / HINT

NOTICE:

• Move the shift lever to P and apply the parking brake before replacing the brake fluid.
• Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while replacing the brake fluid.
• If brake fluid leaks onto any painted surface, immediately wash it off.
• Do not operate the brake pedal with 2 or more breeder plugs open.
• During fluid replacement, DTCs for pressure sensor malfunctions, etc. may be stored. After fluid replacement and if instructed in the procedures, clear the DTCs.

HINT:

• Can replace the brake fluid using vacuum.
• If any work is performed on the brake system or if air in the brake lines is suspected, bleed the air from the brake system.

PROCEDURE

1. START DIAGNOSTIC MODE

NOTICE:

• Before performing inspections or repairs which may cause warning messages to be displayed or DTCs to be stored, such as a simulation test or road test, it is necessary to enter start diagnostic mode so that unnecessary warning messages are not sent to the service center.
• Make sure to keep the ignition switch ON until the brake fluid replacement is completed as diagnostic mode is canceled when the ignition switch is turned off.

(a) Perform Start Diagnosis Mode.

2. REMOVE CENTER COWL TOP VENTILATOR LOUVER

(a) Disengage the 2 hooks and separate the hood to cowl top seal from the cowl top ventilator louver sub-assembly.

(b) Disengage the 2 claws and 5 guides to remove the center cowl top ventilator louver from the cowl top ventilator louver sub-assembly.

3. REMOVE BRAKE MASTER CYLINDER RESERVOIR FILLER CAP ASSEMBLY

(a) Remove the brake master cylinder reservoir filler cap assembly.

4. FILL RESERVOIR WITH BRAKE FLUID

(a) Fill the reservoir with brake fluid.

Brake Fluid:

SAE J1703 or FMVSS No. 116 DOT3

SAE J1704 or FMVSS No. 116 DOT4

NOTICE:

• Make sure that there is sufficient brake fluid in the reservoir.
• Do not remove the filter from the brake master cylinder reservoir and be sure to fill the brake master cylinder reservoir with new brake fluid to avoid any potential contamination of the brake system. Contamination, for example by dirt particles or mineral oil, could lead to functional brake problems.

HINT:

The brake fluid bottle can be inverted and placed on the reservoir filler opening.

5. REPLACE BRAKE FLUID

NOTICE:

Make sure to keep the ignition switch ON until the brake fluid replacement is completed as brake fluid diagnosis startup is canceled when the ignition switch is turned off.

(a) Remove the bleeder plug cap.

(b) Connect a vinyl tube to the bleeder plug.

(c) Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.*1

NOTICE:

• Add brake fluid to keep the level between the MIN and MAX lines of the reservoir while replacing the brake fluid.
• Do not operate the brake pedal with 2 or more breeder plugs open.

(d) When fluid stops coming out, tighten the bleeder plug and release the brake pedal.*2

(e) Repeat steps *1 and *2 until new brake fluid comes out.

(f) Tighten the bleeder plug completely.

Torque:

8.3 N·m {85 kgf·cm, 73 in·lbf}

(g) Install the bleeder plug cap.

(h) Repeat the above steps to replace the brake fluid of the brake lines for each wheel.
