AHB Brake System Bleeding Procedure: Notes
WARNING: This page is about a different car, the 2019 Kia Soul EV. However, it is still accessible from the selected car via links, so may be relevant.
The iBAU consists of 3 brake fluid lines in total (Low/high pressure and pedal simulator lines), therefore, air bleeding should be made sequentially following the procedure below.
- Bleeding sequence: Low pressure/Pedal simulator section (iBAU 2P & Caliper 4P) → High pressure (Caliper 4P) → Fluid circulation mode (KDS)
(If skip or incomplete of about procedure, noise (Honking/Hissing) may occur.)
CAUTION:
- Do not reuse the drained fluid.
- Always use genuine DOT3/DOT4 brake Fluid. Using a non-genuine DOT3/DOT4 brake fluid can cause corrosion and decrease the life of the system.
- Make sure no dirt or other foreign matter is allowed to contaminate the brake fluid.
- Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it off immediately with water.
- When bleeding air, make sure the brake fluid is above 10 mm starting from the "MIN" line.
- To remove the reservoir tank cap to refill the brake fluid, always close the air shut-off valve of the SST.
- Improper SST tank cap installation, can damage reservoir threads and allow fluids to leak when performing fluid circulation mode.
- Do not remove the reservoir filter (To prevent foreign substances from entering)
