Caution / Notice / Hint
WARNING:
The Techstream must be used for air bleeding. If not used, the air bleeding will be incomplete, which is hazardous and may lead to an accident.
NOTE:
- Adjust the brake fluid level so that the brake fluid level is at the MAX line with the engine switch on (IG).
- Perform air bleeding with the shift lever in P and the parking brake applied.
- As brake fluid may overflow when bleeding, do not place the brake fluid can on the brake master cylinder reservoir assembly filler opening.
- Perform air bleeding while maintaining the brake fluid level between the MAX and MIN lines on the brake master cylinder reservoir assembly.
- Air bleeding will be difficult if the following occurs:
- The brake actuator hose (the hose between the brake booster pump assembly and brake master cylinder reservoir assembly) is higher than the brake fluid level and air enters the brake actuator hose.
- During the bleeding procedure, air enters the brake booster pump assembly while it is operating.
- With the battery connected, the brake control system operates when a door courtesy switch or brake pedal is operated even with the engine switch off. Therefore, if performing any work where it is possible for air to become trapped inside the brake actuator hose, disconnect the 2 brake booster pump connectors before work.
- While performing air bleeding, the accumulator pressure drop may cause a buzzer to sound. As there is no problem, continue with air bleeding.
- During air bleeding, DTCs for pressure sensor malfunctions, etc. may be stored. After air bleeding and if instructed in the procedures, clear the DTCs.
- Do not allow brake fluid on any painted vehicle body surface. If brake fluid leaks onto any painted surface, immediately wash it off.
- When bleeding air, select the suitable procedure according to the table below.
Replaced/Installed Item Work Procedure Flexible hose (front/rear) Bleed brake line Disc brake cylinder assembly (front/rear) Brake actuator assembly Bleed brake system Brake master cylinder reservoir assembly Brake stroke simulator cylinder sub-assembly Brake master cylinder sub-assembly - When bleeding air from the brake fluid, do not use a method that applies a negative pressure.*
- Removal and installation procedures for the actuator assembly are included in the removal and installation and replacement procedures for the brake stroke simulator cylinder sub-assembly and brake master cylinder sub-assembly. As a result, make sure to perform air bleeding. Do not select "Master Cylinder or Stroke Simulator has been removed" for the air bleeding selection.
