BLEEDING
CAUTION / NOTICE / HINT
CAUTION:
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.
NOTICE:
- Perform air bleeding with park (P) selected and the parking brake applied.
- As brake fluid may overflow when bleeding, do not place the fluid can on the reservoir filler opening.
- Perform air bleeding while maintaining the brake fluid level between the MAX and MIN lines on the brake fluid reservoir.
-
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 fluid level and air enters the hose.
- During the air bleeding procedure, air enters the brake booster pump assembly while the pump motor is operating.
- 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.
- Release the parking brake while the linear valve offset calibration procedure.
- 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.
