REPLACEMENT CAUTION / NOTICE / HINT NOTICE:
HINT: There are 2 ways of brake fluid replacement: using the Techstream or not using the Techstream. PROCEDURE 1. REPLACE BRAKE FLUID (When Using the Techstream) (a) Fill the reservoir with brake fluid.
(2) Add brake fluid to the reservoir until the fluid level is between the MAX and MIN lines on the brake fluid reservoir. Brake Fluid: SAE J1703 or FMVSS No. 116 DOT3 SAE J1704 or FMVSS No. 116 DOT4 (b) Replace the brake fluid. (1) Connect the Techstream to the DLC3 and turn the power switch on (IG). (2) Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Utility / Air Bleeding/AHB-R Utility. Chassis > ABS/VSC/TRAC > Utility
(3) Select "Brake Line Air Bleeding", and replace the brake fluid following the instructions on the Techstream. (4) After replacing brake fluid, tighten each bleeder plug. Torque: 8.3 N·m {85 kgf·cm, 73 in·lbf} (c) Install the brake master cylinder reservoir filler cap assembly. (d) Clear the DTCs. Click here (e) Turn the Techstream off then turn the power switch off. (f) Inspect for brake fluid leaks. 2. REPLACE BRAKE FLUID (When Not Using the Techstream) NOTICE:
(a) Remove all 4 wheels. Click here (b) Enter ECB (Electronically Controlled Brake system) Invalid Mode. (1) Perform the procedure listed below within 1 minute.
(c) Fill the reservoir with brake fluid.
(2) Add brake fluid to the reservoir until the fluid level is between the MAX and MIN lines on the brake fluid reservoir. Brake Fluid: SAE J1703 or FMVSS No. 116 DOT3 SAE J1704 or FMVSS No. 116 DOT4 (d) Replace the brake fluid. HINT: When replacing the brake fluid using vacuum, the brake fluid bottle can be inverted and placed on the reservoir filler opening. (1) Connect a vinyl tube to the bleeder plug of the front disc brake cylinder assembly RH. (2) Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.*1 (3) When fluid stops coming out, tighten the bleeder plug, and then release the brake pedal.*2 (4) Repeat steps *1 and *2 until new brake fluid comes out. (5) Tighten the bleeder plug completely. Torque: 8.3 N·m {85 kgf·cm, 73 in·lbf} (6) Replace brake fluid from the front disc brake cylinder assembly LH using the same procedure as for the RH side. (7) Connect a vinyl tube to the bleeder plug of the rear disc brake cylinder assembly LH. (8) Depress the brake pedal several times, and then loosen the bleeder plug with the pedal depressed.*3 (9) When fluid stops coming out, tighten the bleeder plug, and then release the brake pedal.*4 (10) Repeat steps *3 and *4 until new brake fluid comes out. (11) Tighten the bleeder plug completely. Torque: 8.3 N·m {85 kgf·cm, 73 in·lbf} (12) Replace brake fluid from the rear disc brake cylinder assembly RH using the same procedure as for the LH side. (13) Turn the power switch off. (e) Inspect for brake fluid leaks. (f) Adjust the brake fluid level in the reservoir. Click here (g) Install the brake master cylinder reservoir filler cap assembly. (h) Install the 4 wheels. Click here |
